how are chainring bolts length measured

by admin on September 20, 2013

Our chainring bolts come in a few different sizes.

The best thing to do is remove the chainring bolts from your crankset and measure them against our picture here.

The length of the part to consider is the outside of the nut. This is the part where the force is applied.
The inner bolt only needs to be long enough to get sufficient tightness.
