XCADEY XPOWER-S GEN2 E*Thirteen MTB Power Meter
The XCADEY XPOWER-S GEN2 E*Thirteen MTB Power Meter is compatible with E*Thirteen cranksets and Boost chainlines. This power meter is lightweight at only 100 grams and is accurate to +/- 1.0%. In addition, it easily bolts up to your existing E*Thirteen crankset so 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 has a 2-year manufacturer’s warranty. Also, with Bluetooth SMART, you can use it with your favorite indoor training program or app.
Key Product Details
Compatibility:
This XCADEY power meter fits E*Thirteen 15-spline direct mount cranksets. Regarding chainrings, it requires a 104 BCD 4-bolt MTB chainring. It is compatible with bikes that use Boost spacing and chainrings that use a 3 mm offset. 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, active temperature compensation, ANT+ and Bluetooth compatibility.
Advice From Our Staff:
There are not a lot of power meter options for E*Thirteen cranks and the XCADEY not only fits, but is affordable and measures power from both legs. Therefore, we think it’s a great option for E*Thirteen cranks.
Compatibility
Crankset: The XCADEY E*Thirteen MTB Power Meter fits E*Thirteen 15-spline direct mount cranksets.
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)
The smallest 104x4 chainring you can use on a XCADEY MTB power meter is a 30T round or 32T oval.
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.
