Easton CINCH Power Meter Crankset

The Easton CINCH Power Meter Crankset brings power to your road, gravel or CX bike. Safely protected within your frame’s bottom bracket, the Easton CINCH spindle provides accurate and reliable power and cadence data. Like other, popular left-side power meters, it measures left leg power and doubles it to calculate total power. However the CINCH is hidden in your frame. This means you don’t have to worry about clearance issues with your chain stay – a common concern with other left-side, crank arm-based power meters.

The Easton power meter uses a rechargeable lithium-ion battery which provides 400 hours of battery life and adds a mere 65 grams to your bike. The CINCH is both ANT+ and Bluetooth compatible, so you can use your favorite head unit or smart phone.

In addition, Easton’s best in class EC90 SL crankset is light, stiff and highly adaptable. The EC90 SL allows for both direct mount 1x rings as well as direct mount 2x spiders. The EC90 SL has a standard 149 mm Q Factor and will fit every major road bottom bracket standard. You can purchase the complete EC90 SL crankset with the CINCH power meter for $949. The result is a power-equipped, light, stiff, industry leading crankset!



The CINCH Power Meter is compatible with the Easton EC90 SL and EA90 cranksets only.
