The 2021 Rocky Mountain Solo, their adventure gravel bike, was recently updated with new colours, builds, and prices. Find all the details here…

The Rocky Mountain Solo, which we reviewed last year, is a drop-bar gravel bikes that naturally fills the gap between skinny-tired road bike and knobby-tired mountain bike. It’s a great option for exploring paved roads and gravel with the occasional trail mixed in. Although the frame design and features all remain the same for 2021, Rocky Mountain recently announced new paint jobs and build kits. It appears Rocky is veering away from the 650b Solo, which originally had clearance for 650b x 2.2″ tires, and sticking with skinnier 700 x 40 / 37mm tires for both builds, essentially becoming even more road-like.

2021 Rocky Mountain Solo 30

The Solo 30 is the more affordable build in the line, built up around a SRAM Apex 1 drivetrain, TRP Spyre mechanical brakes, and Schwalbe G-ONE 700 x 38mm tires. It has a clean all-black paint job, the same 6061 SL Series Alloy frame and carbon fork, and retails for $1,399 USD.

2021 Rocky Mountain Solo 50

The 2021 Solo 50 remains quite similar to the 2020 model as well. For an additional $500 over the Solo 30, you get Shimano hydraulic brakes, a GRX drivetrain, slightly larger more and gravel oriented tires, and a pretty snazzy two-tone paint job that’s certainly more interesting than all black. The 2021 Solo 50 retails for $1,899 USD.

Head over to Bikes.com or your local Rocky Mountain dealer to get more details and ordering info.

Although the Rocky Mountain Solo I tested last year came with 650b x 47mm tires, all of the features and overall ride quality remains the same for 2021. Read my full review here.
