The next upgrade.

You wouldn't choose anything over your Race Face Next SL crankset, but you'd really like to add power data and dial in your training plan. Enter the Stages Cycling Carbon Single Leg Power Meter Crank Arm for Race Face Next SL. Pairing single-leg power measurement with efficient power transfer, this left crank arm transforms your crankset into a vital training tool with accurate power measurement no matter where the ride takes you.

Stages manufactures this crank arm, so it isn't exactly the same arm as your current Race Face one, but the only obvious differences are the Stages branding and the small power meter pod affixed to the arm's inner surface, adding the ability to gather pinpoint power data to better measure your ride. It utilizes a blend of strain gauges and an accelerometer to gather position and force data 64 times per second and deliver power readings with a claimed +/-2% accuracy that's right in line with what we'd expect from any quality power meter.

The gram counters among us will also appreciate that the Stages power meter adds a paltry 20 grams to the crank arm, which is a tiny sacrifice to gain the data tracking and training specificity having a power meter affords.

Great Little Weight Power Meter

  • Familiarity: I've put it through the wringer

Stages power meters are pretty sweet. They only measure the left leg, but are pretty accurate compared to some dual sided power meters out there.

I have been using their stuff for 2 years now, and have had little issues. I ride in all kinds of nasty weather, and everything is working fine. It is easy to switch between bikes. It only ads 20g to your existing crankset, so little to no extra weight at all.

Riding with power is one of the best ways to get stronger. It is the most consistent form of measurement for any output, unlike training or riding with heart rate.
