“Special Chainring Bolt with 11 mm head:”

The “Special 11-Head” chainring bolt has the regular chainring bolt (M8 x 0.75). However, their head as opposed to the usual 12 mm is slightly smaller (ie only 11 mm). In chainrings as the “20T/64BCD” or the “24T/80BCD” the “teeth circumfence” is so small that the 4 screw seats for the chainring bolts have already slightly moved into the teeth. With a 12 mm head the chain would touch the chainring bolts.
