It’s Sea Otter time which means lots of shiny new bike announcements over the next few days. First up is Race Face and Easton — the two brands teamed up to launch a spindle-based power meter. Called the Cinch, it’s compatible with cranks from both companies.
The Cinch spindle-based power meter works with all East road, cyclocross, or gravel cranks and Race Face mountain bike cranks in both 1x and 2x configurations. A unique crank/spindle interface allows you to quickly remove the crank when needed and even swap the power meter between bikes (if the spindle length is right for each drivetrain — i.e., probably easier to swap between your road and gravel bike than your road and mountain bike).
The Cinch adds just 65 grams to your setup and delivers a battery life of around 400 hours — the internal battery is USB rechargeable.
The power meter supposedly delivers an accuracy of plus-or-minus 2 percent and measures both left and right side power. The corresponding Cinch Power Meter app shows battery level, performs calibration, and shows data including power, cadence, and pedaling efficiency. The power meter transmits in both Bluetooth and ANT+, so works with most bike computers and watches.
The Cinch power meter spindle is available in two lengths: 129mm for road/cross/gravel applications and 134mm for mountain bikes. The spindle-based power meter will retail for $599.99 without cranks included — closer to $1000 if you need a crankset to go with it.
