• Steel eRing for eBikes. • ‘Female‘ thread. • Wave™ Tech. • Cold-Forged 4130 Steel. • Must use 'Clutch' style Derailleur. • 10, 11 & 12 Speed compatible.
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.
