Easton and Race Face both offer a very similar power meter called the CINCH Power Meter Spindle. The CINCH is a spindle-based power meter that replaces the OEM spindle. Easton’s version is compatible with Easton’s EC90 SL road cranksets and is a 129 mm long spindle. Race Face’s version fits Next SL MTB cranksets and is 136 mm in length. Easton and Race Face power meters are $599 and it allows users of these cranksets to easily and affordably add power to their bikes.
Assuming you have a compatible Easton or Race Face crankset, installation of the CINCH is quite simple. You just need to replace your current spindle, which attaches to the left side crank arm, with the CINCH. Therefore, installation typically takes no more than 15-20 minutes and can be done at home.
Easton and Race Face power meters weigh approximately 65 grams (weight of the spindle). This is likely just 20-30 grams more than the stock spindle you would be replacing – so added weight is relatively minimal.
These power meters operate as left side power meters. That is, they measure the force that is generated from the left leg. They double the value to calculate total power. This is how all left-side power meters work.
The Easton and Race Face Power Meters are a very convenient option if you have one of the compatible cranksets as you just need to swap out your current spindle. There is no need to change out any other parts of your drivetrain like you have to do with other power meters.
In addition, since the power meter is safely located in your bottom bracket, it is 100% protected from impact as well as rocks, rain and mud.
These power meters use rechargeable lithium-ion batteries. Battery life is around 400 hours. We note this is longer than most other rechargeable power meters.
The power meters transmit data via both the ANT+ and Bluetooth SMART wireless protocols. This means you can use them with any bicycle computer, smart phone or tablet. You can also use them with indoor training apps such as Zwift, TrainerRoad, etc.
Easton and Race Face power meters are accurate to within +/- 2.0%. This compares to +/- 1.0-2.0% accuracy for most other direct force power meters.
The CINCH measures cadence with a built-in accelerometer. Therefore, there is no need to use any magnets with this power meter.
Easton and Race Face power meters come with a one-year warranty which covers the product from defects in material and workmanship.
