A new 36mm chassis to deliver exceptional control The SL Super-Light Air system offers small bump sensitivity, mid-stroke supprt, and bottom out resistance at a lower weight than the previous OTT The D1 damper features updated high-flow compression and rebound porting to allow a linear suspension dynamic. This initial damping support without any high-speed harshness paired with a 22% increased volume in the Compression Bladder System results in increased small bump sensitivity and damping consistency High flow linear rebound update increases response without a loss of control or damping A purpose-built crown increases drop for extra down tube clearance and features strategically varied wall-thickness for improved stiffness and strength TECH SPECS model Diamond 36 D1 SL wheel size 29" steerer (stem/race) tapered (28.6/40mm) offset 44mm travel 160mm spring type air brake mount disc only (PM-180) dropout 15x110mm Boost weight 2200g color grey
