TOP FAQ

Do these rings fit my crank?

These rings are designed for eBikes using a 4-bolt 104BCD spider. (Bolt Circle Diameter) 

So please measure/check that you have 104BCD and NOT the smaller 94BCD.

Do these rings come with chainring bolts?

No, these rings mount using male M8 chainring bolts.

Our steel MTN e-rings are female threaded and the M8 bolt threads directly into the ring.

Praxis does not sell these bolts.

Can I use these rings if I do not have an eBike?

These rings are not recommended for analog (non-e) bikes.
