The VBC (Variable Bolt Circle) crank set is both an elegant and durable addition to your road or track bike. This crankset is designed to be used as a double with VBC chainring setup, however, it can also be paired with any White Industries splined chainrings where a low Q-factor (150mm w/ 113x68mm BB) is desired. A narrow Q-factor allows the arms to sit close to the chain stays effectively giving one more direct power transfer into each pedal stroke<br /> <br /> Crankarm sets include White Industries self-extracting crank bolts and lockring. They are available in polished silver or hard anodized black. Lengths: 165mm, 170mm, 172.5mm, 175mm and 180mm<br /> <br /> Chainrings and chainring bolts sold separately.<br /> <br /> Made in the U.S.A.
