>>1355527ANYWAY, here's the TLDR of all that (ignore the first post if you want):
1. Do modern front derailleurs have wider cages or something? My chain seems to fucking rub in at least one gear that I'm on while on a particular chainring. This can sometimes require "trimming" as Sheldon Brown refers to it (having to slightly adjust the front derailleur to prevent the chain rubbing when you're in a particular rear gear). I shouldn't have to fucking do this. Maybe if I get a newer front derailleur, it might have a wider cage and I can avoid this problem? The front derailleur I bought off eBay does specifically say "narrow" on it...
2. My bottom bracket spindle length appears to be 124.5mm. Weirdly this isn't a length offered by Shimano with their ubiquitous BB-UN55 cartridge English threaded bottom bracket which would probably be a good replacement for my ancient-style one. Their two largest sizes are 127mm and 122mm - quite a difference. Should I just measure my chainline and see if I could get away with one of these? Maybe I'll need to use spacers or something.
