SRM FSA K-Force Light Compact Wireless PowerMeter Info

The SRM FSA K-Force Light Compact Wireless PowerMeter pairs SRM's eight-strain-gauge measurement system with FSA K-Force Light cranks — a combination that delivers ±2% accuracy in a package built for riders who train and race with data they can trust. Power and cadence transmit wirelessly via ANT+, making it compatible with the wide range of ANT+ head units already used by serious riders.

The compact chainring configuration — 50/34 with a 130mm large BCD and 110mm small BCD — suits riders who want versatility across varied terrain without sacrificing the crankset's stiffness-to-weight character. The included FSA MegaEXO ceramic bottom bracket comes in at 92g, and the full powermeter assembly weighs 806g excluding the bottom bracket. Battery life is rated at 1,400 hours, so it will outlast a full season of heavy training without a concern. Available in 170mm and 175mm crank arm lengths. Head unit sold separately — any ANT+ compatible computer will display power output from this unit.
