Precision for Speed & Efficiency. Balanced for Versatility. Engineered to be the last crank you'll ever need. Whether you're racing roads, grinding gravel or chasing watts on every climb, StW arms are CNC-machined from billet aerospace-grade Ti-6Al-4V — an alloy widely used in aviation and motorsports — and built around three obsessions: compatibility, ergonomics, and performance that punch far above its featherweight. The titanium arms transmit your power more directly, preserves your energy more efficiently and keeps your pedal stroke stable longer in your ride. The reduced frontal surface area means you may pick up speed from the same watts. StW's ride like a 700 gram crankset because it doesn't know it lost 400 grams from the arms. Our proprietary AxLoQ clamping system has 5mm of axle width adjustment, so DUB Road and DUB Road Wide compatibility live in the same crankset. A switch requires only a cassette tool and a hex key. No pre-load rings, no compromises.
