- Anyone ever filed down the plastic bit on a Shimano 10spd chainring?
But please file the rings, not the cranks!
Just wondering why?
The older cranks spider arms have a small ‘lip’ for the chainring to sit on, but the newer ones that take the composite rings don’t have this. So my thinking is that if the newer ones have done away with it, what’s the harm in filing it off the old ones? And, surely its better to file the cranks once, than the ring each time you replace them?Posted 4 years ago
