The XCADEY XPOWER-S GEN2 Shimano MTB Power Meter is compatible with Shimano direct mount MTB cranksets. It measures power from both legs, is accurate to +/- 1.0% and is lightweight at only 100 grams. Because this power meter can be added to your existing crankset, there is no need to buy new cranks or replace your bottom bracket.
The power meter features a rechargeable battery with 150 hours of ride time, left and right leg power balance, active temperature compensation and a 2-year manufacturer’s warranty. Bluetooth SMART allows you to use it with your favorite indoor training program or app.
Key Product Details
Compatibility:
This XCADEY is compatible with Shimano MTB direct mount cranksets using a 1x chainring. It uses a 104×4 bolt pattern and works with bikes that use Boost spacing. These bikes usually feature a 52 mm chainline and 148 mm rear hubs. See Compatibility tab for more information.
Power Measurement:
The XCADEY power meter measures power at the spider and is therefore able to measure power from both legs.
Key Features:
Dual-leg power measurement, accurate to +/- 1.0%, 150 hours of battery life, rechargeable battery, very lightweight, left/right power balance, ANT+ and Bluetooth compatibility, active temperature compensation.
Advice From Our Staff:
The XCADEY is a great way to add power to Shimano MTB direct mount cranksets. It is an affordable and lightweight option which makes it a great option for cyclists looking to minimize added weight.
Compatibility
Crankset: The XCADEY Shimano MTB Power Meter is compatible with Shimano MTB direct mount cranksets such as the M9100 series, MT900-1, M8100 series, M7100 series, M6100 series, MT611-1 and MT610.
Chainrings: This power meter requires a 104 BCD 4-bolt MTB chainring. If you don't already have a compatible chainring, we have several to choose from.
- MTB chainrings
- MTB chainrings for Shimano (for Shimano 12-speed drivetrains)
Please note this power meter is NOT compatible with SRAM X-SYNC 2 Chainrings. The tabs on the X-SYNC 2 are a bit larger than on some other chainrings and they don't fit with the shape of this power meter spider.
The smallest 104x4 chainring you can use on a XCADEY MTB power meter is a 30T round or 32T oval.

Short term review, product loose well made and almost factory once installed. Simple to operate and install and have had no pairing issues with my wahoo elmnt roam v2. Operations is seamless with a simple one click on the head unit to calibrate.
Battery seems to last forever have had 6 rides so far and not even put a dint in the storage.
Seems to be reasonably accurate +- 5 w when compared to my indoor trainer.
Would purchase again.
Devon Vigus (verified owner) –
Ive had many power meters, (SRM, Power Tap, Stages, Quark) but I didn’t want to spend a ton of money so I decided to give XCADEY a try. I am impressed with the design, low weight, rechargeable battery, and fair price. It pairs easily to my Garmin 840 and seems to read accurately. I have been a professional cyclist in the past and now i am a cycling coach so I am very familiar with power numbers. I bought this for my trail bike and I am happy I did. Powermeter city has a great selection and shipping was fast. Stoked!
Power Meter City –
Hi Devon! Thanks for the awesome feedback! It means a lot coming from someone with your experience. Glad the XCADEY is delivering great performance for your trail bike and that our selection and shipping met your expectations. Keep enjoying the rides and coaching! Ride safe!
