Rotor
Flow noQ Aero Ring Crank 53/39
Designed using CFD (computational fluid dynamics) to maximize benefits, the paradigm-changing Rotor FLOW aero crank was made for both aero road bikes and pure TT bikes. It offers the time savings of classic aero cranks and the performance of leading road cranks, all at once.

ROTOR?s CNC-machined cranks feature our Trinity Drilling System, which is a process that drills three full-depth holes along the axis of the crank. This allows us to remove excess material from the crank arm resulting in a lighter crank without compromising its exceptional stiffness-to-weight ratio.
AERO
ROTOR Aero components, such as Aero chainrings or the flagship aero FLOW crank, help cyclists maximize their wattage output in the war against wind resistance. Tapered FLOW crank arms optimize aero behavior, while a smooth, solid aero chainring surface reduces aerodynamic drag.
MAS
?MAS? stands for Micro Adjust Spider and means ?more? in Spanish. That?s what this technology is all about: more adjustability to further optimize your Q rings. Additional bolt holes allow for intermediate positions between a Q ring?s existing Optimum Chainring Positions (OCP). A standard crank and Q-Ring combination offers approximately 5 degrees of OCP adjustment. MAS together with Q rings offer half positions of approximately 2.5 degrees of OCP adjustment. This means you can micro adjust the orientation of your Q rings to fine-tune your pedal performance.
