Sram SRM Professional power meters utilize SRM's proven technology, which uses eight strain gauges to measure power output within +/- 2% accuracy. This enables cyclists to scientifically manage the specifics of their personal program, avoid overtraining, and assess and interpret reactions to a variety of training and racing stimuli.
The Sram SRM Professional measures power, cadence, temperature, heart rate, energy consumption, speed, ride time, ride distance, unlimited intervals, and times in any training zone.
