They take the "Pro" label seriously. So they started with a very light but stiff carbon frame and added some of the best components they could find, including a 2x11 Shimano XT drive group. The Reaction GTC Pro is the weapon of choice for everything from fast trail blasts to flat-out racing - in both 27.5 and 29 inch versions.
You can expect a peerless carbon frame from the Reaction GTC - it was created with the innovative twin mould technique. Fastidious design details like the large tube profiles, tapered head tube, PressFit bottom bracket shell and X12 quick release axle at the rear combine to create a balanced, efficient and precise chassis which is also extraordinarily light. And, although it's very stiff, it won't beat you up thanks to the 27.2mm diameter seat post. Neat touches include internal cable routing and the chainstay-mounted disc brake mount. Agile Ride Geometry is part of the total package, delivering precise handling even on narrow, twisty singletrack.
With the 100mm travel RockShox Recon Silver suspension fork's remote lockout, tapered steerer and 15mm QR axle there's no excuse for not attacking even the most challenging of trails.
And Magura's MT4 hydraulic disc brakes are powerful and predictable in all weathers, scrubbing speed from the light and stiff Answer Attach AM wheels whenever the need arises.
Shimano's 2x11 XT gear components and wide-range 11-42 cassette offer reliable gear shifts and optimal power transfer, whatever the conditions.
Press Fit BB
With Press Fit bearings, the bottom bracket bearings are pressed directly into the frame and not screwed in as usual. This gives a wider bottom bracket shell and allows us to build a wider down tube and more broadly-spaced chainstays. Every millimetre of additional width gives a significant improvement in lateral stiffness.
Adaptable X12 Hanger
Cube optimized their new dropout design based on the Syntace X12 through-axle system, enlarging the area of the frame where the hanger is mounted. They 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.
