The SRM Track PowerMeter was designed to be the pinnacle of precise power measurement in the sport of track cycling. Track cycling has always been a focus for SRM, due to the detailed nature of specific training intervals as well as the close timing of competition to the thousandth of a second.

The SRM Science Track PowerMeter version is available for both the square-tapered and Octa-link bottom brackets with a dual 144 BCD, for threaded or two piece chain ring screws.
