The Altitude from Rocky Mountain is here to push the trail bike envelope. The ultra-stiff frame pushes 150mm of rear travel out of a Fox DPX2 Factory shock and features RM’s RIDE-9 interlocking chip design, allowing you to easily dial-in suspension characteristics to tackle any terrain — from technical BC loam to clapped out enduro tracks, flowy New Zealand jumps, and Moab slickrock. Aim the legendary Fox 36 Factory fork at the gnarliest descents and wheel-sucking ruts you can find. At 160mm, it’s built for brutality while delivering Fox’s sophisticated damping to keep you on rails through the risky line.

Rocky Mountain spec’d the Altitude to expand what is possible on any trail, no matter what price point fits your budget, and the Carbon 90 pulls out all the stops. Of course, the C90 benefits from the industry-leading stiffness-to-weight delivered by its highly refined Smoothwall carbon frame. It also boasts the undeniably smooth, light, and now massively geared Shimano XTR 12-speed drivetrain to get you where you’re going without fail. The excess speed you’ll generate is handled easily by a pair of downhill-ready Saint brakes, willing and able to perform consistently on your longest, most harrowing descents. Maxxis tires and Race Face ARC 30 rims provide a remarkable blend of trail sensitivity, tubeless low weight, and gravity-savvy traction so you can find the ribbon of terra firma that thrills you, hit the dropper remote, and tear straight into the dream.

The RIDE-9 adjustment system allows riders to quickly fine-tune their geometry and suspension with a pair of Allen keys. Nine configurations are possible thanks to two interlocking chips. Position 1 geometry configuration shown below.
