Product Description

The eKAPIC cranks are forged and CNC'ed from 6082 aluminum and crafted using our proprietary Trinity Drilling System for the perfect weight to stiffness ratio, specifically optimized for the demands of e-biking. These dedicated eMTB cranks take advantage of our decades of research, technology, engineering, and design from ROTOR’s existing range of mountain bike cranks

Narrow Q-factor

The new eKAPIC cranksets are designed to keep a narrow Q-factor to improve pedaling ergonomics. This Bosch-compatible version has a Q-factor of 171 millimeters. The pedaling position closely mimics the feel of pedaling a non-motorized bike, taking advantage of decades of research into bike fit and biomechanics. 

Universal Tooth Design

In the arms race for proprietary designs encouraging strength or efficiency of any one system or another, an often-overlooked lynchpin is the chainring. It must be compatible with the entire drivetrain, from cranks to cassette to chain and back around again. Our engineering team has finally found the solution and engineered a universal tooth profile to unlock compatibility with every 1x e-MTB groupset on the market. 

ROTOR’s Universal Tooth design is compatible with SRAM®, Shimano® and KMC® MTB chains.
