• I thought Mavic BBs were JIS.

  • OK, is that good news or bad news? :) Sorry I know nothing of Shimano and JIS

    Its surely not going to be as easy as letting me use a Shimano BBUN55 is it, that would be great but seems too easy and simple. If yes from what I can see they come in axle lengths of 107mm, 110, 113, 115, 118 so maybe one of those?.

    Edit, hmm all the Shimano BB's I see are BSA threaded but the frame I want to fit this Starfish to is a late 80's Italian bike with Italian threaded BB and a 68 shell width, so I seem like I'm trying to cross streams again, is there any Italian threaded square taper JIS BB's with a 68 shell width?

    @MCamb I did wonder about that, maybe a new one will be too fat but a more used chainring will be worn to fit :)....thanks, to be honest I can fiddle with chains, its the BB I'm more worried about at this point.
