Smoothwall carbon uses one of the world’s most sophisticated carbon processes to deliver industry leading stiffness-to-weight, ride quality, and durability.
The two-position axle allows the rider to choose a short or long rear-center length that suits their personal preferences.
The RIDE-4 adjustment system allows riders to quickly fine-tune their geometry with a single Allen key. Four configurations are possible thanks to one rotating chip.
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 PenaltyBox™ 2.0 downtube storage (carbon models only) includes generous capacity, custom tool wrap and our rock-solid hinged door system that doubles down as a water bottle mount and built-in concealed AirTag/Tile compartment.
Fine tune your ride with center, +/- 5mm offset options.
