Sigeyi AXO Praxis Road Power Meter

The Sigeyi AXO Praxis Road Power Meter is a spider-based power meter that is compatible with Praxis 3-bolt road cranksets. The Sigeyi power meter measures power from both legs, is accurate to +/- 1.0% and is lightweight at only 105 grams. In addition, it easily bolts up to your existing Praxis 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:

The Sigeyi Praxis Road Power Meter is compatible with Praxis direct mount cranksets. Direct mount cranksets have drive-side crank arms that can be removed from the crankset. In addition, if you were to view the backside of the crank, you would see three small bolts or screws that secure the crank arm to the spider or chainring. Regarding chainrings, it fits 110 BCD 5-bolt or 110 BCD 4-bolt chainrings based on the version ordered. 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.

Advice From Our Staff:

The Sigeyi is a great way to add power to Praxis 3-bolt road 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.

 

Options For This Power Meter

BCD: This power meter is available in the following BCDs in order to fit your choice of chainring sizes:

  • 110 5-Bolt | 110 4-Bolt

Compatibility

Crankset: The Sigeyi Praxis Road Power Meter is compatible with Praxis direct mount cranksets. Direct mount cranksets (left image) have drive-side crank arms that can be removed from the crankset. In addition, if you were to view the backside of the crank, you would see three small bolts or screws that secure the crank arm to the spider or chainring.

Standard cranksets (right image) have a one-piece drive-side crank arm and spider. That is, the crank arm and spider are one solid piece of aluminum.

Most modern Praxis cranksets are direct mount. This includes Zayante M30, Alba M30 and Zayante Carbon M30. It's very important you confirm you have a direct mount version where the drive-side crank arm can be removed. If you are not sure, please send us some images of your crankset and we would be happy to confirm for you.

Praxis Direct Mount vs. Standard Crankset

Chainrings: This power meter is compatible with 110 BCD 5-bolt or 110 BCD 4-bolt chainrings based on the version ordered. In many cases, you can use your existing chainrings assuming they use the same configuration as the power meter you order.

Important chainring notes:

1) Some Praxis cranksets come equipped with direct mount chainrings, while others come with LevaTime 160/104 BCD chainrings. In either case, you will need to purchase new Praxis Works Buzz Road Chainrings or Praxis Works Buzz Sport Road Chainrings as direct mount or LevaTime chainrings won't work with a Sigeyi power meter. If you are not sure if your current chainrings will fit, please contact us so we can help.

2) This power meter is not compatible with Praxis 110x5 48/32 chainrings. This is because the 32T chainring is smaller than the diameter of the power meter. 110x5 50/34 is the smallest chainring that will work.
