Wolf-tooth Wolf Tooth 104 BCD Chain Guard

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).

Compatibility

These are for use with 104 BCD chainrings or 64 BCD chainrings on 104 BCD crankset

• 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.
• These work great with the 104 BCD Elliptical 32t ring. They will work with the 34t as well, but at the
  max diameter a few teeth will
  extend just beyond the bashring.

Chainring bolt requirements for this bashring

• 104 x 30 Tooth – 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 need 6mm
  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).
