REACTION HYBRID HPA Pro 400

Frame

Frame: Our aluminium Superlite frame has been updated for 2017, developed specifically to meet the requirements of Bosch's latest drive system and to give the maximum possible versatility. The combination of Optimal Drive Position, Agile Ride Geometry and a carefully sited battery gives the Reaction Hybrid HPA Pro a surprisingly agile ride feel and the most efficient possible drivetrain. Internal cable routing means the looks are as clean as the gear and brake cables. We've even included room to mount mudguards, making this bike perfect for everything from weekend rides to the daily commute. It's also easy to mount a trailer to the dropout - so you could be dropping your kids off at the nursery on the way to the office. Seven frame sizes mean it's easy to find exactly the right one for your height: 14, 16 and 18in come with 27.5in wheels and 17, 19, 21 and 23in are 29ers.

Components

Features: Centrepiece of this bike is the new Bosch CX drive. With up to 75Nm it'll really get you going, even for extended periods of pedalling at higher speeds - useful for tough climbs. The large capacity 400Wh battery has plenty of reserves of power, but you can specify your Reaction HPA Hybrid Pro with the optional 500Wh battery for even greater range. Shimano's 10-speed Deore transmission delivers precise and easy gear shifting with a wide gear range, while the hydraulic BR-M315 disc brakes with 180mm rotors will bring you to a halt reliably, even in wet weather. A comfy ride position is guaranteed by the CUBE cockpit components, while Suntour's coil spring XRC32 fork with remote lockout smoothes things out on even the bumpiest of roads or trails.

      • Agile Ride Geometry

        We ran innumerable tests to develop the Agile Ride Geometry in our series of big wheel bikes. We also added the 27.5in 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.

      • Aluminium Superlite

        Extremely high tensile strength heat-treated 7005 aluminium alloy is developed for the highest requirements. It is very stiff, fatigue resistant, corrosion resistant and has high elongation. Our Superlite tubes are double butted, giving very light tubesets with a high level of stiffness.

      • Onepiece Design

        Welded joints in our high-quality aluminum frames are specially finished via this method and create the impresssion of seamless tube design. This generates the visual effect of moulding and ensures high load bearing capacity.

  • Icon of CUBE technology Tapered Steerer

      • 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.

        The Easy Mount Kick Stand is a new system developed and designed by CUBE. The base of the stand is mounted from below to a fitting plate integrated to the frame and fixed with a through bolt. This kick stand is extremely stiff and solid through the enlarged contact areas between base and frame which gives a stable stand even with loaded panniers.

        The new STEREO , FRITZZ and HANZZ models are built using Advanced Hydroforming. Conventional hydroforming processes cannot achieve these custom shapes and technical advantages. As this manufacturing method reduces the number of welds, the weight is reduced while durability is increased. All

      • Frame Safe System

        To protect our high-end aluminium frames from damage, they are built with the CUBE Frame Save System replaceable derailleur hanger. The mounting thread is in the hanger and not in the frame as usual. In case of a crash, this hanger can be easily and quickly replaced by a new one.
