Mountain Hardtail
The Pro Series is aimed in equal measure at the pro racer and the hightech enthusiast and represents the counterpart to the HPC Series within our product range, however with a somewhat more moderate geometry. As a Pro Series representative our REACTION is a thoroughbred race bike. It is equally suited for race use in XC races or marathons and for longdistance touring applications. For 2010 the difficult choice is between the GTC Carbon or HPA Aluminium: The frame in both the GTC carbon version and similarly in the HPA Aluminium version is distinguished by an RFR geometry designed to meet the needs of the XC racer. On twisty trails it is a very agile and strong sprinter but remains reliably on track on steep inclines and controllable at all times.
Both frames have the same successful geometry with a short wheelbase. The bike is therefore more compact and rides more agilely. In addition there is the option at all times to get the feet on the ground when stopping in demanding terrain. High-performance sprung forks with 100 mm of suspension travel are used. These provide safety on demanding courses. To reinforce the bottom bracket we use press-fit inner bearings on both frames. The wider housing width makes it possible to connect the bottom bracket and the chain stays more widely. As the housing width is a factor in the rigidity calculation every millimetre of additional width results in significant improvements in respect of lateral rigidity and the comfort-giving vertical flexing of the chain stays remains fully maintained as a consequence. Even greater rigidity and therefore improved acceleration values are the result.
