Rocky Mountain

Fusion 40 Bike 2022

What Our Gearhead® Experts Are Saying:

"This is the bike I recommend when someone wants one hardtail that can handle singletrack, forest roads, and a bit of everything. The Judy fork and SRAM SX drivetrain deliver great value. Geometry is spot-on for both control and fun—especially with 29in wheels and a slack front end."

The Rocky Mountain Fusion 40 Bike is built for riders chasing adventure across a variety of terrain. Its 6061 alloy frame features downcountry-inspired geometry updates—longer reach, slacker head tube, and a lower standover—for modern trail confidence. Combined with big 29in wheels, the platform is responsive and efficient, yet stable on descents and tight sections.

RockShox’s Judy Silver TK Air fork provides 100mm of bump absorption with a Fast Black coating for durability. SRAM’s SX Eagle drivetrain delivers smooth 1x12-speed shifting and a wide 11–50T cassette for tackling steep ascents. Clarks M2 hydraulic disc brakes offer consistent, reliable power on the way down. WTB i30 rims and Ranger Comp 2.4in tires add both cushion and grip, and the tubeless-ready setup is ideal for those ready to upgrade.

The Fusion 40 excels as a one-bike solution for riders who want the lightweight speed of a hardtail without giving up trail capability. From long XC loops to flowy singletrack and weekend missions into the backcountry, it’s tuned for every type of trail you’re ready to explore.
