Rotor R-Hawk Crank Arms
Rotor R-Hawk Crank Arms Info
The Rotor R-Hawk Crank Arms are built around a simple premise: remove every gram that isn't doing structural work. Rotor achieves this through Trinity drilling — three full-length longitudinal bores running through each arm — a technique that strips weight without compromising the stiffness that MTB riding demands. The result is a CNC-machined 7055 aluminum arm that comes in at 665g for the complete setup (175mm arms, standard thru-axle, and 30T Q-Ring).
These are arms only — to complete the crankset you'll need a Rotor axle (available in standard and Boost spacing), a chainring (1x only, with round and Q-Ring options), and crankarm bumpers if your setup calls for them. The 30mm spindle interface is broadly compatible with most bottom bracket standards built around a 30mm spindle, including English-threaded shells of varying widths. Crankarm fixing bolts are included.
