Praxis CR Chainring Direct Mount Wave 1x 40T - Black

Praxis direct mount chainring is designed specifically to mate with the 3-Bolt Direct Mount interface cranks.

Whether you're riding Cyclo Cross in mud or grinding gravel, Praxis 1X rings are ready for action with the 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 1X rings are machined of top quality plate 7075 T6 aluminium for superior stiffness and hard anodized to take a beating.

For use with Direct Mount cranks with the 3-Bolt SRAM style interface
