Burgtec Shimano E-Bike Steel Thick Thin Chainring

The outside-fit version of Burgtec's 104mm BCD steel e-bike chainring is for spiders that require the ring on their outside face. Steel construction focuses on durability, while the thick/thin profile is designed to help retain the chain.

This listing is the 34t option in Burgtec Black. Check the spider and mounting position on your bike, even when it uses a Shimano motor; the spider determines whether inside or outside fit is correct.

The threaded holes take M8 x 0.75mm x 8mm chainring bolts, and those bolts are included.
