MTB Chainrings for power2max and Sigeyi

This page contains the MTB chainrings we recommend for use with our power2max and Sigeyi MTB power meters. power2max and Sigeyi power meters require 104 BCD, 4-bolt chainrings. (Direct mount chainrings found on many new mountain bikes will not work.) We have tested all of these rings and they work great with these power meters. You can order these chainrings with or without chainring bolts. Please note, the smallest chainring that will fit on a power2max or Sigeyi MTB power meter is a 30T round or a 32T oval.

Additional MTB Chainrings for power2max and Sigeyi Info:


We carry both road and oval absoluteBlack MTB chainrings for MTB. These are some of our favorite chainrings due to their unique look, low weight and high rigidity. They are designed and manufactured in Europe and are made using the very best aluminum alloy available. They are compatible with 10-, 11- and 12-speed drivetrains (except Shimano 12-speed chains).

Race Face

For Race Face, we have two MTB Chainrings for power2max or Sigeyi power meters. We have the 1x 104 MTB Chainring which is compatible with 10-, 11- and 12-speed drivetrains (except Shimano 12-speed). We also have the 1x 104 MTB Shimano 12-Speed version for Shimano users. These chainrings use Race Face’s narrow-wide technology as well as 7075-T6 aerospace grade aluminum which makes them strong and lightweight.


For Praxis we have the Praxis Works MTN 1x 104 BCD Wave Tech Chainring. This chainring is made from 7075 T6 aluminum, is hard anodized and features the Praxis Wave pattern tooth profile for maximum chain retention. It is compatible with 10-, 11- and 12-speed drivetrains.


Many customers need to change out their SRAM direct mount chainring for a power2max or Sigeyi compatible version and our SRAM X-SYNC 2 Chainring is a great option. It’s the same as the direct mount version, but just features a 104 BCD. Therefore, it’s perfectly suited for the power2max/Sigeyi power meter. It is compatible with 11- and 12-speed drivetrains.

Wolf Tooth

Wolf Tooth makes our best-selling power2max and Sigeyi MTB chainrings. We have round and oval and as well as Shimano 12-speed versions. These chainrings are affordable, strong and lightweight. In addition, they feature Wolf Tooth’s Drop-Stop technology. This is an alternating wide/narrow tooth pattern that prevents chain derailment. They are compatible with 10-, 11- and 12-speed drivetrains.
