For This Bike

Rocky Mountain’s Altitude Powerplay can keep up with aggressive riders wanting to push hard yet is equally at home cruising trails under riders who just want to explore and have fun.

The 2021 Rocky Mountain Altitude is an exceptional enduro bike, and I was blown away at how well I got along with it.
Dec 2020 · Mike Kazimer
The new Altitude has a level of versatility that's not always found in an enduro race bike.
Great traction inspires confidence in wet conditions
Very versatile – you don't need to be a pro racer to make the most of it
Lots of geometry adjustments, but they're skewed towards the steeper side of the spectrum
Not the best value when looking at the price vs. parts spec

Rocky Mountain Bikes' 2021 Altitude Carbon 70 29 offers an adjustable ride that handles everything from 'long-travel trail' to 'full enduro'.

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.

The ultimate enduro-race-ready mountain bike with unlimted adjustability. Passengers, look elsewhere.

Because the weight of the motor and battery is located centrally and low down, the bike is fairly stable and confident at speed, despite being a little short by modern standards.
