Sigeyi AXO SRAM MTB Power Meter

Sigeyi AXO SRAM MTB Power Meter

The Sigeyi AXO SRAM MTB Power Meter is a spider-based power meter that is compatible with SRAM 3-bolt MTB cranksets. The Sigeyi power meter measures power from both legs, is accurate to +/- 1.0% and is lightweight at only 83 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 300 hours of ride time, auto-zero functionality (so your data is always accurate), left and right leg power balance and a 2-year manufacturers warranty. Of course, you also get Bluetooth SMART. This allows you to use the power meter with your favorite indoor training program or app.

Key Product Details

Compatibility:

This Sigeyi fits SRAM direct mount 3-bolt cranksets. Regarding chainrings, it 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 104 BCD 4-bolt chainring, we offer several to choose from. See Compatibility tab for more information.

Power Measurement:

The Sigeyi 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%, 300 hours of battery life, rechargeable battery, very lightweight, left/right power balance, ANT+ and Bluetooth compatibility, auto-zero (automatic calibration). See Specs tab for more information.

In addition, since it bolts on to your existing crankset, there is no need to buy new cranks or change bottom brackets. It is also lightweight which makes it a great option for cyclists looking to minimize added weight.
