Cube Reaction Mountain Bikes

An excellent value for money range of Hardtail XC mountain bikes.

The Cube Reaction has been a firm favourite in the Cube range for a number of years and has been a top seller in the Carbon Hardtail market due to its phenomenal value for money. The Reaction GTC twin mould 29er frame is right at the leading edge of technology. It incorporates every feature needed to improve steering accuracy and efficiency without increasing weight: the tapered head tube, PressFit bottom bracket shell and X12 quick release axles are obvious examples. With a reworked Agile Ride Geometry that blends sublimely efficient forward propulsion with wonderfully intuitive handling, which translates to easy riding fun whether you're on twisty singletrack or a race course. The slimline 27.2mm diameter seatpost offers added comfort.

Twin Mold Technology

Twin Mold Technology

All GTC models are built using this complex manufacturing process. In this process we can eliminate possibly dangerous folding by constant control of carbon fibres during the curing process. By using fixed internal forms at junction points the quantity of resin is considerably reduced and the fibres bonded more tightly together. The result is increased product safety and improved stiffness-to-weight values.

Internally Cable Routed

Internally Cable Routed

Internally routed cables 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.

Agile Ride Geometry

Agile Ride Geometry

We ran innumerable tests to develop the Agile Ride Geometry in our series of big wheel bikes. We also added the 27.5" wheel size to the very well received portfolio. Three important details lead to the very agile character. Increased fork offsets let us achieve the same trail as our 26" bikes without having to steepen the head angle, thus maintaining generous toe clearance to the front wheel. Secondly we shortened the chain stays without compromising the seat angle. We invented a patented construction to mount the front derailleur to give us more tyre clearance while keeping a conventional seat angle, leading to a perfect riding position for every rider size. Last but not least we kept the 88 height the same as on our 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".

Adaptable X12 Hanger

Adaptable X12 Hanger

We optimised our new dropout design based on the Syntace X12 through-axle system, enlarging the area of the frame where the hanger is mounted. We 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.
