Rotor used CFD to redesign the crank arms to significantly reduce drag. Somehow, Rotor have still made it lighter and stiffer than other aero cranks to deliver all of your power. You will love the adjustability of the MAS spider to get your specific Q-Ring position.

Rotor Flow BB30 130BCD Aero Cranks (no rings)

The aero shape of the Rotor Flow BB30 130BCD Aero Cranks (no rings) crank arms is specifically designed from a purely functional perspective in performance and not just aesthetics using the Computer Fluid Dynamics (CFD) design. The CFD is a software program that can simulate an actual wind tunnel test at the same time enabling us to isolate a specific part of the bicycle in motion. The rigidity is not compromised, as it is 10% stiffer and lighter (563 g w/o chainrings – 175 mm) than most aero cranks on the market.

The aero profile of the crank arm has been optimised according to the varying airflow the crank encounters from the axle to the pedals, throughout the 360° pedal stroke. The crank arms and the spider are designed separately in order to acquire a maximum advantage of the crank’s aero profile. In terms of time saving, an athlete is 26.4 seconds faster when averaging 200 watts over a 180 km distance using these Rotor Flow BB30 130BCD Aero Cranks.

The Micro Adjust Spider (MAS) ensures perfect Q-Ring setup, offering adjustment increment gaps half that of classic spiders. Fantastically, these are compatible with BB30 or classic BSA threaded frame using ROTOR BSA30mm BB Cups.

3D BB30 Axle is compatible with

  • Cervelo BBRight specification
  • BB30 frames 68mm width
  • Classic threaded frames (using the NEW ROTOR BSA threaded 30mm bearing cups)

Chainrings are not included.
