Sporty performance hardtail!
This is where the Formula 1 class of mountain bike starts: with the Reaction. From the stiff but light carbon frame to its high quality features and uncompromising spec, the Reaction GTC is amongst the very best high performance hardtails. It's equally at home blasting trails as it is racing endurance events - in either 27.5 or 29 inch versions.
The Reaction GTC twin mold frame offers everything you'll need from a top-notch carbon frame. Stiffness-enhancing features like the large frame profile, tapered head tube, PressFit bottom bracket shell and X12 axles at the rear combine to offer powerful drive, high steering precision and light weight. The 27.2 mm seat post offers added comfort, while the Direct Mount derailleur system, front mechanic design and internal cable routing are all state-of-the-art. Agile Ride Geometry offers maximum riding fun, control and comfort rolled into one.
The Reaction GTC with Manitou's 100 mm travel M30 offers the perfect blend of comfort and control, with the added advantage of the lowest possible weight. Shimano BR M315 hydraulic disc brakes provide reliable, powerful braking with a 180 mm rotor up front for better cooling on long descents. Shimano's XT 2x11 gear components - including XT Shadow Plus rear derailleur - set the standard for shifting reliability, while the Race Face Aeffect SL double chainset (36/26T) gives this bike an air of exclusivity. The wheelset - featuring durable Deore hubs laced to tubeless-ready Cube EX21 rims - and a performance-orientated but comfortable CUBE Active 1.1 saddle, round out this performance hardtail.

Gran Turismo Composite - In designing the GTC carbon fiber frames, safety and comfort are the main factors. CUBE use high modulus fibers for the parts which are stressed the most the head tube, the seat tube top and the bottom bracket area. That is why the frame still offers flex and comfort resulting from the flexible tubes. CUBE´s special production process with inner and outer molding forms ensure that the minimum of required material is used, reducing overall weight even with complex frame designs. All GTC frames have of course passed DIN - Plus testing.
Twin Mold Technology - The Twin Mold technique uses re-usable cores during the lay-up process to ensure precision frame molding. Special inserts guarantee optimum ply orientation during the production process to add extra strength at frame points subject to higher loads. This improves the safety of the product and delivers outstanding stiffness characteristics.
Agile Ride Geometry - CUBE ran innumerable tests to develop the Agile Ride Geometry in CUBE´s series of big wheel bikes. They also added the 27.5in wheel size to the very well received portfolio. Three important details lead to the very agile character. Increased fork offsets let CUBE achieve the same trail as their 26" bikes without having to steepen the head angle, thus maintaining generous toe clearance to the front wheel. Secondly they shortened the chain stays without compromising the seat angle. CUBE invented a patented construction to mount the front derailleur to give them more tire clearance while keeping a conventional seat angle, leading to a perfect riding position for every rider size. Last but not least they kept the BB height the same as on their 26" bikes. These measures lead to a natural riding position. Every mountain biker will feel immediately at home on a CUBE 29er or 27.5.
Tapered Steerer - This steerer tube design is stiffer than a conventional straight steerer and yields a more secure ride feel even in difficult terrain. Minimal flex at the front of the frame means the greatest possible steering precision. With the larger steerer, the forks become more rigid. At the same time weight is saved due to the absence of bearing shells as the lower bearing is fully integrated into the head tube. On all of CUBE's carbon models the upper bearing shells are also directly in the frame, so that once more a few grams are saved and the energy transfer is very direct.
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 them to build a wider down tube and more broadly-spaced chainstays. Every millimeter 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. CUBE 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.
Integrated Cable Routing - Internally routed cables offer many advantages. Cables are protected from dirt for longer life, weight is saved thanks to the absence of external housing and the bike has a clean, sleek appearance.
