Description
About the SRM ROTOR Track Power Meter
The SRM ROTOR Track Power Meter takes SRM’s gold standard of power measurement to the track. The power meter can measure up to 4,000 watts, as well as the smallest changes in pedal stroke – all while maintaining +/- 1% accuracy. The SRM ROTOR Track Power Meter comes with ROTOR’s 3D crank arms and a 24 mm bottom bracket spindle. The ROTOR 3D crank arms use the Trinity Drilling Process to create a crank arm that is both light and very strong. The power meter provides 1,900 hours of battery life and comes in a 144 BCD.
Options
- Crank Lengths: 165 mm | 167.5 mm | 170 mm | 172.5 mm | 175 mm | No Crank Arms – Spider Only
- SRM PC8 Cycling Computer Bundle. You get $249 off the standard price of the PC8 when you buy it with a SRM power meter

Compatibility
The power meter comes with a 24 mm spindle and allows for direct integration into threaded BSA framesets. All ROTOR track cranks require the ROTOR Track Threaded Bottom Bracket for proper installation. The ROTOR Track BB offers quality steel bearings inside ultra stiff, machined steel cups.
