The SRAM S975 SRM Power Meter GXP Crankset puts SRM's measurement hardware inside a road crankset built to GXP interface standards — giving you accurate, wireless power data without the bulk of an aftermarket add-on. Eight strain gauges work together to deliver power readings to ±2% accuracy, which puts this unit in the range serious training and racing demands.

Data transfers wirelessly via ANT+ only, so any ANT+-compatible head unit will read power and cadence directly. Battery life is rated at 1,400 hours — long enough that mid-season battery anxiety isn't a real concern. The crankset ships with chainrings and cranks included; a bottom bracket is sold separately. No head unit is included — pair it with the ANT+ computer of your choice.
