Praxis mtb 1X Wave Tech 104 BCD chainring - 32t

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.

• STEEL RING FOR 104 Bolt circle diameter - (NOT for smaller 94BCD 'Levo SL' spiders!)
• These e-rings are 104BCD 'female' threaded. An M8 CR male bolt threads directly into this threaded e-ring for engine clearance.
