Summary
The Rocky Mountain Altitude is a versatile enduro bike praised for its adjustable geometry, supple suspension, and excellent traction on difficult trails. It excels in descending and rough terrain, though some reviews note it could be more efficient on climbs. The bike's Ride 9 system allows for significant tuning, catering to a wide range of preferences and riding styles.
Adjustable geometry with Ride 9 system
Supple and effective suspension
Excellent traction and stability on difficult trails
Versatile with many spec levels and price points
Clean, fully tubed internal cable routing
Less-than-super-efficient climbing prowess
Overwhelming number of Ride-9 settings
Rear shock requires extra pressure compared to factory recommendations
The suspension feels uniquely supple, fast, and totally unencumbered, soaking up bumps better than Jonny Moseley in his prime.
BIKE MagazineThe Altitude’s leaner looks give you a sense that this bike would be pretty good at climbing and trail rambling too.
BikerumorThis bike was a treat in a lot of different scenarios.

The longest-travel, biggest-wheeled, highest-speed, most capable Rocky Mountain Altitude to date.

Rocky Mountain Bicycles has beefed up its venerable Altitude trail bike for 2021, adding 10 millimeters of travel to the front and back to make it even more capable in the burliest of terrain. The result is a hard-charging bike that can handle steep, technical trails without sacrificing the playfulness and maneuverability of its previous iterations. The 2021 Rocky Mountain Altitude Carbon 70 that we tested is designed to be a do-anything enduro bike, with 170 millimeters of travel in front and 160 millimeters in the rear. It features Rocky Mountain’s RIDE-9 adjustment system, which offers nine positions for the shock mounting point—allowing riders to fine-tune the bike’s geometry to suit their preferences while also making subtle changes to the kinematics of the suspension. I found position three to be the sweet spot for me, as it felt like a great combination of slack geometry for descending confidence without compromising its ability to pedal up steep hills with ease. Climbing up the steep singletrack ascents of Bellingham and Chelan, Washington proved to me just how well the new Altitude goes uphill. With a reasonably steep seat angle of 76 degrees in the short position and a chainstay of 437 millimeters, my front wheel stayed firmly planted on the ground during the steepest of climbs. I positioned my saddle all the way forward on the seat’s rails to make it easier to keep my weight over the front wheel, while also making for a comfortable and stable cockpit that didn’t feel too unwieldy around tight switchbacks. Rocky also seems to have engineered just enough anti-squat into the suspension platform to keep the pedal bob at bay while still providing ample traction during chunky climbs.
