UPDATED: find our review of the Rocky Mountain Solo 70 here. 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 two models, both featuring a 6061 SL alloy frame with a “Zero Stack” tapered headtube and a 142x12mm rear thru-axle.
- Frame/fork: Alloy/Carbon
- Angles (LG): 71° Headtube, 73.5° Seattube
- Stack/Reach: 613mm/404mm
- BB Drop/Chainstay: 70mm/425mm
- Bottom Bracket: FSA Press Fit BB386
- Hub specs: 12x142mm / 100x15mm Thru-axle
- Seatpost: 30.9mm
- Max tire size: 700x45mm or 650b x 2.2″
- Price: $2549 (Solo 70), $1899 (Solo 50)
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 650bx2.2 tires, as well as a large chainring (each model is specced with a 40t ring). In addition, both the Rocky Mountain Solo 70 and Solo 50 get the same carbon 100x15mm thru-axle fork with triple bosses on each leg. They also share the same Sun Helix TR25 SL 29 rims with Maxxis Ravager EXO TR 700x40mm tires and all the same cockpit components. More details on each below.
As far as the geometry behind the Solo, there are a few familiar numbers. Like the new Trek Checkpoint the Solo uses a drop/swoop stay that ends up at 425mm. However, the Solo appears to have a slightly longer reach and wheelbase, and a slacker front end than other recently released gravel bikes, such as the Trek, Ibis’ Hakka MX and All-City’s Gorilla Monsoon. There is nothing too out of the ordinary, but the longer and slacker Solo might have a slightly different feel.
