  • I think you can get Campag bbs down to 103mm. It sounds really narrow but the taper is different to Shimano.

    Chain does look a bit short. What's it like on the smaller ring? Looks like a big jump which might end up a bit slack if the derailleur is short. You could always go 1x at the front if it's too much for the rear derailleur.

  • Yes going for a 103, 111 seems to be an oft quoted figure but I think old mirage and chorus may have used the shorter one. Good point on the chain/chainset I know what you mean. I was keen to get the tricolour 600 as its a mech I grew up with!
