Sigeyi AXO Cannondale MTB Power Meter

The Sigeyi AXO Cannondale MTB Power Meter is a spider-based power meter that is compatible with Cannondale 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 Cannondale 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.

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.

Advice From Our Staff:

The Sigeyi is a great way to add power to your Cannondale MTB crankset. 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.

 

Options For This Power Meter

Chainline and BCD: This power meter is available in the following versions:

  • 1X Cannondale AI | 104 BCD
  • 1X Boost | 104 BCD

The Cannondale AI chainline is 55 mm. This is how Sigeyi MTB Cannondale power meters are configured. If your Cannondale crankset uses Boost instead (52 mm), your power meter will come with a 3 mm adapter, converting the chainline to Boost. This power meter will not work on bikes with standard (49 mm) chainlines.

Lock Ring Tool: This page also allows you to purchase your power meter with the Sigeyi Lock Ring Tool for Cannondale, which is required for installation. We recommend you order it unless you already own one.

Compatibility

Crankset: The Sigeyi Cannondale MTB Power Meter is compatible with Cannondale SI, SISL or SISL2 cranksets. It is also compatible with the Cannondale One crankset.

Chainrings: This power meter requires a 104 BCD 4-bolt MTB chainring (which is different than the direct mount chainrings found on many Cannondale MTB cranksets). If you don't already have a 4-bolt chainring, we offer several to choose from.

The smallest chainring you can use on a Sigeyi MTB power meter is a 30T round or 32T oval.
