The 104 BCD bashring can be added to the crankset to protect a 104 or 64 BCD chainring.
Properly sized to fit 104 or 64 BCD chainring
Two sizes for ultimate protection: smaller 26-30t (132 mm diameter) and mid-sized 32t-34t (148 mm diameter).
These are compatible with all triple 104 BCD cranksets and mount in the “big ring” position
They are compatible with double cranksets that have flat outfacing mounting tabs, like XTR M980. However, many 2x specific cranks, like Shimano XT M785, have a profiled outer surface on the mounting tab so our bashring cannot be mounted on that non-flat surface.
Chainring bolt requirements for this bashring
104 x 30t - 10mm bolts are required for use with the bashring.
Other 104 BCD sizes - you will need 8mm bolts (stock size that comes on 3x cranksets holding the middle and big rings on). Wolf Tooth does not make these.
When using with the 64 BCD you will need6mm bolts to mount the bashring.Note: Orient the head of the bolt to the inside to provide clearance for the chain (bolts will go in backwards).
