The Reaction C:62® frame is made from our specially developed C:62® carbon using the Advanced Twin Mold process and exceeds all expectations in terms of low weight, extreme speed, and precise handling. A short rear end with a Boost thru-axle combined with a tapered head tube and Agile Ride Geometry is responsible for the lively, responsive handling. Slim seat stays and a 27.2 mm seat post ensure comfortable seating, even on longer rides or when you’re pedaling hard. And because the cables run inside the frame, you save time on maintenance – getting you back on the trail much faster!
