125mm / 126mm cartridge bottom brackets

[retro-rich]

interesting... I'll look into that

Only obvious concern is I'd be restricting the degree to which the drive-side threads of the B/Bracket screwed into the B/B shell on the frame by at least 3mm...

I know that on a standard B/B the pedalling tightens rather than loosens, but is this likely to be a problem?

Not too sure tbh, I just had one spacer on mine and it seems ok, there is plenty of thread on the bb shell, but perhaps someone more experienced with these will chip in.

If you can just remount the guard as mentioned then at least it should save you a few quid on buying more parts.
