They are standard bolts. You can use a granny ring bolts (from 64bcd chainring) or use the ones that connect middle and big ring from 3X crank. You can also buy them from us in the Bolts tab. Pick “Long” ones. Other sizes like 34 and 36T use “short” bolts.

It also does not require a chain tensioner when using in the single-speed application. Riding out of the saddle on the uphill will become more pleasant. These chainrings also help you to recover after knee injuries as pedaling becomes smoother and less exhausting. It is the most advanced oval chainring currently on the market.

10, 11 or 12spd chain for a geared bike or 6-8 spd one for SS (1/8″ also fits). If used in a 1×9 drivetrain – a 10spd chain must be used to obtain the performance. (yes – 10spd chain will work great on 9spd cassette)

Chainguide needed?

No. But if you want one then chain guide should have 2 teeth more capacity than nominal oval ring size.
