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).
