Cube Reaction GTC SL 29 Hardtail Bike

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.

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.

The 29" wheels allow you to carry high speed over a great variety of terrain.


Next to the Reaction GTC frame, even some pro team race bikes may come up a bit short. Cube has built this chassis to be both light and stiff, by using sophisticated construction with their GTC Twin Mould technique and applying modern technologies like the tapered head tube, Press Fit 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.

The 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.

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.
