June 8th, 2015 – The Ambassador of Power Meters
Shimano vs. SRAM. Stakeout your position and defend it with every watt you can muster. Now Shimano riders can finally take advantage of SRAM’s Quarq power meters to measure their watts with the Elsa RS, designed for Shimano’s four-arm Hollowglide chain rings. Quarq has packed the Elsa RS with its next-level measurement tech—accelerometer-based cadence, Power Balance, active temperature compensation, IPX7 waterproof rating, Omniçal and its standard setting with some 1.5-percent accuracy.
