Overview
About this bike
Our most high-tech Stealth Alloy frame ever deserves nothing less than the best. The RR build is a step up if you want to get even more out of your SLY. FOX suspension provides the 160mm Fox 36 29 Float Performance GRIP fork and a Fox Float X Performance EVOL shock. SRAM Code Bronze Stealth 4-piston brakes with 200mm rotors keep things from getting out of hand on the steeps, and Mavic E-CrossTrail SL 30mm wheels offer the best balance of compliance/rigidity out there. ONOFF has you covered with a selection of components from the all-new S6 range and includes a carbon fibre bar, a stem, grips and the Pija seatpost with lengths varying from 140mm to 210mm depending on frame size. The SLY RR comes in the gorgeous Black / Nimbus Grey / Tonic Gold colourway.
