• It'll be tight! It's tight enough on my old, 'narrow stays & tyres' PC with a BB spindle 2mm longer than standard. Gap to stay is currently approx. 2mm (see post #3065, previous page), so must have been 1mm with previous (SG75) BB.
    There's an indentation/scuff to my powder coat in the location where the spider used to rub the chainstay under load when using the old BB. Scuff was flatted off/polished out a bit before I fitted the new BB but you can still see the indentation.
