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.


Frame: The Reaction GTC twin mould 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 27.2mm seat post offers added comfort, while the Direct Mount derailleur system, front mech design and internal cable routing are all state-of-the-art. Agile Ride Geometry offers maximum riding fun, control and comfort rolled into one. .


Features: The Reaction GTC with Manitou's 100mm 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 180mm 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 &ælig;ffect SL double chainset (36/26) 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.
