The Cube Reaction C:62 PRO Hardtail Mountain Bike - 2027 is a light and fast cross-country bike built for efficient riding and precise control. Its C:62 carbon frame keeps weight low while retaining strength in key areas. A 100mm RockShox SID SL Base air fork manages rough ground, while Shimano XT 12-speed shifting and XT hydraulic disc brakes provide dependable control. Newmen Performance 30 wheels and fast Schwalbe Racing Ray and Racing Ralph tyres complete the race-focused build.Key Features and Benefits:C:62 Carbon Frame: CUBE uses a high level of high-modulus carbon fibres within its C:62 material. Advanced Twin Mold construction controls the position of these fibres during production. This allows material to be placed where strength is needed while reducing excess weight. The result is a stiff and light frame that transfers pedalling effort well and helps the complete bike weigh just 11kg.RockShox SID SL Base Air Fork: The 100mm SID SL Base fork uses an adjustable air spring, so its support can be set to suit rider weight and preference. The OneLoc remote lets you control the fork from the handlebar. This helps reduce unwanted suspension movement on smooth sections while retaining effective suspension for rougher ground.Shimano XT 12-Speed Drivetrain: The XT RD-M8200-SGS rear derailleur works with a wide-range 10-51T cassette and Shimano Deore 32T chainset. Its broad gear range gives you lower ratios for steep climbs and harder gears for faster sections. Shimano's Shadow Plus design also helps control chain movement on rough trails for more consistent shifting.Shimano XT Hydraulic Disc Brakes: XT BR-M8200 hydraulic brakes provide strong and progressive braking through 180mm front and 160mm rear rotors. Hydraulic operation gives you precise control over braking force with less effort at the lever. This makes it easier to manage speed on fast descents and maintain control on technical ground.Newmen Performance 30 Tubeless Ready Wheels: The light Newmen wheelset uses Boost hub spacing, with 15x110mm at the front and 12x148mm at the rear. The wider hub layout supports a stiff wheel structure for accurate handling under load. Tubeless-ready rims also give you the option to reduce puncture risk and run lower tyre pressures when set up with compatible tubeless equipment.Schwalbe Racing Ray and Racing Ralph 2.25in Tyres: A Racing Ray front tyre is paired with a Racing Ralph rear tyre, both using Schwalbe's Addix Performance compound. The front tread focuses on steering grip, while the rear balances traction with low rolling resistance. This combination supports quick acceleration while keeping dependable grip through corners and on loose ground.The Reaction C:62 PRO is designed around efficient cross-country performance. Agile Ride Geometry keeps the steering responsive without making the bike unstable at speed. The Boost rear end adds stiffness, while the UDH derailleur hanger makes replacement easier and supports modern drivetrain standards. It is also dropper post ready, giving you a clear upgrade route if you want more control on steep or technical trails.For fast cross-country rides, training and racing, the Cube Reaction C:62 PRO brings together a low-weight carbon chassis and a well-matched set of proven components. Its combination of efficient power transfer, controlled suspension and precise braking makes it a strong choice for riders who value speed without giving up practical trail control.Size Guide:X-Small: 4'10" - 5'2"Small: 5'2" - 5'6"Medium: 5'6" - 5'10"Large: 5'10" - 6'1"X-Large: 6'1" - 6'4"
