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.
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.
