File my cranks for bling or get one that fits?

BigLee1

I`ve bought a middleburn middle chainring and it doesn`t fit my FSA cranks so, do I just take it back to the shop, 40 miles round trip, or do I file the 1mm off each arm so it does fit?

If I do will it conspire to kill me? the bloody thing fits where the outer ring goes perfectly

if you want one that fits correctly you will need an FSA one.

Most people file the ring.

Ah, so the FSA cranks and rings are a unique size then? The buggers!

File the ring, it's what we did on the Daughters when we made it one-by at the front using an old steel ring....she now has an EnvY ally ring.

nope just that the shoulder diameters change on cranks.

common issue.

I think I`ll file my crank, my ring appears very hard! Or is it worth the effort?
