ROTOR KAPIC Carbon crank arms for XC and Marathon mountain bikes. The lightweight KAPIC Carbon crank system was developed from the KAPIC aluminium and shares the innovative and modular design with it. The KAPIC Carbon is currently the lightest (429g) and stiffest crank system in Boost and Super boost design for mountain bikes from ROTOR and thanks to Direct Mount technology offers the best possible direct conversion of power into propulsion.
Without special tools the assembly is done in minutes and changing the chainring is just as easy. Thanks to the Direct Mount system, where the blades are mounted directly on the shaft without a spider, a standard Allen key is sufficient as a tool. Numerous blades in round design or with the oval Q rings from ROTOR offer a choice for the ride in any terrain.
The Direct Mount System of the ROTOR KAPIC Carbon allows the fine adjustment of oval chainrings (OCP) in one-degree steps and thus an incomparable individualization to the personal demands. This gives the driver the best possible approach to optimum step efficiency. The crank arms of the KAPIC Carbon offer an ideal ratio of stiffness to weight.
ROTOR KAPIC Carbon is perfectly suited for XC and marathon bikers who want a light crank system without complications, with low maintenance and installation costs and the possibility of improving step efficiency. Protective covers in seven different colours allow the colour to be matched to the frame and offer further individualisation.
The KAPIC Carbon is of course compatible with other mountain bike groups from Shimano or SRAM and offers a future-proof technology thanks to Direct Mount.
