This page contains the MTB chainrings we recommend for use with our power2max MTB power meters. power2max MTB power meters use a standard 104 BCD, 4-bolt configuration (direct mount chainrings found on many new mountain bikes will not work). We have extensively tested all of these rings with power2max power meters and they work flawlessly. You can order these chainrings with or without chainring bolts. Please note, the smallest MTB chainring that will fit on a power2max MTB power meter is a 32T round, or a 34T oval.
