All CINCHed up

Ever lined up at the start line knowing this race is in the bag, only to find out you are desperately under geared? With the EC90 SL CINCH Power Meter Crankset not only do you get industry-leading versatility, making on-the-fly 1x or 2x drive spider changes easy, you also get spindle-based power measurement delivering precise, reliable data to your smartphone or ANT+ head unit.

Designed around the EC90 SL Crankset, Easton did away with the standard crank spider and ensuing spider-mounted chainrings of old. Utilizing Race Face's Cinch technology, this crankset uses Direct Mount 1x or 2x spiders, dropping grams and eeking out every last watt that you generate. This revolutionary new design makes fine-tuning your 1x setup to suit the course after a pre-ride, or converting your 'cross bike to a winter road bike at the end of the season as easy as a few turns of a wrench.

While the lightweight and versatile crankset is revolutionary in its own right, the real game changer is the CINCH spindle-based power meter. Housed inside the 38mm alloy spindle, the highly adaptable CINCH system boasts a 400+ hour battery life while only adding on 65g to the crankset's weight. With dual Bluetooth transmission and an ANT+ radio to connect to your head unit of choice or smartphone, see your power, cadence and pedalling efficiency data in real time. With the CINCH Smartphone app, check your battery levels, install updates, and calibrate your power meter all on the fly.

Includes Easton CINCH Power Meter Spindle and EC90 SL Crank arms, CINCH Power NDS Crank Bolt Adapter, 8-16mm Hex Adapter, CINCH Crank Extractor, Antenna Cap Tool, Micro USB Cable. Direct Mount rings and bottom bracket not included.
