Frame: The Reaction HPA (it stands for High Performance Aluminium) uses a triple butted 7005 aluminium frame manufactured with a complex, advanced hydroforming techcnique. Agile Ride Geometry blends uncompromising efficiency for forward propulsion with lively, playful handling. Every detail has a function. The tapered head tube, X12 axle at the rear and the PressFit bottom bracket shell all work together with the cross-ovalised down tube to provide optimum power transmission, precise steering and phenomenal acceleration. Slender seat stays and the 27.2mm diamater seat post give added comfort.
Adaptable X12 Hanger
We optimized our new dropout design based on the Syntace X12 through-axle system, enlarging the area of the frame where the hanger is mounted. We can now fit the longer Direct Mount hangers. Shifting precision and stiffness is therefore improved. With the new design it's also possible to swap the whole contact area of the axle with the hanger should the system be worn out.
