Sigeyi AXO SRAM 8-Bolt MTB Power Meter

The Sigeyi AXO SRAM 8-Bolt MTB Power Meter is a spider-based power meter that is compatible with SRAM 8-bolt MTB cranksets. This 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.
