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.

Mixed feelings, good product that could use stiffer rings.

There are not very many reviews on this Easton Power Cinch double crank. I took a dive and decided to go for it. I have used the standard non power Cinch crank with an Easton 1x ring and it is a fabulous product. The rechargeable spindle mounted power meter seduced me the most. Having used another brand power meter for a good number of years on multiple bikes, the thought of not having to keep adding to my pile of coin cell lithium batteries was appealing, let alone dreaded dead batteries due to water infiltration and what have you. The advertised battery life is stellar, but what will the real world experience be like?
So here we go. Mechanically, the crank arms and spindle and as awesome as the standard, essentially the same. The spindle has a central cover assuming there is some sort of torque load cell there. Mounting was a breeze, charged up and connected via Bluetooth quickly to my iPad to update the firmware. The Easton account and login (required for updates) was a bit hard to figure out at first, but once in, it an issue. Calibrated quick and the meter seemed accurate and work well for a few months using ant. Then sometimes during rides, the meter would read zero for a few minutes. Maybe twice during a ride it would do this. It would say connected but would read zeros. If I forgot it and tried reconnecting, it would not pair, and tried Bluetooth with different rates of success. Then a bit later as the rains of autum set in, the battery started to drain quickly. It would go dead after a few days. Every time I charged it, it would do the same. It would work while it had juice left, it just would not last but a few days. Then some days it would read power level that seemed off. Something was definitely wrong. I recorded the battery history for a few weeks and contacted Easton and shared my data. They replaced it with a new spindle, and its been working great since. I have yet to run the battery dry, it lasted a few months before the original started going bad, and the new one is still going on a few months, but at the rates they have been wearing down, it seems like they will last a good long time. I purchased a second one, and has been working fine.
Now onto the chainrings. They shift great, just a touch slower than Shimano DA, but no issues there. I run the 52t up front, and I feel the big ring is too flimsy under high load. When sitting in the big ring and a small cog, if I jump on a max effort sprint, the chain would often slip off the front ring on the outboard side with a snap, as if the chain angle to the small cog in the back was forcing the chain off the ring, maybe combined with the ring deflecting outboard. I adjusted the front drailleur (Etap) so that it would gently rub on the outboard side, even then, t
