Sigeyi AXO Cannondale Road Power Meter

The Sigeyi AXO Cannondale Road Power Meter is a spider-based power meter that is compatible with all models of Cannondale’s Hollowgram cranks: SI, SISL, and SISL2. It is also compatible with the Cannondale One crankset. 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 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.

Advice From Our Staff:

The Sigeyi is a great way to add power to Cannondale 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.

Compatibility

Cranksets: This Sigeyi power meter is compatible with all models of Cannondale’s Hollowgram cranks: SI, SISL, and SISL2. It is also compatible with the Cannondale One crankset.

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

Please note, some Cannondale cranksets come equipped 120 BCD chainrings or with direct mount chainrings (spiderings). In these cases, you will need to purchase a new 5-bolt chainring for use with your power meter. We recommend Praxis chainrings with this power meter (found on our Chainrings page).

1 review for Sigeyi AXO Cannondale Road Power Meter
  1. Joe (verified owner)

    I recently added a Sigeyi AXO Power Meter and Praxis Works Buzz Chainrings to my 2013 Cannondale Hi-Mod Evo. Replacing the stock Cannondale SpideRings took about an hour, however it was not the first time I have swapped out chainrings on a Hollowgram crankset. One needs some special tools to do the job, including a Cannondale crank arm extractor set, a Spidering lock ring tool and a really big torque wrench! If you don’t already have the tools and experience it might be just as economical to let your LBS do the job for you. Once installed, the Sigeyi Power Meter was very easy to set up using the Sigeyi iPhone app and it paired with my Wahoo Bolt V2 without a hitch. I like the appearance of the Sigeyi unit as well as the fact that it tells me my left/right leg power balance. I also like the fact that the Sigeyi uses a rechargeable battery so I won’t be littering the planet with 2032 coin batteries. When paired with my SRAM 11 speed eTap groupset, the shifting of the Praxis Works Buzz chainrings is super fast and super crisp, far superior to the shifting of the SpideRings. I couldn’t be happier with my upgrade and with Power Meter City in general!
