• What a coincidence: Thats what I've just come online to look at. Trying to squeeze a 104 outer onto the middle. I'm thinking about dremelling the shoulders on the chainset down.

    Trying to put together a parts bin 1x chainset for my MTB, before I get spendy.

  • I'm thinking about dremelling the shoulders on the chainset down.

    Wouldn't it make more sense to cut the chainring, i.e. the consumable part?

  • I considered it but at present the chainring is worth more than the chainset, plus I have only 1 non-ramped chainring, but a few chainsets (in this size). Plus if I wear the chainring out I can buy another and pop it straight on.

    Its an FC-M540 (Deore I think, Octalink too so quite old) so no biggie if I destroy it. Just gotta check Ihave the correct BB before Dremelling (although, probably not until after Easter).
