When you leave the rest behind on the GTC SL, it'll be clear why. There's simply no serious competition for this standard-setting racer, whether in 27.5in or 29er wheel options. In either case, the GTC carbon frame with high performance, lightweight components - a complete XT group and new Fox 32 Float Performance SC suspension fork - is the ideal bike for cross-country, marathon racing or just epic day rides.
Next to the Reaction GTC frame, even some pro team race bikes may come up a bit short. They've built this chassis to be both light and stiff, by using sophisticated construction with our GTC Twin Mould technique and applying modern technologies like the tapered head tube, PressFit bottom bracket and an X12 quick release axle. The slim 27.2mm seatpost adds a little extra comfort and, with Agile Ride Geometry (ARG), there's no compromise in the handling department.
Consistently perfect performance - even in bad weather conditions - is what the 2x11 Shimano XT transmission and powerful, accurate XT hydraulic disc brakes are all about.
Exceptionally light Fulcrum Red Power wheels with 23mm rims endow the GTC SL 2X with blistering acceleration. Contact points blend performance and comfort - they include the Selle Italia SC1 saddle and a CUBE cockpit designed for optimum ergonomics.
The new-for-2017 Fox 32 Float Performance SC suspension fork with 100mm travel features a handlebar lockout and provides smooth, controlled bump absorption without wasting any of the rider's energy. Even better, new cast lower legs mean a substantial 200g weight saving without sacrificing strength or steering accuracy.
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.
