Maybe I’m being dim … My road bike has 50:38 front chain set with a 12-27 rear cassette. I tend to like spinning and find I’m erring to the lower gears. I have an old middleburn chain set triple. Could I run 44:34 on it and get a decent chainline etc? I have a 9 speed Campag set up so would the chain work ok?

Thanks

I do it, have the larger ringed XT on two bikes. The only difficulty you MAY have is shifting to the outer ring, on my Uncle John the mech is right at its limits to shift, I should take a spacer ou of th BB but I’ve never got round to it.

What about a 50:34 road compact instead?

I know your trying to use stuff you have to hand, but its a faff 🙁 thing tend to work just ok but a bit of a pain. For £52 if you’ve got it I’d just stick one of these 48/34s on. You’d get bored spinning a 44 ring out anyway.

I’ve used an old LX triple on a touring bike with 9sp Campag and an even older LX 7sp front mech. Is the Campag front shifter ratcheted? If so it should work with pretty much any old mech. Indexed might be a different story…
