The Reaction C:62® frame is made of our proprietary C:62® Carbon using the Advanced Twin Mold process, exceeding all expectations in terms of lightweight, extreme speed, and precise handling. A short rear end with 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 seatpost ensure comfortable seating even on longer rides or when you're pushing hard on the pedals. And with internal routing for cables, maintenance time is saved - getting you back on the trail much faster!
