Praxis MTB 1x Wave Rings 104 BCD

Tough enough for Enduro and Downhill, yet also weight conscious for XC riding, Praxis MTN Wave™ rings are machined from 7075 T6 aluminium and hard anodized to take a beating. Licensed and developed in conjunction with Mountain Racing Products, the Wave™ pattern tooth profile applies alternating lateral force to each chain link to actively retain the chain to the ring – going beyond narrow/wide implementations that rely solely on friction, while allowing room for mud, debris, and grit to escape. The Wave™ design also wears more slowly than competing designs by spreading the load over larger surface areas.
