SRM FSA K-Force Light Wireless PowerMeter Info

The SRM FSA K-Force Light Wireless PowerMeter pairs SRM's proven power measurement hardware with FSA K-Force Light carbon cranks, giving you a complete, ready-to-ride crankset built around eight strain gauges and ±2% accuracy. Power and cadence data transmit wirelessly via ANT+ — no magnet, no wire, no interference with your drivetrain setup.

The unit ships with 53/39 chainrings on a 130 BCD, an FSA MegaEXO ceramic bottom bracket, and a total crankset weight of 806g excluding the bottom bracket. Battery life is rated at 1,400 hours, so this is not something you'll be charging between rides. Because it transmits over ANT+, it works with any ANT+-compatible head unit — the computer is sold separately.
