Rotor Rex1 Now available


This aero spider version of the 3D+ reduces aerodynamic resistance without gaining the extra weight of a full-aero crank arm. It offers 30 mm axle performance for your bike – regardless of which BB system it has.

The new Micro Adjust Spider (MAS), offers more positions to suit every rider’s needs. Our new advanced MAS spider has an alternative bolt hole placement allowing for intermediate positions between existing OCP (Optimum Chainring Position) of the Q-Ring.

A standard crank in combination with the OCP the Q-Rings, allows approximately 5 degrees of adjustment. The MAS spider when used with Q-Rings offers half positions giving approximately 2.5 degrees. This means that you can micro adjust the position of your Q-Rings, to suit your riding style.

The MAS is available as an option in 3D+ range in road 130 & 110 BCD cranks, the POWER and FLOW cranksets only use MAS spiders.
