Rocky Mountain Altitude Alloy 50 27.5″ Bike 2022
The Enduro Racer and Aggressive Rider
Mountain bikes are more capable than ever before. They are able to conquer rocky descents and steep climbs all while having longer and more efficient travel. The Rocky Mountain Altitude is Rocky Mountain’s key platform for enduro racing and aggressive trail riding. It has been redesigned to be competitive on today’s racetracks while still being a ton of fun for the weekend warrior. The Altitude features a wheel size split on the medium frame with the small and medium frame coming with 27.5″ wheels and medium and up frames coming with 29″ wheels. The FORM alloy frame features internal cable routing, 2-bolt ISCG05 tabs, and RIDE-9 adjustable geometry so you can dial in your ride to your style of riding.
The Alloy 50 version of the Rocky Mountain Altitude comes with a Shimano SLX/XT 12-speed drivetrain. This includes a cassette that has a hill-crushing 10-51T gear range that makes climbing and pedaling through demanding terrain much easier. Shimano SLX Trail 4-piston hydraulic disc brakes provide excellent stopping power so you can descend with confidence and control. WTB ST i30 TCS 2.0 Tubeless wheels are paired with Maxxis tires that can be set up tubeless for a smoother ride, better traction, and fewer flats. With the Race Face Aeffect R Dropper Post, you’ll be able to quickly lift and lower your saddle with the press of a lever.
