• hi mate, not quite sure what you mean?

    if i use a new chainring on my fsa cranks, it will make the chain sit 3-4mm futhur out from the centre of the bike...

    to compensate this, i would have to have a narrower bottom bracket - and i was under the impression that the standard fuji BB was 103mm?

    (unless its actually 110mm?, and then yeah - changing to a 107mm JIS sq taper, Should bring a replacement chainring back into line)
