With the growing popularity of eyelet-mounted bags and cargo cages, bike tourers and bikepackers are increasingly looking for ways to add mounts to their fork or downtube to attach such accessories. In addition, many desert routes and trips through warmer climates require extra hydration, so mounting extra bottle cages or oversized cages under the downtube, on the fork, or even on the chainstays is often a necessity for supplementing water capacity. These affordable workarounds can also serve to upgrade older bikes for those looking to try their hand at bikepacking but without the cash to invest in a dedicated rig.
Braze-ons, Bosses, and Eyelets
Before moving on, let’s clear up some terminology.
Braze-on, a common term used to reference a bolt mount on a bicycle, is defined as a small fitting on a bicycle that has been permanently attached to the frame. The term comes from how these parts were attached to traditional steel frames. Even though these fittings may be welded onto titanium or aluminum, or glued and molded into carbon, braze-on lives on as a way to describe these mounts. Typical braze-ons include cable stops/guides, rack and bottle cage mounts, or, even more bemusing, bosses.
Bosses are usually interpreted as welded, brazed, or attached protrusions, such as a cantilever brake bosses, rack bosses, shift lever bosses, or even cable guides. However, in the framebuilding parts world, bottle bosses are also very commonly sold as threaded inserts, or as we know them, bottle bosses. All that said, each of these terms is fine and dandy, but since the term braze-on doesn’t always perfectly describe the threaded attachment used for cages and cage-mount bags, we’ll refer to these as either mounts, eyelets, or bosses.
Ultimately, more and more bike frames are being outfitted with extra cage mounts and bottle bosses, especially bikes intended for touring or bikepacking. Provisions often include a pair (or triplet) on the underside of the downtube, as well as a three-pack of bosses on each fork blade (see our Gear Index of Forks with Bottle Cage Mounts). However, some bike companies are still anti “fork warts.” And, many older bikes were relegated to two pairs within the frame triangle. Fortunately, there is an ever-growing list of products made to add cage mounts to your bike with various connection techniques. Find that full product list below, then scroll down to find several DIY methods for adding bottle cages and mounts.

Bedrock Honaker
- Type: Soft Water Bottle Cage
- Made of: X-pac/Rhinotec/Cordura
- Attachment: Velco Straps
- Bottle Size: Nalgene 32oz
CloseWe’re firm believers that every bike should feature bottle cage mounts on the underside of its down tube, bar a few suspended 26ers, where clearance is tight. It’s a no-brainer area for water storage; the center of gravity is kept low, and there’s rarely any interference with terrain or obstacles. Unfortunately, all too many bikes skimp on such potential for water hauling. Bedrock’s Honaker Hydro Pack comes in handy for just such scenarios, designed as it is to hold a 1L Nalgene bottle, via a bag strapped to your bike’s down tube.
The Honaker features with a strip of Velcro sewn in vertically, as well as an adhesive backed strip for the down tube of the bike. This doesn’t act as support, but works to keep the bag from rotating or sliding. There are two main straps that hold the bag in place; each has a rubberized backing material where they make contact, providing a secure anchor point. The spindrift collar is designed to keep the bottle clean, a nice feature when riding in cattle country. It was originally designed to fit a standard 700-800ml water bottle, but now has been updated to fit a larger Nalgene. We tested it using the Zefal 1L Magnum.
We used the Honaker mounted to the Marin Pine Mountain 2 on our trip in southern Spain. It worked flawlessly, and we rode some rough stuff. The only complaint is that it was a little tough to get the bottle in and out without undoing the straps a little. But if you approach it as storage for a backup bottle for camp use, it’s perfect. Overall it’s a ruggedly built product that works well for bikes without down tube mounts.
Highlights
- Works without cage mounts
- Good way to add a bottle or extra storage
- Made by a small company
- Durable
Drawbacks
- Not waterproof
- May not be ideal for fork mounting

DrJ0n Barnacles
- Type: Bottle Cage Mount
- Made of: Plastic, brass, steel
- Attachment: Clamp
CloseThe Barnacle by Drj0n Bagworks provides a low-profile mounting option for bottle and cargo cages on the fork, downtube, or other locations on a bike frame. The Barnacle clamp is 3D-printed from durable plastic and comes in nine diameters ranging from 25.4mm to 47mm, designed to fit commonly available downtubes in steel, aluminum, and titanium, and also rigid steel and suspension forks. You can also use rubber strips to help accommodate varied tubes. For example, 45mm with a 1mm rubber strip fits a Fox 34 or a Fox 36 without.
Each Barnacle uses an M5 bolt and swivel nut to secure it to the tubing and a brass M5 threaded boss embedded into it. Although they can handle more, Jon suggests loading the Barnacles up with no more than 1,000 grams will have negative effects on the bike’s handling (when mounting to the fork), and should be avoided. Find more at our press release here.
While we haven’t tested the Barnacle specifically, we have put some miles on the DeWidget G-Funk Clamps, which are the same design and we have no problem vouching for their performance and reliability.

King Cage Universal Support Bolt (USB)
- Type: Bottle Cage Mount
- Made of: Stainless Steel
- Attachment: Clamp
CloseThe stainless steel King Cage USB (Universal Support Bolt) is a versatile solution for bikes without bottle cages, or suspension forks. Generally speaking, we’ve been impressed by the build quality and thought that King put into these little gadgets. Since our first test, which went relatively well, the USBs have been redesigned. This is a welcome change since we had a couple break when not properly tightened. The updated versions shown here include a beefier post mount area which looks bombproof. We’ll update our review with more feedback once we put them through the wringer.
Considering that many new bikes are missing a pair of bottle bosses under the downtube, and there’s no such thing as a suspension fork bottle mount, the USB is a good option. It comes in four sizes: 1 1/8-inch for handlebars and seat stays, 1 3/8-inch for steel frames and forks, 1 5/8-inch for 32mm suspension forks, and 2-inch for aluminum tube bikes and 36mm suspension forks. Note that because the cage attaches via a post mount, the nut goes onto the cage and some bottle cages might not work if they don’t have a recessed channel.

Revelate Designs Joey Downtube Bag
- Type: Cargo Bag
- Made of: X-Pac
- Attachment: Velcro Straps
- Volume: 2L
CloseThe Revelate Designs Joey attaches under the down tube on most any bicycle, just above the bottom bracket. Requiring only two velcro straps to attach, the Joey provides a viable solution for adding gear or water storage capacity to bikes without mounts at that position.
A layer of stiff foam against the back of the bag gives it structure and some padding when strapped to your downtube, and it’s covered in a grippy rubber material and shaped to hug cylindrical tubing. It’s constructed from VX21 X-Pac and uses a standard roll-top closure to avoid dealing with dirt covered zippers.
The compression molded dual density foam used in the contact panel provides just the right amount of structure to this bag, and the rubberized outer material paired with the silicon-coated straps do an excellent job of keeping it in place. For bikes without bottle mounts under the downtube, the Joey offers a nicely designed solution for adding a little bit more storage, for either gear or water.
Highlights
- Enables down under storage on bikes without downtube mounts
- Doesn’t slip due to well-engineered, molded foam contact area and silicone-coated straps
- Well sized for larger items; perfect for cook kit/Vargo BOT
Drawbacks
- Only comes in black
- Fixed strap placements might be limiting on some bikes
- Velcro straps may wear out over time

Rogue Panda Bismarck Bottle Bucket
- Type: Handlebar Bottle Cage
- Made of: Cordura/plastic/etc
- Attachment: 3 Voile Straps
- Bottle Size: Standard Bottle
CloseNamed after Bismarck Lake, a water source off of the Arizona Trail north of Flagstaff, the Bismarck was completely redesigned in spring 2023 to be more secure and even easier to use. It features a Voile strap fork crown and handlebar attachment, it can be mounted on either side of your stem, and they’ve added exterior mesh pockets on the three rider-facing sides of the bag. It’s easily the highest-capacity stem bag available that we’re aware of. Miles likes it so much that he included it in his Summer 2024 Editor Dozen gear picks.
Highlights
- One of the most stable, wiggle-free feed bags
- No stem strap required
- Securely holds a standard cycling bottle with no cinch or drawstring required
- Competitively priced
- Handmade in USA

Tailfin SFM (Suspension Fork Mounts)
- Type: Bottle Cage Mount
- Made of: Carbon, Rubber, Steel
- Attachment: Clamp
CloseTailfin Suspension Fork Mounts – or SFMs for short – allows bikepackers to attach either two water bottle cages per fork leg, a water bottle and cargo cage combo, or any other variation. Two stainless steel button head bolts are also provided per SFM mount, covering you for two cages per side. And each set includes two mounts, which is enough for one fork leg. There are even two versions of the SFM available. One weighs just 82g per pair and uses a carbon fibre band, while the other tips the scales at 128g and is made from stainless steel.
The SFM clamps onto the fork using an a bolt and swivel-nut. Each ships with three rubber ‘chips’ of differing thicknesses, along with three bolts of differing lengths (20-35mm long), allowing proper sizing for a variety of forks. There’s also a nice instruction sheet and measuring bar that makes installation simple. You can find detailed rundown in our review.
While they’re not cheap, Tailfin has created a product with a high level of design, engineering, durability, and finish, and until you actually handle them and fit the SFMs, it’s hard to convey how well made they actually are. We think the SFM is perhaps one of the better and more elegantly designed options we’ve tried for use with a suspension fork. Logan and Virginia recently put nearly 2,000 miles on four pairs in Baja and Oaxaca, with no issues to speak of.

Wolf Tooth B-RAD Bases
- Type: Bottle Cage Mount, Alt Position
- Made of: Aluminum
- Attachment: Bolt or Zip Tie
CloseShort for Bottle Relocation and Accessory Device, B-RAD was created to expand and maximize the potential of your bike’s preexisting bottle mounts. The system consists of three different machined 6061-T6 aluminum mounting bases—the B-RAD 2, 3 and 4—and a growing number of mountable accessories. Each base has several bosses and multiple cage locations, as well as a sliding slot mount to attach to your bike’s existing bosses. Among many other specific uses, each base can shift a bottle cage away from rear shocks, add room for tools or spare tubes below a bottle cage, or even provide space for a second bottle (or double bottles) on sufficiently long downtubes. In addition, Wolf Tooth provides rubber pads and zip ties so that the B-RAD bases can be attached to a bossless fork blade, suspension fork, or downtube.

Adventure Hydration Cage Mount Adapter
- Type: Bottle Cage Mount
- Made of: Plastic
- Attachment: Hose Clamps
CloseFrom Adventure Hydration: “The Cage Mount Adaptor is a simple way to provide a mounting solution for all types of cages to fork legs, down tubes etc. Sure, they’ve been done before, but what is different about this ours is the V section underside which provides two lines of contact and so greater mounting stability. The Cage Mount Adaptor uses the same robust additive manufacturing process that is used for our Cranktank4 Caps, Tube Keepers and Wedgie. In fact, two prototypes have travelled both the GDMBR and the Tour Aotearoa. We prefer utilising stainless hose clamps to secure these to the bike but, equally, the old simple method of cable ties and self adhesive tape will do the job too. It includes: 1 Cage Mount Adaptor, 3 x 5 mm x 16 mm bolts plus washers and nuts, 1 Self Adhesive Rubber Strip”

Paragon Machine Works 2h2o Mounting System
- Type: Bottle Cage Mount, Alt Position
- Made Of: Aluminum
- Attachment: Steerer Tube
CloseDesigned by Luis Lopez, a Machinist and Product Designer at Paragon Machine Works in California, the 2h2o Mounting System is a unique dual bottle mount that fits nearly any type of bike. The 2h2o Mounting System attaches to the bike’s steerer tube, taking the place of a stem spacer, and has two adjustable arms that allows for the mounting of two standard bottle cages or compatible cargo cages. Paragon says it’s designed to be “enjoyed within moderate riding conditions”, so we’re not sure how it well it would hold up on rough singletrack or bumpy terrain.
It uses a pin and slot design for linear and rotational adjustments so that mounted items can be optimally placed to maximize knee clearance and handlebar turning radius. It is machined in California from 6061 Aluminum, is rated for 2lbs per cage mount, and looks like it could be a clever solution for those with limited bag space or a cramped cockpit.

Adding Permanent Bottle Cage Mounts to Your Frame
If you aren’t up for clamping, strapping, or taping mounts to your frame, there are two ways to permanently add bottle bosses to your frame or fork.
Hire a Framebuilder
While it’s possible to have a carbon expert drill and glue bottle mounts in a carbon frame, and there’s likely a way to weld in bosses on an aluminum frame, both of those scenarios get pretty complicated. We won’t even get into it. However, if you have a steel frame, it’s pretty straightforward. We had bosses added to the underside of two v1 Surly Trolls’ downtubes (before they became a standard feature). It works like a charm and doesn’t cost too much. However, framebuilders are a busy lot, so you might have to wait. In addition, when deciding where the bosses are going to go, consider tire clearance when your suspension fork is compressed, if you run one. And, realize that brazing will damage the finish on your bike, which might require a repaint, or at least a partial respray.
Rivnut Bottle Bosses
“Rivnuts,” also known as rivet nuts or threaded rivet inserts, are one-piece, internally threaded tubular rivets that can be anchored from one side. To clarify, a rivnut attaches by way of a threaded tool that compresses it, buckles one side, and clamps it onto the panel into which it’s being riveted. If you don’t mind drilling your fork or frame, this is a good solution that can be implemented for a fairly reasonable price. We did it on a Surly Troll and rode it thousands of miles with no issue. Read about the process here. Note that one advantage to Rivnuts is that they don’t require a respray, but the disadvantage is they could rattle loose. Also, this process is best done on burly forks rather than ones that are lightweight and slender.
Attaching Bottle Cages to Your Bike (DIY)
In this Bikepacking Hacks video, Neil discusses the importance of mounts and cages and demonstrates six DIY methods of adding them to your bike. Watch that below and scroll down for a list of DIY methods
Hose Clamp Bottle Cage
Hose clamps (aka pipe clamps) are the most common method used to attach bottle cages onto suspension forks or a boss-less metal bike frame. We don’t recommend this method for a carbon fork, although we’ve seen it done with padding and a light touch. Hose clamps are measured in diameter, so you’ll need to calculate the tubing size plus the cage you’re clamping; I typically use a 3.0″ clamp on a fox 34 or RockShox fork (common suspension forks have a 1.75″ diameter) sandwiching a layer of recycled inner tube or electrical tape to protect the tubing. Tighten it enough to hold the cage in place (but not too tight on a suspension fork). Note that some cages work particularly well for this. Widefoot’s oversized cage has strap slots and Salsa’s Nickless Cage has slots through which the straps can be threaded. Others have tabs. With some cages, you might need longer pipe clamps to strap around the tubular rails.
Electrical Tape Bottle Cages
First seen in our list of Bikepacking Hacks, electrical tape is probably the safest and most trustworthy method of attaching standard bottle cages to a fork, downtube, suspension fork, or just about anywhere, even on oversized tubes. For a secure mount, use about 2/3 of a roll of electrical tape. The Lezyne Power Cages work great for this. To protect your frame, first apply a little tape where the cage will make contact. The cage shown above lasted close to 1,000 miles while bikepacking and trail riding all over the rugged southwest, and it was removed before showing any signs of wear. The great thing about electrical tape is that is comes off easily without residue.
Zip Ties and Tubes
Although this is our least favorite method for attaching a bottle cage to a fork or downtube, it can work with the right zip ties and appropriate load. While zip ties are strong, they’re not as strong as metal straps, and they have a tendency to dry rot and wear down over time. Either way, this method works. Use the beefiest zip ties you can find, and like the pipe-clamp method, sandwich cut pieces of recycled inner tube between the cage and tubing to prevent slippage and abrasion.
Voile Straps
Voile straps are highly useful for bolstering large water bottles in more flimsy cages, especially on very rough terrain. However, strapping a cage onto a frame with Voiles is also doable. You can do it with some cages that have slots big enough to fit the straps. Or, on oversized cages, you can simply strap on the cage, then strap the bottle to that. It’s a little messy, but doable. Note that it’s better for use with carbon or aluminum oversized downtubes.
Other Hacks
There are plenty of other hacks out there for attaching additional water bottle cages to your bike. Check out this tutorial for adding a carrier to a Tubus rack, and this method for utilizing a rack bolt to mount cages on the seat stay. And, although not really a hack, Bedrock Bags makes the Honaker for attaching a bottle to the downtube. You can also use almost any stem bag as a soft bottle cage.
As with our other Gear Indexes, please let us know in the comments if you are aware of another product or hack to add bottle cage mounts to your bike, or ways to carry an extra water bottle.
