Easton Cinch power meter
aston’s new Cinch power meter is single-sided and costs £770. At first glance, this doesn’t sound like much of a bargain, but the Cinch isn’t your standard system. Easton says its cost has to be balanced against its design: packing all the important stuff inside the spindle provides several practical advantages over spider or crank-based systems. Hidden inside the bottom bracket shell, the Cinch is protected from crash damage and water ingress. This also ensures there are no issues with crank arm clearance.
Most importantly, according to Easton, crank arm lengths can be changed if required, as can chainset configurations. This means you could use it on the road with a two-chainring set-up one day, then change it to 1x for a gravel ride the day after, as easily as you’d swap slick tyres for knobblies.
Its Usb-rechargeable battery has a claimed 400-hour life and the meter keeps up with the competition with a +/- 2% accuracy.
Easton makes cranksets, spiders and chainrings that are compatible with the spindle, so putting together a power meter for any occasion should be, well… a cinch.
