Wolf Tooth 104 BCD Bash Ring
The Wolf Tooth 104 BCD Bash Ring is a sturdy, precision-machined protection ring that can be added to your crankset to protect high-end 104 or 64 BCD chainrings. It is available in two sizes for a wide range of chainring sizes.
Choose between a smaller 26-30t (132 mm diameter) and mid-sized 32t-34t (148 mm diameter) bash ring.
Compatibility
- These are for use with 104 BCD chainrings or 64 BCD chainrings on 104 BCD cranksets.
- Compatible with all triple 104 BCD cranksets and mount in the “big ring” position.
- 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 bash ring 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 bash ring.
- Chainring bolt requirements for this bash ring:
- 104 x 30t – 10mm bolts are required for use with the bash ring.
- 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 bash ring.
