ES 2023 Rocky Mountain Fusion
The best trail adventures happen on the Fusion.
The 2023 Rocky Mountain Fusion is a versatile hardtail mountain bike made for pathways, singletracks, trails, and beyond. You can explore public places known to all cyclists, and local hidden gems off the beaten path. Anything is possible with the amazing combo of efficiency, capability, and reliability. It's equipped with 29" wheels and wide 2.4" tires for trail adventures.
A 1x drivetrain gives you a wide range of gears for climbing and descending. It's also more aerodynamic because no front derailleur or shifter, and one less chain ring.
