Rotor R-Raptor Crank Arms
$69.99
Rotor R-Raptor Crank Arms Info
The Rotor R-Raptor Crank Arms were designed around a straightforward idea: one set of arms that can adapt to multiple bikes, bottom bracket standards, and chainring setups rather than locking you into a single configuration. The arms are CNC-machined from 6082-series aluminum — the same material Rotor uses throughout their component lineup — for a stiffness-to-weight ratio that a traditional crank-and-spider arrangement struggles to match.
These arms are the foundation of the Rotor modular crank system. They attach to a 30mm spindle — compatible with nearly any bottom bracket standard that accepts a 30mm axle, including English-threaded shells of varying widths — and are designed for 1x drivetrains only, with support for both round and Q-ring chainrings. Crankarm fixing bolts are included. To complete the build, you'll need a compatible Rotor axle, your chosen chainring, and optionally crankarm bumpers — all available separately.
