Whether you’re cylo-crossing in mud or grinding gravel, Praxis 1x rings are ready for action with their Wave™ tooth profile.

Licensed and developed in conjunction with Mountain Racing Products, the Wave™ 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. Plus Praxis’s 1x rings are machined of top-quality plate 7075 T6 aluminum for superior stiffness and are hard-anodized to take a beating.
