Frame: Our engineers threw everything they know about carbon frame technology at the Reaction GTC One12's chassis. That's why it's built with our stiffness-enhancing, weight-reducing Twin Mould technology and incorporates internal cable routing for cleaner looks and longer cable life. Our acclaimed Agile Ride Geometry brings the nimble handling of smaller wheeled bikes to our 27.5 and 29in range, while X12 dropouts keep everything tracking straight and true and the 27.2mm seatpost adds welcome comfort, even on long rides.
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.
