Deore Middle ring doesn't fit!

Who's being difficult - Shimano or Truvativ?

There's not much of an overlap, and I'll probably just take a hacksaw and file to the shoulders of the tabs on the crank.

RRRRRGHHH, though. I thought bolt diameters aside, chainrings were chingrings were chainrings?

RRRRRGHHH!!!

Seeing as we're able to mix'n'match everyone elses bits, i'd say it's Truvativ to blame. A bit of filing(usually more than expected)will sort it, not that you should really have to.

file the chainring not the crank IMO

there are two different shimano fittings ( at least) for 104 bcd chainrings - the shoulder on teh crank is a mm or two smaller. I don't understand which one is which but it has caught me out

*kneels, crying, shaking fists at the sky*

Why, Shimano!? For God's sake, WHY??!?!?

tj, normally I'd agree, file the cheaper, consumeable bit, but the chainring's steel, cranks are ally, and I'd rather not have to do it again. I can't imagine that what I'm proposing to file off is going to affect strength in any meaningful way. It's only about 1/2 mm off the shoulder stepping down to the tab itself.

This has come after a number of other bike frustrations, hence the melodrama.

To add to the mix, FSA rings vary a bit too. Had to file a cheap Shimano crank to get an FSA bit on once.
