Carbon Road GXP L Gen 3 Power Meter Crank Arm
So you've got a perfectly good SRAM GXP road carbon crankset and you've been dabbling with the idea of upping your game and training with power. Stages has the solution to keep your drive-side arm and rings and add single-leg power in an affordable way to get the most out of your rides with its Carbon Road GXP L Gen 3 Power Meter Crank Arm. This made in-house carbon arm is extensively tested for accuracy and provides a cost-effective option for adding power to your existing SRAM GXP carbon crankset.
This isn't exactly the same crankarm as your current SRAM one, but the overall shape and carbon weave is very similar to the SRAM arm and of course, there's the Stages branding. On the inside of the arm is a power meter pod that’s bonded to the surface adding the ability to measure wattage so you can accurately gauge your efforts and train more effectively. Inside the IPX7 water-resistant pod are strain gauges and a Gen 3 updated accelerometer that measures rotational speed and the slight torsional bending of the arm 64 times per second to calculate power readings with a claimed +/- 1.5% accuracy that's perfectly in line with what we'd expect from any quality power meter. Stages uses Active Temperature Compensation that automatically adjusts for temperature swings during the ride so the measurements are more consistent. And to ensure your computer doesn't miss a watt, the Bluetooth LE and ANT+ radios have been beefed up to offer data transmission strength that’s 6 times stronger than before and the wireless firmware downloads via the Stages App lets you easily keep the power meter up to date.
Stages pulls off this amazing feat placing everything in a package that only adds 15 grams to the crank arm, which is next to nothing compared to the massive data tracking and training specificity that having a power meter affords. That's about the same as a swig out of your water bottle for a device that can certainly get you fitter than ever before.

What do you think about this product?

- I've used it several times
I have used the Garmin Vector pedals for the last couple of years but they recently broke and I decided to give Stages a try. This power meter feels simpler and thus I expect them to be more durable than the Vectors. I also like the fact that they are bluetooth and ANT+ capable to communicate with my head unit or phone. Reliable so far.
