XCADEY XPOWER-S GEN2 SRAM 8-Bolt MTB Power Meter
The XCADEY XPOWER-S GEN2 SRAM 8-Bolt MTB Power Meter is compatible with SRAM 8-bolt MTB cranksets. It measures power from both legs, is accurate to +/- 1.0% and is lightweight at only 100 grams. In addition, it easily bolts up to your existing SRAM crankset. Therefore, there is no need to buy new cranks or replace your bottom bracket. The power meter also 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.
Key Product Details
Compatibility:
This XCADEY fits SRAM direct mount 8-bolt cranksets. It uses 104×4 bolt pattern chainrings, which are different than the direct mount chainrings found on many SRAM MTB cranksets. It works with bikes that use Boost spacing. These bikes usually feature a 52 mm chainline and 148 mm rear hubs. With the included 3mm spacers, it can also work on bikes with Standard spacing. 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 SRAM 8-Bolt MTB Power Meter is a great way to add power to SRAM 8-bolt MTB cranksets. This power meter is an affordable choice for those who ride a mountain bike with a Boost or Standard chainline.
Other Versions to Consider
XCADEY SRAM 3-Bolt: We also have the XCADEY XPOWER-S GEN2 SRAM MTB Power Meter which fits SRAM 3-bolt MTB cranksets.
Compatibility
Crankset: The XCADEY SRAM MTB Power Meter fits SRAM direct mount 8-bolt cranksets. This includes the new SRAM Transmission T-Type 8-bolt cranksets. Before purchasing, please confirm that your crankset uses the 8-bolt interface as shown below.
Chainline: Out of the box, this power meter is compatible with boost chainlines and replicates the 3 mm offset found on boost direct-mount chainrings. With the included 3 mm spacers, it is also compatible with bikes that have standard chainlines and replicates the 6 mm offset found on standard direct mount chainrings.
Chainrings: This power meter requires a 104 BCD 4-bolt MTB chainring (which is different than the direct mount chainrings found on many SRAM MTB cranksets). If you don't already have a 4-bolt chainring, you can order one on this page along with the power meter. If you purchase a new chainring, we will bolt it on to your power meter before shipping, which will make installation that much easier when you receive it.
Please note, if you are using this power meter on a SRAM T-Type Transmission drivetrain, we recommend the Wolf Tooth Components 1x 104 BCD MTB Chainring, which is compatible with these 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.
