SRM Offers New AX-LIGHTNESS Peloton Road PowerMeter


SRM has added AX-LIGHTNESS to its growing list of power crank options, with the new PowerMeter AX-LIGHTENESS Peloton Road.

The new PowerMeter features a forged aluminum crank with a 30mm axle, that’s compatible with BSA, BB30, BB386, BB386 Evo and BBright bottom bracket standards.

However, the new PowerMeter is only available in a compact version with a 110 mm bcd, along with chainring options of 50/34 and 52/36, with crankarms available in lengths of 172,5 mm and 175mm.

According to SRM, the AX-LIGHTNESS Peloton Road has the accuracy of +/- 1%, with a battery life of approximately 1,400 hours.
