650B Gravel Bikes: The Monster(cross) List

181 Discussion  /   shares

Looking back, 2018 was the year of 650B gravel bikes, aka 27.5" monstercross bikes. To kick off 2019, we thought it'd be fitting to debut our new Gear Index with a complete list of monstercross-style 650B gravel bikes that fit 2.1" tires and wider ("gravel plus"). Find nearly 60 bikes that suit this category, and learn about the criteria we used to select them...

Bikepacking bikes come in all shapes and sizes—everything from plus-tire hardtails to svelte gravel race rigs, and from full-squish to fully rigid steeds. One of the most prevalent configurations combines drop-bars with big tires. The term monstercross came about to define such bikes that filled the gap between cyclocross bikes and a mountain bikes. At their best, they’re do-it-all, quiver-killing rigs capable of handling singletrack and big gravel rides, yet efficient on pavement as well. The main criteria are big tires for capability on mixed-terrain and drop handlebars for the added comfort offered through multiple hand positions. To lay out the options, here’s our comprehensive list of bikes that fall into this category—650B gravel bikes, specifically. If you are interested in dirt-drop 29ers, check out our 29″ Drop-bar Mountain Bikes Gear Index.

Benchmarks for 650B Gravel Bikes

The standard benchmarks we used to select the 650B gravel bikes listed here are that each bike must fit 27.5″ (650B) tires that are 2.1″ (54mm) or wider, and was designed for use with drop bars. There are also a few in the mix that were created to run either 700C or 650B tires. Additionally, we tried to select bikes with the appropriate bottom bracket drop for 650B (close to or less than 70mm), as well as extra bottle mounts and/or rack bosses. Here’s more about the criteria we used to select them:

Why 2.1″ Tires?

All kinds of bike manufacturers are pumping out drop-bar gravel and “adventure” bikes these days, but most fall short in one standard; they don’t have the tire clearance many riders seek—mainly mountain bike converts and bikepackers. Most of these bikes are restricted to 42-45mm tires, which is fine for some people, and most gravel roads. However, for longer rides, chunkier gravel, and more rugged terrain, 27.5 x 2.1″ tires (and wider) are the sweet spot, at least in our opinion.

650B vs 27.5″

As most readers will know, 27.5″ and 650B are the same thing—both rims have exactly the same diameter of 584mm. Albeit silly, tires are still described using both imperial and metric measuring systems—inches when describing mountain components and millimeters for road. Gravel is caught in the middle. The general consensus is that tires under 50mm wide (just shy of 2″) are marketed as 650B and described in millimeters, whereas anything over 2″ is usually deemed 27.5″ and referenced in inches.

Road Plus or Gravel Plus

One of the enticing qualities that this breed of 650B gravel bikes offers is the ability to interchange two interesting types of tires while maintaining the same geometry and feel. Road Plus tires, generally defined as voluminous road-oriented tires that are 650B x 47-50mm wide, offer a plush platform that’s still fast and efficient on pavement. And, “gravel plus” tires (aka 27.5″ monstercross)—which we define as semi-slick MTB tires (2.0-2.4″)—are a good choice for dirt-touring and bikepacking.

There are a few things to note about our Gear Index list of large tire capable 650B gravel bikes (“gravel plus” or 27.5″ monstercross bikes). The factors that we found particularly important to consider are listed in the highlights (in red). These include the frame and fork material, maximum tire size (to the best of our knowledge), and the hub/dropout width specs. In addition, note the bottom bracket spec. Bottom bracket width is relevant to tire and heel clearance, usually either a 73mm mountain bike standard or 68mm road standard. Plus, we reference whether it’s threaded or PressFit (PF)—an important factor for many. Click each list item to expand the details and see a larger photo. Lists are displayed in alphabetical order, with bikes we’ve tested grouped at top (and represented with a hexagonal “T” icon):

  • 3T Exploro

    3T Exploro

    • Frame/Fork: Carbon/Carbon
    • Max Tire Size: 27.5 x 2.1"
    • Bottom Bracket: PF86
    • Dropouts (F/R): 12 x 100mm / 12 x 142mm

    The 3T Exploro is an extremely lightweight carbon frame that’s designed for speed… and off-tarmac exploration. But make no mistake, it’s more of a road bike approach to a gravel bike. With built in proprietary technologies like ‘GravelPlus’, ‘Sqaero’, and ‘RealFast’ permeating its marketing, it’s pretty clear who the target audience is. If you’re interested in rides where you leave your driveway like a bat out of hell in search of gravel, then do twice the miles you’d planned, this might be your bike. Or, if you’re a gravel racer in the market for a fast bike for this type of riding — and the occasional overnight or weekend bikepack — the 3T Exploro could be worth considering.

  • All-City Gorilla Monsoon

    All-City Gorilla Monsoon

    • Frame/Fork: Steel/steel
    • Max Tire Clearance: 27.5 x 2.4"
    • Bottom Bracket: 73mm threaded
    • Dropouts (F/R): 15 x 100mm / 12 x 142mm

    With 2.4” tires, a 73mm bottom bracket, a bi-plane fork, and a snazzy paint job, the Gorilla Monsoon is a mix of old and new, and much more dirt-friendly than you might expect. Although the geometry is fairly neutral, and not too out of the ordinary, it’s well-conceived and generally suited for riding a variety of terrain. All the while, this bike is a lot of fun. And with a nice blend of classic styling and a modern build features, such as thru-axles, short-ish chainstays, and beefy tires, the Gorilla Monsoon is certainly unique.

  • Bearclaw Thunderhawk

    Bearclaw Thunderhawk

    • Frame/Fork: Titanium/Carbon
    • Max Tire Size: 27.5 x 2.4"
    • Bottom Bracket: PF30
    • Dropouts (F/R): 12 x 100mm / 12 x 142mm

    The Bearclaw Thunderhawk, a relatively new offering in the bike world, caught our attention immediately. It’s a performance-minded 650B road plus bike that is well equipped to handle road, gravel, endurance events, and, of course, bikepacking. The double-butted titanium frame has clearance for up to 700 x 46mm (29 x 1.8″) or 650B x 60mm (27.5 x 2.4″) tires, is decked out with three bottle mounts, fender and rack mounts, plus Bearclaw’s own carbon Ramhorn fork that offers massive clearance for large tires and anything cage mounts. Stay tuned for a full review.

    • Max Tire Size: 27.5 x 2.1"
    • Bottom Bracket: T47 Threaded
    • Dropouts (F/R): 12 x 100mm / 12 x 142mm

    Ibis calls the reengineered Hakka MX their Swiss Army knife, and we think that’s a fitting description of how it fits into not only their lineup, but into any stable of bikes. According to Lucas’ review, it’s equally at home on relaxed road rides, gravel jaunts, and fast singletrack.

  • Kona Libre

    Kona Libre

    • Frame/Fork: Carbon/Carbon
    • Max Tire Size: 29 x 2.0" / 27.5 x 2.1"
    • Bottom Bracket: PF
    • Dropouts (F/R): 12 x 100mm / 12 x 142mm

    The Kona Libre is Kona’s latest off-road drop-bar platform. We positioned it as part road bike, part mountain bike, and part gravel grinder. We tested the DL, which is the 700C version, however, we wished for bigger tires. The Libre model is specced with 650B x 47mm Byways, although Kona claims it can fit 2.1″ rubber. With a high stack hight and long reach, the Libre has a rather comfortable stature, yet it excels at many things—climbing, quickness, and a really solid geometry. Consequently, it would make a great commuter that doubles as a gravel bike and weekend bikepacker, or a randonneur that occasionally comes along for gavel group rides/races.

    • Max Tire Size: 27.5 x 2.1"
    • Bottom Bracket: PF86
    • Dropouts (F/R): 12 x 100mm / 12 x 142mm

    Norco’s revamped Search XR Carbon gets the latest ‘all-road’ standards, meaty 27.5 x 2.1” tires, and mounts to carry up to five water bottles. The Norco Search XR Carbon is an expensive bike. However, it’s also a very capable bikepacking rig that might be a good fit for those who can’t avoid some paved riding to escape urban areas on the way to rougher and more remote trails. With multiple wheel size options, various rack and bottle mounts, and clearance for decent sized 650B tires, it’s also a solid option for endurance bikepacking races that would benefit from a lighter overall package.

    • Max Tire Size: 27.5 x 2.2"
    • Bottom Bracket: BB386 PressFit
    • Dropouts (F/R): 15 x 100mm / 12 x 142mm

    Last seen in Rocky’s 2016 catalog, the Rocky Mountain Solo is a bike that’s been in and out of Rocky’s lineup for years. At one point in time it was a traditional road bike, then a CX bike, and now it’s been fully revamped from the ground up as a gravel and adventure rig. The new Solo is 1x-specific and comes in three models, all featuring a 6061 SL alloy frame with a “Zero Stack” tapered headtube and a 142 x 12mm rear thru-axle. The Solo frame also features flat mount disc brakes, three bottle mounts (two in the triangle and one under the downtube), internal cable routing, and rack and fender mounts. According to Rocky, the Solo has a unique yoke design to accommodate large 700x45c or 650B x 2.2 tires, as well as a large chainring (each model is specced with a 40t ring).

    • Bottom Bracket: 73mm Threaded
    • Dropouts (F/R): 110 x 15mm / 12 x 148mm

    The Fargo is the bike that started it all. Built for long rides like the Tour divide, it’s a dirt-drop 29er at heart. Since then, Salsa has refined it to be a versatile machine. 29 x 2.6″ (or 27.5+ tires) are its sweet spot, although with a 70mm BB-drop, it can run just about anything, including 27.5 x 2.1″. While we haven’t reviewed the Fargo directly, we’ve spent plenty of time on the 29+ Deadwood, which is essentially the same bike with a color and graphics change. Here’s details about Gin’s 29 x 2.6″ Deadwood set up.

    • Bottom Bracket: BB86 PressFit
    • Dropouts (F/R): 12 x 100mm / 12 x 142mm

    The new Warbird v4 frame has a ton of updated tweaks and changes, including more mounts, tire clearance, and other bikepacking friendly features. As far as the 650B version, Warbird Force 1 650 gets a SRAM Force 1×11 drivetrain, 650B x 47mm WTB ByWay tires, Salsa Cowbell Deluxe handlebars, and KOM Light rims with 23mm internal width. Learn more over on the press release and stay tuned for a full review.

    *Note that Salsa claims the Warbird fits up to 2.0″; however, they initially specced it with 2.1″ tires, so they will fit (depending on brand, etc).

    • Bottom Bracket: 68mm Threaded
    • Dropouts (F/R): 12 x 100mm / 12 x 142mm

    In 2016, Colorado-based Why Cycles released the R+ as titanium drop-bar adventure bike that aimed to extend the limits of what a drop bar bike can do. Now in its third iteration, the R+ claims to be “everything you could ever want for a long ride.” The R+ features a beautiful titanium frame with a 31.6mm seatpost, lots of internal cable routing, and tons of mounts (more added in 2018). If you haven’t seen it already, Anthony Pease reviewed the original R+ back in 2017.

  • 333fab AirLandSea

    333fab AirLandSea

    • Frame/Fork: Steel/steel
    • Max Tire Size: 27.5 x 2.35"*
    • Bottom Bracket: 73mm Threaded
    • Dropouts (F/R): 15 x 100 / 12 x 142mm

    The AirLandSea Cascadian Rambler is the brainchild of Maxwell Kullaway, the frame builder behind Seattle-based 333Fab. This limited edition bike is described as an “all-road/off-road bicycle made to carry you and your stuff over rough tarmac, gravel, dirt roads, and muddy single-track trails typical to the PNW.” With custom graphics by Kyler Martz and a PNW inspired fade paint scheme, the AirLandSea is the only model made by 333fab in stock sizes. There are seven sizes available with progressive geometry to suit riders ranging from 5′-6’5″. Each individual size has its own size-specific tubeset with varying tube diameters.

    The AirLandSea is built around a 73mm English threaded bottom bracket with the option for a T47 BB. The T47 is recommended for those interested in rear dynamo lighting or Di2. The T47 BB works a little better for internal wiring as it allows more clearance. For the 73mm BB, 333fab worked with White Industries to use their M30 spindle in conjuction with R30 crank arms to optimize chainline.

    There are fork options as well. The tapered head tube will accommodate a 1.125″ steerer for the 65mm rake, low-trail, steel touring fork (as shown) or a tapered steerer for a carbon fork. Other options include internal routing for front and rear dynamo lighting, rear rack mounts, and choice of axle size (QR, 12mm, or 15mm axle). Every AirLandSea comes equipped with fender mounts, stainless steel PMW ‘rocker’ dropouts, and room for 27.5″ x 2.25″ tires (with 65mm fenders). *It’s likely that AirLandSea will fit tires up to 2.35″ without fenders.

    44 Bikes is a small, New Hampshire-based, custom shop run by framebuilder Kristofer Henry. One of the company’s ready-platforms is tha Huntsman, a drop-bar gravel frame suited to all types of terrain. Kris developed the Huntsman “Super Trail” when a client requested a Huntsman with room for 29 x 2.3″ tires. Now he builds them around both 650B (shown here) or 29″, depending on your wishes. All frames start at $1,850 and there are a wealth of options. The most standard set of options are a 44mm head tube, PMW’s Wright dropouts (QR or 12mm TA), two pairs of bottle mounts, internal rear brake routing along the top tube and traditional down tube routing for front and rear derailleurs. Based on tire clearance, utility, and looks, this one’s on our wish list, for sure.

    • Bottom Bracket: PF30
    • Dropouts (F/R): 12 x 100mm / 12 x 142mm

    The Hook series originated as a CX line. In 2017, Bombtrack took the Hook EXT a step further and it proved successful with riders looking for bigger tires in a gravel bike package. As a brand-new model for 2018, the Hook EXT-C builds on the success of the original but in a full carbon fiber format. The bike was designed around a sophisticated chainstay to allow for larger tires and a shorter rear end for more agile handling. For carrying duties, the EXT-C includes bottle mounts under the downtube as well as a set of triple-mounts on each fork blade. Build highlights include a SRAM Rival 1 drivetrain, flat-mount Rival hydro brakes, and a slick set of Hunt Adventure Sport offset 27.5″ wheels.

We tip our hats to those who can do it well on 25c tires too. Would said terrain be more fun, could you ride longer, could you go faster etc, if you had the right tool for the job. Also a resounding yes!” We agree. And with triple fork mounts, three pairs of frame bosses, and plenty of rack and fender mounts, it looks like a great bike for bikepacking and touring, too.

    The Crust Bombara is designed around 27.5 x 2.4″ tires and spaced for a road crankset. While Crust doesn’t put much out there about who this bike is made for, it looks to us like an Evasion light, a light touring, gravel bikepacking bike that can handle about anything.

    • Bottom Bracket: 68mm Threaded
    • Dropouts (F/R): 12 x 100 / 12 x 142mm

    The Dreamer is the slimmed down USA-made version of the Evasion. According to Crust, “Both are designed for cruising on any road you might want to follow, but the Dreamer is a little more suited for day rides and fair weather touring. The tire clearances are a little tighter, the tubes are a little lighter, and there are one or two fewer braze-ons. The geometry has been tuned a little (just a tiny bit), with a hair longer top tubes, a shade steeper head tubes, and a scant bit more rake. And we used the most modern of axles, 12mm thru-axle on the rear.”

    The Dreamer is frame is designed around 650b x 2.0” or 700 x 48mm tires and a standard 400mm carbon gravel fork (frameset comes with your choice of a Enve or Lithic carbon fork). It’s made out of .8/.5/.8 VariWall Thermlx air-hardened main tubes with 4130 CrMo elsewhere. Frame features include a tapered headtube for 1-1/8″ to 1-1/2″ external headset cups (EC34 and EC44), a 12 × 142mm Syntace style thru-axle, routing for full cable housing, and plenty of mounts (two sets of triple bosses on the downtube and a pair of bottle bosses on the seat tube).

This bike is designed for dirt touring and bikepacking, and touted as “comfortable for the long haul, but fast and nimble, while still being ready for some pretty technical/rough riding…” It’s got plenty of rack mounts and bottle bosses, and Paragon-style dropouts to either run a 148mm thru-axle rear or 135mm QR, single speed or Rolloff. The bi-plane front fork features a 100mm x 15mm thru axle.

And with multiple options for tire size and plenty of bikepacking-friendly features, that’s exactly how the GXR was conceived. The GXR features rack and fender eyelets, a full-carbon fork with two sets of Anything Cage mounts, fully external cable housing, and a custom made chainstay yoke to increase tire clearance and stiffness under load.

    As Elephant describes it:

    “The National Forest Explorer (NFE) is the ideal bike for long days of spirited riding on dirt roads. While designed to carry a small load over the wheel for day supplies, the NFE also handles well with low-riders and a rear saddle bag for overnighting. Unlike many heavy “adventure bikes” or “gravel grinders” sold by larger manufacturers, the NFE is light and responsive, built with a double-butted front triangle and 4130 rear triangle.

    The geometry is optimized for experienced riders who prefer nimble handling and a light steering input. The fork is unicrown construction with a handmade direct-mount disc tab and a beautiful bend.”

    Designed by Ride Endpoint and hand-built in Ithaca, NY, at FBM Machine Shop, the Hunter Gatherer features a steel tubeset made of 28.6 Columbus Zona and 4130 Chromoly. The Hunter Gatherer is designed for efficiency and comfort over the long haul with “a geometry that puts the rider in a more relaxed position that translates to comfort and control while cruising through multi-day adventures.” Keeping in the spirit of the category, it has relatively short 435mm chainstays to maintain responsiveness while still providing clearance for 27.5 x 2.25″ tires. The frame utilizes 12 x 142mm thru-axle standard for the rear wheel and the option of 15 x 100mm thru-axle or quick release low-trail fork with bottle bosses. It also has rear triangle and fork mounts for fenders and racks, and is equipped with three bottle cages mounted low to free up enough space for a frame bag.

    The Fairlight Secan is a unique steel frame with a custom butted and formed Reynolds 853/853-DZB front triangle, a custom 0.8/0.5./0.8 Reynolds 853 top tube (20 x 30mm oval), and a custom 1.0/0.8/0.5/0.8 Reynolds 853 Gravel DZB (double zonal butted) down tube (30 x 40mm bi-oval). It also has a custom formed 4130 rear end with 19mm round chainstays and 14mm non-taper seat stays. other frame features include Bentley x Fairlight 142 x 12mm flat-mount dropouts, front and rear Fairlight axles, Fairlight 3d printed cable guide, Di2 compatibility, front and rear mudguard mounts, rear rack mounts, three sets of bottle bosses. The frameset comes with a Fairlight Cempa 100 x 12mm full carbon Fork with 1.1/2″-1.1/8″ tapered steerer.

    Note that the Secan has a 77mm bottom bracket drop, which is lower than most on this list (~70mm). We asked Fairlight about this and they assure us it works for this bike and “it is all the better for it.” So if you are interested in this bike for 650B/27.5″, we’d recommend tires on the heftier end of the spectrum (27.5 x 2.25″), as well as shorter crank arms if you are destined for chunkier terrain where pedal strike is a concern.

    Although Genesis missed the boat by not including mounts on the fork blades, the Fugio looks great in every other way. On the latest iteration of the platform, they added 12mm thru-axles front and rear, full internal Di2 and dynamo routing, three bottle cage bosses on the frame, and asymmetric chainstays for tire clearances up to 2.35″. These improvements are coupled with a solid build kit, including Clement X’Plor MSO 50mm tires, a SRAM Apex 1x drivetrain, and TRP Spyre brakes – a nice combination overall.

The latest model gets a different geometry with a 70mm BB drop, and frame features such as internal cable routing, a Shimano flat mount inboard rear disc caliper mount, and a multi-dropout system; 12 x 142mm with through axle supplied.

    *One issue we have with this bike is the clearances. Although claimed tire clearance has been increased to up 45mm for 700C and 27.5 x 2.0″, it’s unclear whether the Tripster will fit 2.1″ tires as is the criteria for this list. That said, we decided to leave it in as it’s a really interesting frame.

    The newly released Knolly Cache looks mighty interesting. Knolly CEO and Head Engineer, Noel Buckley, wanted a gravel bike that would deliver a ride experience similar to their mountain bikes. He wanted a bike that could go harder and farther.. To differentiate the CACHE, Noel custom designed a titanium bike with a longer front center (similar to their mountain bikes), which when combined with a shorter stem gives the bike MTB handling characteristics. With a massive frame triangle and mounts under the downtube, it looks to have some bikepacking-friendly features too. More details as they’re released.

The 2019 model features WTB dirt-drop handlebars, Brev M. 23mm IW rims, a wide-range 3×10 Deore drivetrain, WTB Nano Comp 27.5 × 2.1″ tires, and plenty of rack mounts.

Bokeh bikes and framesets can use either 650b x 50mm or 700c, with up to 45mm tires. However, as they point out, Bokeh will clear 2.1″ tires, and the fork can take up to 2.25″. The standard Bokeh features a Dedacciai, custom formed, triple-butted Aluminium frame with Mason Parallax full carbon thru-axle fork. It has a full compliment of fender eyelets and a Dynamo light mount at the front. The frame features bottle/accessory mounts on the underside of the down tube, unique Mason MultiPort adaptable internal routing, and rack and mudguard mounts.

    Designed around 29er or 27.5+ tires, with raw brass fillets, a bi-plane, curved offset fork, custom butted tubes, and short telescoping chainstays, this frame is a new take on a classic. According to Cjell MONē, it’s a drop-bar, plus, dirt tourer, born on the Tour Divide. Other frame features include Anything Cage mounts on the fork, two more triple mounts on the frame, and fender and low rider rack mounts. It’s non-suspension corrected, “a true dirt drop miracle designed to take on a grocery run, or a run down the Continental Divide.”

    Note that with a full 29+ setup, some toe overlap can be experienced on the S/M frames. As such, 27.5+ wheels are a great option for this bike. Also, with a 75mm bottom bracket drop, anything smaller than 27.5 x 2.4″ tires might make the bottom bracket a little low for those venturing into rugged and uneven terrain.

At Interbike 2016, we got to take it for an hour long spin on road, gravel and singletrack. Built around a technology-laden carbon frameset with a superlight spec, it felt quick to ride, and incredibly easy to shoulder, though its quick handling felt a little twitchy until we were used to its geometry. It’s definitely a bike with lots of potential, not least because it’s drawn to take both 700C road wheels, or 650B mountain bike rubber up to 55m (2.2″) wide.

Its frame is designed around 650B gravel or mountain bike tires up to 2.4″ wide and can also run 700c x 46mm rubber. OPEN claims dropping both chainstays not only offer up more tire clearance but also improves bottom bracket stiffness and reduces overall weight. A dropped drive-side chainstay is a familiar sight in the gravel bike world, which OPEN surely takes some credit for, but dropping both down is certainly something far less expected.

    A.L.I.C.E. has a super high BB (55mm drop), so it should work fine with smaller 650B tires as well.

  • Rivendell Atlantis

    Rivendell Atlantis

    • frame/fork: Steel/Steel
    • Max Tire Size: 29 x 2.2" (59-62cm frames) / 27.5 x 2.2" (47-56mm frames)*
    • Bottom Bracket: 68mm Threaded
    • Dropouts (F/R): 100/135mm QR

    The Atlantis was renamed from the original Rivendell All-Rounder, a bike built for big tires and fire-roads. The original was made in batches of three in Wisconsin. Later, the Atlantis was fabricated in Japan in larger numbers, but the costs went up. To keep the same quality and maintain a competitive price, the company moved production to a trusted facility in Taiwan. The Atlantis still has the same creamy blue-green color scheme and headbadge, and underneath, the investment-cast Rivendell lugs and custom drawn Silver tubes are all the same. Such a beauty. Make sure to check out Benedict’s musings on it here.

    *Note that Rivendell switches wheel sizes with frame size: 47-56mm frames are 650B and 59-62cm frames are 700c.

    • Max Tire Size: 27.5 x 2.2"
    • Bottom Bracket: 68mm Threaded
    • Dropouts (F/R): 100/135mm QR

    Priced at $899 or $1,099, depending on the model, the new Journeyman rounds out Salsa’s multi-platform, all-road lineup, landing on the entry-level end. It seems as if the Journeyman is designed for gravel-curious riders who aren’t quite ready to pony up $2,500 or more for a race-ready Warbird, but are looking for a feature-rich, versatile bike. Built around an aluminum alloy frame and either a 2×9 Shimano Sora or 2×8 Claris drivetrain, the Salsa Journeyman comes with 650B x 2.1″ or 700C x 37mm tires, drop or flat bars, and either a carbon or alloy fork. All told, there are six models. View the full specs here.

    Inspired by the Pamir Highway – traversing Central Asia’s Pamir Mountains – the new Pamira from UK-based Stanforth Bikes is built for loaded riding off the beaten path. And like all of Stanforth’s bikes, the Pamira is handmade to order in the UK and can be tailored to your measurements at no extra cost.

    The frame features bosses for front and rear racks, four bottle cage mounts, fender mounts, as well as three-pack bosses on the fork. It has routing for both Rohloff and derailleur gearing with dropout inserts for easily switching between the two. The Pamira is built from a mix of heat treated Reynolds 853 and 725 steel in the main triangle and air hardened 631 in the rear triangle. It’ll clear up to a 27.5” x 2.4” or 700c x 2.2″ tire.

    • Bottom Bracket: 68mm Threaded
    • Dropouts (F/R): 12 x 100mm / 12 x 142mm

    The Surly Midnight Special is a Road Plus bike designed to provide comfort and speed on all-day rides that extend well beyond fresh pavement. The Midnight Special has fewer features than other Surly models, but it utilizes modern road standards like flat-mount disc brakes, 12mm front and rear thru-axles, and a 44mm head tube. Coupling all that with a 650B x 60mm or 700C x 42mm tire clearance and a road-oriented geometry, they’ve come up with a very interesting bike. It has mounts for racks, fenders, and three water bottles as well.

    built in Bristol, UK, the Temple Adventure disc is designed around 700C x 35mm tires, but will accommodate 650B x 2.1″ rubber, according to readers and their internal team. The Temple Adventure disc features handbuilt Hunt 4 Season Gravel Disc Wheels, a Reynolds 725 steel frame, a glossy powder-coat finish with internal e-coat protection, TRP Spyre Disc Brakes, a Brooks B17 saddle, and Shimano 105 gearing.

    While we normally wouldn’t include a complete-only bike with 700c wheels in this list, it came recommended from a couple different people, and we thought it was a worthy inclusion.

  • Velo Orange Polyvalent

    Velo Orange Polyvalent

    • Frame/Fork: Steel/Steel
    • Max Tire Size: 26 x 2.3" (w/fenders) / 27.5 x ?
    • Bottom Bracket: 68mm Threaded
    • Dropouts (F/R): 100/135mm QR

    As its name suggests—French for “many forms”—Velo Orange positions the Polyvalent as a do-it-all frameset: porteur, randonneur, tourer, or mixed terrain racer. The Polyvalent’s low trail geometry is suited to a front load, so that it holds a line well both loaded and unloaded. The newest iteration of the Polyvalent takes disc brakes with increased tire clearances. Throw on 650b tires for general use or some knobby 26″ tires for a gravel adventure. While we are a little unsure whether it fits our criteria (27.5 x 2.1″ tire), we think it does as VO states that it clears either 650B x 47mm or 26 x 2.3” tires with fenders.

    The Polyvalent is loaded with water bottle mounts: triple on top of downtube, one set on seattube, one set on underside of downtube, and a triple on each fork blade. It also has fender mounts and double eyelets on rear dropouts for racks and fenders.

    The Veloci Jimmy features a Columbus Cromor frameset with a drive-side yoke that allows tire clearance up to 27.5 x 2.25″ or 700 x 45mm (although there are also claims that it can squeeze 2.4s). Jimmy has plenty of mounting options, including three-pack cage mounts over and under the down tube, top tube bag mounts, provisions for a rack and fenders, and another bottle cage pair on the seat tube. Other frame features include a STEEL RULE SUPPLY investment cast dropout that can toggle between quick release and 12mm thru-axles, stealth dropper post routing, and a BSA threaded 68mm bottom bracket shell. The Veloci Jimmy frame comes standard with a VELOCI No.11 carbon fork, complete with triple cage mounts on both legs, a flat brake mount, and a 12mm thru axle.

What’d We Miss?

We searched high and low to gather a comprehensive list of 650B gravel bikes that fit our criteria. However, we’re well aware that we probably missed a few. If you know of a bike you think will make a solid addition to this list—preferably one you have first-hand experience with and can recommend—please let us know in the comments below. Please note that we aren’t as interested in bikes devoid of extra bottle mounts; we also only list bikes that are available to purchase/order and have an informational page published on the web. Additionally, there are some bikes sold with a 700c kit that may work setup as a 27.5″. We may publish these if they are available to purchase as a frameset.

In addition, more 27.5″ drop-bar bikes will be released, and some of the models here will evolve, change, and may even be discontinued. Feel free to help keep this list up to date in the comments. And stay tuned for many more Gear Index lists, including the sequel to this one, 29″ Drop-bar Mountain Bikes.

Also, make sure to check out our article about 700C to 650B conversions. There are a lot of great options out there to use what you already have to create something new using the 650B platform.
