Cold forged from 4130 high-grade steel with a nice black oxide finish.  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.
