Product Details

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.

Key Features
  • 104 BCD. Will mount to most any 4-arm 104BCD MTB crank
  • New Wave Technology tooth profile. Alternating teeth for better chain retention
  • These e-rings are 104BCD ‘female‘ threaded. A male M8 CR bolt threads directly into this threaded e-ring for motor clearance
  • 10/11sp Shimano/KMC/SRAM, 11sp SRAM XX1 chain
  • Cold forged High Grade 4130 grade steel
  • Rear derailleur Must use a 'CLUTCH' type rear derailleur. eg Shimano Shadow or SRAM Type 2
  • In very rough terrain, or just for pure security, we still recommend use of an upper guide
