Circuit/Rennen 4 Bolt Chain Ring

We teamed up with Rennen Designs to get this custom 4 bolt 1/8 Circuit Chain Ring.

These are proudly made in the USA out of aircraft quality 7075-T6 Aluminum ( 83% stronger than 6061)

Threaded ring, it does need a back bolt.

Ive been personally riding this same ring for 8 years all while smashing and grinding on out with zero issues. 

This is one tough ring. 

It pairs well with the Profile Racing 4 Bolt spider. 

Sold single or as a combo with the spider.
