Carbon 30mm/386EVO L Gen 3 Power Meter Crank Arm
It's hard to argue the benefits of training with a power meter if you're looking to get fit. Having quantifiable data from a response while on the bike is so much more specific than perceived exertion and heart rate and the geniuses at Stages now makes it easy to add a 30mm spindle carbon crankarm to your existing crankset, without a hefty investment, so you can start training like a pro. With five separate spindles, you can retrofit the Carbon 30mm/386EVO L Gen 3 Power Meter Crank Arm to work with your FSA 386, SRAM BB30, and Race Face Next SL cranks with ease providing you with valuable data in a lightweight package.
This non-drive side carbon arm's profile and finish closely matches the offerings from the other brands with the exception of the Stages branding and the small power meter pod affixed to the arm's inner surface, providing the power data to help you measure your ride and efforts. It utilizes strain gauges and an accelerometer to gather position and force data 64 times per second and delivers power data and cadence with a claimed +/- 1.5% accuracy that's right in line with other high-quality power meters on the market. Additionally, the system constantly compensates for temperature changes for increased accuracy, the firmware is wirelessly upgradable, and the updated BlueTooth and ANT+ radios offer an improvement of transmission strength by 6-fold.
Finally, the Stages power meter adds around 15-grams to the bare crank arm, which is nothing considering the data tracking and training specificity that having a power meter affords. The unit's water resistance rating stands at IPX7 and the user replaceable CR2032 battery lasts for approximately 200 hours.

Own 3, going on 4 (4 different bikes)
- Familiarity:
- I've put it through the wringer
Once I started power training, and riding >2hrs, it became more apparent to me to target power zones over HR or speed. Perceived exertion is the best, but after 5 days in the saddle, the power reports don't lie. I don't have enough money to buy 4 quarq meters, so... stages is far more economical. I started with my gravel rig, then my wife's, then my XC mnt bike... now one for my wife's XC mnt bike. Of the 3 we own, my wife's gravel bike meter measures 10-15% above her indoor trainer (perceived), but it's consistent. We have only SRAM cranks. Easy to install. Make sure you get the correct spindle. I required an additional spacer on my XC bike to get the right spacing for my 1x12 DUB Eagle XO1 crank set that I needed my LBS to sort out, but now that it's on, no issues. Paired well with my previous Garmin 500, and now Wahoo Bolt without any issues. As for the crazy numbers in the previous post... mine did the same, and I had to re-calibrate 3 times, meter in the 6 o'clock position only on my mnt bike. Now it's consistent with my indoor trainer, my gravel bike, and has been rock solid. I was getting computer drop outs with my Garmin 500, but not an issue with the Wahoo bolt
