Detailed product description

MAS: Micro Adjust Spider
MAS is more (not only translated from Spanish). MAS is an abbreviation for Micro Adjust Spider. This technology allows you to adjust your Q-ring very accurately. There is a second position for the Q-ring.

The INpower power meter are linked with the oval chainrings by Rotor. The introduction of TORQUE 360 and Optimum Chainring Angle allows you to make an exact analysis of your pedal stroke. You can use this data to place the Q-rings in a perfect position and use these oval chainrings optimally.

An important technology that is used for Rotor cranks is the so-called Trinity Drilled System. The crankarms are hollowed thrice in length which saves a lot of weight. These crank arms can resist rotation and bending force better than standard cranks.

Suitable for:
• BBright
• BB386 EVO
• BB30 (68 or 73)
• PF30
• BB86
• ITA (70)
• BSA (68 or 73)
