Rotor eKAPIC Crank Arms - eMTB | ISIS - for Brose Mag (QF 170 mm)

Rotor eKAPIC Crank Arms - eMTB | ISIS - for Brose Mag (QF 170 mm)

With the eKAPIC crank arms, mountain bikers come a significant step closer to the dream of a lighter E-Bike. To achieve a design specifically adapted to E-MTBs, Rotor has specifically developed the design and technologies of its proven MTB cranksets.

Trinity Drilling System. Thanks to three holes along the longitudinal axis of each arm, excess material is removed. Thus, the TDS process reduces to a significant extent the weight of the crank arms made of forged and CNC-machined aluminum, without negatively affecting the stiffness.

Narrow Q-factor. When it comes to tackling climbs, the eMTB clearly plays to its strengths, but is usually at a disadvantage in terms of pedaling feel compared to conventional bikes. With the realization of a Q-Factor that is as narrow as possible for E-Bikes, Rotor has not only addressed this circumstance, but also actively contributes to preventing biomechanical damage when riding off-road as well as problems with hips and knees.
