Details

The Altitude from Rocky Mountain is here to push the trail bike envelope. The stiff aluminum frame pushes 150mm of rear travel out of a Fox DPX2 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 Fox 36 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. The Alloy 70 rolls onto the scene with a FORM alloy frame for optimized strength, weight, and ride quality. It brings together crisp power transmission through a SRAM Eagle drivetrain and the precise stopping you get from Shimano XT brakes. Maxxis tires and wide Sun rims provide a remarkable blend of trail sensitivity, tubeless lightweight, 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.
