Designed specifically for e-Bikes and longer wear, our steel e-Rings are 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.
MTN E-Rings are ‘female‘ threaded for an M8 chain ring bolt. The M8 CR bolt threads directly into the 104BCD ring for better motor clearance.
Mounting – LOGOS ALWAYS FACE OUTWARD!
