Designed specifically for e-Bikes and for longer wear, the steel e-Rings are cold forged from 4130 high quality steel with a beautiful black oxide finish. Licensed and developed in collaboration with Mountain Racing Products, the Wave pattern tooth profile applies an alternating lateral force to each chain link to actively hold the chain in the ring – going beyond narrow/wide implementations that rely only on friction, leaving room for mud, debris and grit to exit. The Wave design also wears more slowly than competing designs, spreading the load over a larger surface area.
