Rotor Bike Components Rotor Kapic Carbon Crank Arm

Before ordering, ask for availability.

Thank you.

Kapic Carbon is our lightest and stiffest crankset ever at 429g (175mm, 32t w/o BB) and was developed in response to the modern MTB rider’s cutting-edge bike design to withstand the most demanding riding conditions, with an incredible result in weight, strength and rigidity.

Thanks to the practical modular design, the crank arms can be adjusted to almost any frame standard and your personal preferences by using different axles and chainrings. BOOST or non-BOOST frame? Oval or round chainrings? Changing the chainrings quickly to adapt the translation to the terrain? No problem for the KAPIC crank!

Direct mount:

All current ROTOR cranks from the ALDHU and VEGAST road series, the RHAWK, RRAPTOR and KAPIC MTB series and the INpower DM and 2INpower DM power meters use the Direct Mount system, which has been established in the mountain bike sector for years, to mount the chainrings. This enables easy chainring changes, direct traction on the axle and maximum flexibility when choosing the gear ratios and drive characteristics. In addition, the fine gearing between the crank and the chainring enables oval ROTOR Q-Rings chainrings to be adjusted to an accuracy of 1°
