The Wolf Tooth 104 BCD bash ring is one of the few available that is properly sized for the rings it is being used with, especially in the case of 30t and smaller chainrings. If you like the rough stuff, log hopping, bouldering on your bike or occasionally like to see if you can break your bike on the gnarlies, at least protect that beautiful Wolf Tooth 104 or 64 BCD ring!
Sizing: Fits 64 BCD x 26t and 28t as well as the 104 x 30t chainrings.
These fit only cranksets with an outside ""big ring"" mounting position. They will not fit dedicated double cranks with no flat surface on the outside of the 104 spider arms.
When used with a 64 BCD ring, we recommend mounting it with Wolf Tooth 6mm bolts. *** Note: Orient the head of the bolt to the inside to provide clearance for the chain. ***
When used with a 104 x 30t ring, 10mm bolts are required. We recommend the Wolf Tooth 10mm bolts.
When used with a 104 x 32 or 34t ring, use the stock 8mm bolts & nuts that came with your crankset. This is the stock bolts length used on most triple cranksets to hold the middle and big rings on.
