Rotor R-Hawk Crank Arms
Like Rotor’s cross-country mountain bike-oriented REX cranks, the R-Hawk is machined for maximal strength and low weight. In addition to being light and rigid, the R-Hawk was designed to be modular so that it can be easily adapted to current and future spacing standards. It has a 30mm spindle size that is compatible with a variety of bottom brackets such as BBright, BB30, PF30 and BSA, but uses a separate axle which can be swapped out to accommodate bikes used for various disciplines.
The modular design also extends to chainrings, which are available separately. Featuring Rotor’s patented Optimum Chainring Position tech, the rings are easily swapped using just one tool: an 8mm Allen wrench. A preload adjuster on the non-driveside crank fastens the cranks in place.
Compared to R-Raptor, the 100 % CNC-machined R-Hawk is lighter due to its material and to more CNC machining during the manufacturing process. R-Hawk features Rotor’s signature Trinity Drilling System, which is a process that drills three full-depth holes along the axis of the crank. The 175 mm R-Hawk crankset weighs 665g with a standard axle and 30T Q-Ring.

Bill Lightweight and strong with no flexy feeling whatsoever. Very nice looking on the bike. Love the rubber boots to protect the paint from rock strikes and shoe rubbing. Took a little bit to get them to thread onto the axle, but once they were on, have been excellent.
