The perfect cross country fork upgrade, the 2016 Rock Shox SID RCT3 Solo Air 100 29 Inch Fork Tapered 15mm offers excellent stiffness, control, & plushness to maximise your speed over fast, flowing trails. With its lightweight focus, the SID is ideal for racing weighing between 1355g (26) to 1630g (29). Power Bulge technology helps to keep this weight low by removing the need for large stanchions through the use of reinforced areas on the fork lowers. The Solo Air damper of the SID fork provides consistent performance with easy adjustment via the single schrader valve which fills both the negative & positive air chambers at the same time to ensure equilibrium for maximum performance.
