Canada’s Rocky Mountain Bicycles began in 1981 and has produced bikes for several disciplines during its 35+ years. The company started with road and mountain bike models and eventually added commuter and cyclocross bikes to its lineup as well.

Long-time cyclocross fans might be familiar seeing Rocky Mountain drop bar bikes at the front of a race. Three-time mountain bike world champion Alison Sydor, who raced cyclocross in the U.S. late in her career, Chris Sheppard, Geoff Kabush and Raphael Gagne all piloted drop bar Rocky Mountain bikes to podiums over the years, and the company even put together special carbon Solo CX machines for Gagne, which we profiled in 2013.

Today, Rocky Mountain Bicycles is best known for its mountain bikes, and if you visited the company’s website (bikes.com, lucky them!) recently looking for a drop bar machine, you would have left feeling flat after looking at all the handlebars—the cyclocross bikes are gone.

In 2018, Rocky Mountain has resurrected the Solo drop bar model bike, and it had reemerged as a do-it-all gravel and adventure bike.

Rocky Mountain offers the Solo in two models: the entry-level $1,900 Solo 50 and the higher-end Solo 70. At a price premium of $650 USD, the Solo 70 upgrades from a SRAM Apex 1 to a Force 1 groupset and shaves off a pound of weight. Both models come with tubeless-ready wheels and wide 40mm Maxxis tires.

Cyclocross Magazine received a Rocky Mountain Solo 50 test bike for grinding some local gravel. Stay tuned for a full review after we take the Solo 50 on some back road adventures.

Rocky Mountain Solo 50

The Solo 50 has a 6061 SL series aluminum frame with a claimed weight of 3.1 pounds and a 1.7-pound carbon disc fork. The flat mount carbon disc front fork has 15mm thru-axles and the rear is 12x142mm. While most companies have moved towards 12mm thru-axles up front on drop bar bikes, Rocky Mountain’s choice of 15mm gives 650b mountain bike owners a better chance of swapping wheels and rotors for a higher-volume ride.

Similar to the Open U.P.P.E.R., 3T Exploro and Ibis Hakka MX, the Solo 50 has a dropped drive-side chainstay for more tire and chain ring clearance and dual wheel compatibility.

The Solo 50 comes built with Sun Helix TR25 SL 29 wheels mounted with 40mm Maxxis Ravager EXO tires. For riders looking for even more volume, the Solo 50 has room for 650b x 2.20” tires. Rocky Mountain told Cyclocross Magazine the chainstays have room for 700c x 42mm or maybe 650b x 2.25″ tires if you want even more volume.

The Solo 50 has a 1x SRAM Apex 1 drivetrain and SRAM Apex hydraulic disc brakes. The FSA crankset and 40t chain ring pair with an 11-speed 10-42t SRAM XG cassette, which is not often seen on with an Apex build.

Rocky Mountain gave the Solo 50 other adventure-ready features to fit the bike’s billing. The handlebar is Rocky Mountain’s wide road drop bar with 12 degrees of flare, the fork and rear frame are both rack-compatible and it also dropper post compatible.

In total, our test bike weighs 22.0 pounds without pedals and has an MSRP of $1,900 USD. The 20.9 pound (claimed) Solo 70 with a SRAM Force 1 groupset has a price of $2,550 USD.

Stay tuned for a full review of the Rocky Mountain Solo 50 bike after we swap out the tubes for sealant, turn off the pavement and put it to the test.

For more, the company produced a video called The Long Way to accompany the release.
