Stages Carbon GXP for SRAM Road Power Meter
The Stages Carbon GXP for SRAM Road Power Meter is a proprietary Stages carbon crank arm, made specifically to work with SRAM GXP road cranks. Like all Stages power meters, this unit features +/- 1.5% accuracy, 200 hours of battery life and is lightweight at only 15 grams of added weight. In addition, the power meter is compatible with both ANT+ and Bluetooth SMART devices. This means you can use a bicycle computer with ANT+ or your smartphone or tablet with Bluetooth SMART.
The new Stages Generation 3 power meter features radio antennas that are 6x more powerful than the previous version. This means better compatibility with both bike computers and watches. The new versions also feature improved accuracy and have an LED indicator light on the housing for improved ease of use.
Key Product Details

Advice From Our Staff:
Stages left side crank arms are some of our best-selling units. They are affordable and easy to install. The one consideration is they only measure left leg power compared to some other power meters that measure power from both legs (those versions usually cost more however).
Options For This Power Meter
Crank arm lengths: This power meter is available in the following crank arm lengths:
- 165 mm | 170 mm | 172.5 mm | 175 mm
Compatibility
Crankset: This Stages power meter is made specifically to work with most SRAM GXP road cranks.
Check Frame Clearance: Crank-arm based power meters like this one attach a sensor on the inside of the left crank arm. On some bikes, there is not enough room between the left crank arm and the chainstay for the sensor to clear the frame. Therefore, you should make sure you have at least 10 mm of clearance between the left crank arm and the chainstay - and that you don't have a bottom bracket mounted rear brake (used on some aero and TT bikes). The important area to measure is right in the middle of the crank arm. Please refer to the image below.
If you find that you have around 7-9 mm of clearance, what many people will do is simply install a 1 or 2 mm bottom bracket spacer (between the left crank arm and the frame), which will give them the clearance they need.

I purchased my power meter in February and just got it installed last week. I highly recommend Stages and Power Meter City. Website was easy to use, order updates were frequent and it was delivered in less than a week. I have 4 rides completed with the Stages Power Crank and I love it! Will be buying another one for my Mountain Bike shortly.
