Given the prevalence of the Record name in the heritage of cycling, Italy, and Italian cycling, you'd be forgiven for assuming that "Record" was Italian for cycling. It's not. Well, not literally. But it's centrality to cycling's halcyon past does mean that it may as well be. With the Campagnolo Record Single Leg Power Meter Crank Arm, Stages Cycling ushers this icon of cycling heritage into the contemporary realm of power meters, data mining, and smart training.
That's not to say that the Record crank arm is itself old-fashioned. Its hollow carbon crank arm and USB ceramic bearings define the top-end of racing kit. The only possible top-endier option being the appropriately named Super Record, which incorporates even smoother CULT ceramic bearings. Italian engineering aside, the real star here is the little pod clinging to the inside of the crank arm.
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.

No Need For A New 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.
What does Stages do with all the right-side crank arms? Or does Campagnolo sell them lots of left-side only cranks? Just wondering!
Stages buys just the Left arm from companies to make the conversion. they also do sell full cranksets upon request.
