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

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
Cranksets: The Sigeyi SRAM Road Power Meter is compatible with SRAM S-900, Force 1, Force 22, Rival 1, Rival 22 and CX1 cranks with a 3-bolt interface. This power meter does NOT fit Cane Creek eeWing cranks.
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.
- Note 1 - Please note, the 110 BCD 4-Bolt version is compatible with all Shimano 4-bolt chainrings, including Ultegra 8100 and DURA-ACE 9200 chainrings.
- Note 2 - Some SRAM cranksets come equipped with direct mount chainrings. In this case, you will need to purchase new chainrings as direct mount chainrings won't work with a power meter spider. We have several chainrings to choose from on our Chainrings page.
- Note 3 - This power meter is not compatible with SRAM Red cranksets as these use a 1-piece drive-side crank arm and spider.
What is BCD?: BCD (bolt circle diameter) is simply the diameter of a circle that passes through the centers of the bolt holes in your chainring. The BCD is usually stamped right on the chainring as either 110 or 130. It is important to know what BCD your crankset is because assuming you want to use your existing chainrings on your new power meter, you need to order the correct BCD.
