Rotor eKAPIC BROSE® QF170 CRANK ARMS 170 mm
170 mmProduct details
The eKAPIC cranksets are forged from 6082 aluminum and CNC-machined. They are manufactured with our proprietary Trinity Drilling System for the perfect balance of weight and stiffness, specifically optimized for the demands of e-biking. These specialized eMTB cranksets leverage the benefits of ROTOR's decades of research, technology, engineering, and design from its existing mountain bike crank series.
Narrow Q-Factor
The new eKAPIC cranksets are designed to have a narrow Q-factor to improve ergonomics while pedaling. This Brose-compatible version has a Q-factor of either 170 or 184 millimeters. Be sure to choose the right version for your bike. The pedaling position feels very similar to that of a non-motorized bike and is based on decades of research into bike fit and biomechanics.
Universal Tooth Design
In the race for proprietary designs that promote the strength or efficiency of one system over another, a often overlooked pivot point is the chainring. It must be compatible with the entire drivetrain, from the cranksets to the cassette and back to the chain. Our development team has finally found the solution and developed a universal tooth profile that allows compatibility with any 1x e-MTB group on the market.
The ROTOR Universal Tooth Design is compatible with SRAM®, Shimano®, and KMC® MTB chains.
