The Altitude Carbon is purpose-built to go fast and demolish steep trails. Fine tune your ride by opting for full 29'' or MX, using the built-in flip chip (sizes MD-XL) or adjust the RIDE-4™ with a single Allen key. Its total enduro capabilities can help you secure that “top step” and own those demanding group rides with confidence. The redesigned Altitude Carbon also features internal routing and the new PenaltyBox™ 2.0 downtube storage. With so much capability in your corner, it’s time to push limits, climb faster, and charge. Enduro lives at Altitude.

Size Specific Tune

Size Specific Tune ensures that riders of all sizes get the right balance of small-bump compliance, mid-stroke support, and end-stroke progressiveness. Our design team does custom shock tunes based on real-world field testing and adjusts each tune for specific frame sizes. The new Altitude also has size-specific chainstay lengths to offer a balanced ride across all frame sizes.


Smoothwall carbon uses one of the world’s most sophisticated carbon processes to deliver industry leading stiffness-to-weight, ride quality, and durability.
