Simplicity's not a word that we'd typically associate with a power meter, and we definitely never thought we'd use it to describe anything Super Record. But—counting the top line—we've already used it twice to introduce the Stages Cycling Campagnolo Super Record Single Leg Power Meter Crank Arm. The unit's also modular, as swapping it between bikes only requires that you swap the crankset over or just the left crank arm. The result is reliable power measurement incorporating two different technologies—Stages power measuring and the three C's (Campy, carbon, and ceramic) of Italian cycling—that have won all three of the most recent Tours.

Carbon and ceramic bearings aside for now, rest assured that the crank arm the meter's attached to is the same harpoon that Il Squallo used to skewer the competition in 2014. The real story here is with the meter itself, though, and the technology housed within that innocuous little cartridge is responsible for the numbers that Froome and company ride tempo to.

Tucked inside that little pod, strain gauges and an accelerometer measure force and rotations to deliver power data to your head unit with a claimed accuracy of +/-2%, which is in-line with other quality power meters on the market. It also incorporates Stage's Active Temperature Compensation (ATC), which compensates for the natural expansion and contraction of the strain gauges by adjusting the readings depending on external temperature. ATC accounts for those temperature changes without requiring you to stop pedaling in order to zero the system. Overall, the power meter adds less than 20g to the crank, which is a tiny tradeoff for the ability to chart limits, plan training regimes, and monitor efforts on race day.

  • Italian racing luxury meets innovative power measuring
  • Measures power with an industry-standard +/-2% accuracy
  • Active Temperature Compensation accommodates changing conditions
  • Internal accelerometer covers cadence with no additional sensors
  • Wireless communication keeps use and maintenance simple
  • Pairs with Stages Power App for firmware updates and zero resets
  • 200+ hour battery life with easily-changeable CR2032 battery
  • Stages Cycling brings power data into an affordable price range

Excellent choice for a powermeter

  • Familiarity: I've used it several times

I pondered the myriad of choices for a powermeter and decided that replacing my Campagnolo Super Record left crankarm was the best cost-effective and simple option for me. I bought the Stages Power meter and initially found that it wasn't pairing with my Garmin Edge 1030. A quick call to Stages tech service, and "duh", I merely needed to select "discover new powermeter" on the Garmin (I had assumed that the Garmin would pick up the signal automatically.) Since then, it's worked perfectly in the 2 months I've had it. Time will tell regarding it's durability, but I'm impressed thus far.

Don't Change Out Your Sweet Campy Crank

  • Familiarity: I've put it through the wringer

Don't change out your sweet Campy crank that you have on your bike. Stage's has an easy solution for you. 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.

For compatibility on frame, take a 10mm allen key, and try to stick it between your non-drive side crank arm and chainstay. If it can run up and down the crank arm and fits between the two, then your frame will have enough clearance for the power meter.
