Sigeyi AXO Shimano MTB Power Meter - 1X 100×8
The Sigeyi AXO Shimano MTB Power Meter is a spider-based power meter that is compatible with Shimano direct mount 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 Shimano 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.

Advice From Our Staff:
The Sigeyi is a great way to add power to Shimano MTB direct mount cranksets. It measures power from both legs, is accurate and affordable. 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.
