SAINT PIRAN - Rotor Chainset Power Meter With Rotor Chainrings

SAINT PIRAN - Rotor Chainset Power Meter With Rotor Chainrings


Rotor 2inPower Road Chainset Power Meter With Rotor Chainrings

The Rotor 2inpower meter extends the technology of the original rotor inpower by doubling the strain gauges for true left / right leg balance and also adds bluetooth smart functionality as well as a built-in, usb-rechargeable li-ion battery.

The design provides power data for each leg independently, giving precise feedback on where improvements can be made to offer an advantage to those pushing the limits of performance. The four axle-based strain gauges of the original inpower remain, giving data from the left leg while four more have been added to the right crankarm itself.
