Designed specifically for e-Bikes and longer wear, our steel e-Rings are cold forged from 4130 high-quality steel with a beautiful black oxide finish. Licensed and developed in partnership with Mountain Racing Products, the Wave™ design's tooth profile applies an alternating lateral force to each chain link to actively hold the chain to the ring-going beyond narrow/widely implemented implementations that rely solely on friction, leaving room for mud, debris and grit to escape. The Wave™ design also wears slower than competing designs, distributing the load over a wider area.
