I'm looking for a couple of retro triple chainsets to get a few more gears on mine and my brothers road bikes for touring in the highlands over the summer. Shimano preferrably but open to others.
Either road type - 80s 90s up to ultegra 6500/dura ace 7700 era nothing more modern than that
OR mtb e.g. the nice deore LX 550 ones or same era XT.
If you have a british threaded BB that is the right length to match that would be fantastic also.
