Is filing a chainring worth doing.

[Banjo]

New chain started chain sucking on my worn inner chainring so fitted new chain ring. Its now sucking on the big (50T) ring. Rather than buy a new ring is there a case for filing the drive edge of the teeth on the big ring to extend its life ?

There is a case - it would save you money!

There is also a question - would it work?

 

[Yellow Saddle]

Yes, there is a case for it. If you were on a tour or a multi-stage race and your chainring starts sucking, you would dress the tips with the file on your Leatherman. That's just a get-home fix though.Those filed chainrings are now out-of-pitch with the chain and will accelerate your chain wear considerably.

New big one ordered from chain Reaction to go with the new chain ,new cassette and new inner ring all recently fitted. . Its done several thousand kilometres so I cant complain too much. At least the BB seems smoothe for now.
