REACTION C:62

Color variants

The Reaction represents something rather special: it's CUBE's Formula One class of mountain bikes. Light, stiff, responsive and built for one purpose only - to go as fast as possible from A to B. To that end, we've poured all our accumulated carbon frame building experience into it. Featuring fast-rolling 29er wheels, the Reaction frame makes use of our C:62 carbon layup and features neat design touches like a Boost 148 rear axle and Stealth dropper post cable routing. Kitted out with a smooth, easily adjustable RockShox air fork, CUBE-built wheelset and a slick, reliable Shimano SLX and XT 2x11 transmission, we reckon it's missing just one vital component: you.

Details

Extracting the best possible performance means sweating every detail. Our design team began with short chainstays and Boost thru axle at the rear, and a tapered head tube up front. The result? Seriously impressive power transfer, steering and overall responsiveness thanks to our Agile Ride Geometry. We haven't forgotten comfort, though - the slender 27.2mm seatpost and slim seatstays work together to help take the sting out of the trail, so you can go harder for longer. Internal cable routing maintains the frame's sleek looks as well as clean gear shifting, and we made sure that an upgrade to a Stealth dropper post is easy. With a PressFit bottom bracket and integrated headset, we've ensured the entire chassis is as light as we could make it. Less, after all, is more. Less weight means more speed...

Technology

      • Advanced Twin Mold

        This technique uses a complete core to provide the perfect frame form during the lay-up process. As with the Twin Mold technology, precise inserts are used to ensure extra strength at high-stress frame points. This combination offers maximum control over fibre orientations during the lay-up and production process. The Advanced Twin Mold high-tech carbon manufacturing process translates to outstanding product safety and quality together with optimum weight and stiffness characteristics.

        We ran innumerable tests to develop the Agile Ride Geometry in our series of big wheel bikes. We 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 us achieve the same trail as our 26in 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 BB height the same as on our 26in bikes. These measures lead to a natural riding position. Every mountain biker will feel immediately at home on a CUBE 29er or 27.5.

        Boost 148mm technology provides precise handling, on every trail, in every situation. The hub flange moves 3mm towards the outside on both sides. It increases the stiffness of a 27.5? wheel by 14% and, for a 29er wheel, by 21%. The reason is the spoke’s wider support in comparison to the 142mm hubs used previously.

      • 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.

      • X12 Through Axle

        In this system, a cone is used to form a play-free connection. It is only necessary to tighten the axle from one side. The position of the wheel is done by an insert in the right-hand dropout which is secured by a bolt. The main advantages of the Syntace system are quick and simple changing of the wheel, reliable position of the brake disc and higher stiffness of the rear of the bike. This allows the assembly to be made lighter than a conventional through-axle.

        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.

      • 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 our CUBE 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.

        On polished, brushed aluminium and all HPC frames, the logos and graphics are applied in multi-layer wet paint. We use this surface treatment technology mainly to save weight.
