The 2021 "Reaction C:62 Race carbon’n’white" model from Cube is a high-quality mountain bike that stands out for its advanced technology and first-class specifications. Priced at 2049 EUR, this bike offers excellent value for money for ambitious riders.
The bike’s frame is constructed using C:62 Monocoque Advanced Twin Mold Technology, making it particularly light yet robust. Thanks to the ARG2 design, the tapered head tube and the PressFit bottom bracket, the frame is both stable and efficient. The Boost 12x148mm axles ensure increased stiffness and better power transfer. Furthermore, the frame is ready for a dropper post and features integrated cable routing, giving the bike a very clean overall look. The bike’s total weight is just 10 kg, which contributes to its excellent handling.
For braking performance, the bike is fitted with Shimano XT BR-M8100 hydraulic disc brakes, which, with 180mm at the front and 160mm at the rear, ensure reliable and powerful deceleration. The drivetrain consists of a Shimano XT RD-M8100-SGS ShadowPlus 12-speed rear derailleur, which, in combination with the Shimano Deore SL-M6100-I shifter, ensures precise and rapid gear changes. The drivetrain is completed by a Shimano CN-M6100 chain.
The Fox 32 Float SC FIT4 Performance fork, with 100mm of travel and a 2-position remote lever, offers excellent damping characteristics and can be adjusted as required. The Shimano Deore FC-M6100-1 crankset with 32 teeth and the Shimano Deore CS-M6100 with a 10–51-tooth range offer a wide gear ratio range, suitable for both steep climbs and fast descents.
The Newmen Evolution 318.10 handlebars, 720mm wide, and the CUBE Race SL grips ensure comfortable and safe handling. The Newmen Evolution 318.4 stem, with a diameter of 31.8mm, perfectly complements the bike’s cockpit.
The front tyre is a Schwalbe Racing Ray Addix Performance Kevlar, and the rear is a Schwalbe Racing Ralph Addix Performance Kevlar, both in size 2.25. These tyres offer excellent grip and low rolling resistance on a wide variety of surfaces. The Answer Attack AM wheelset is tubeless-ready and optimally supports the tyres’ performance.
The Natural Fit Nuance Lite saddle and the Newmen Evolution seatpost, with a diameter of 27.2 mm, offer comfort and stability even on long rides. The CUBE Varioclose seatpost clamp, with a diameter of 31.8 mm, rounds off the spec.
In summary, the Cube Reaction C:62 Race carbon’n’white is a lightweight, high-performance mountain bike fitted with high-quality components that performs impressively on both challenging trails and fast rides.
