BB Help?

Ultra Lord

Hurts. Requires Money. And is nerdy.
Howdy ya'll

My mate is getting a new crankset (saint), and the bike shop guy was asking asking how far apart the bottom bracket cups are? Now I thought you only needed to know the width of the bb shell, and the diameter. He said something about the width being either 150mm or 135mm? Either I've completely misheard the shop guy, or theres something im failing to see here.

Please help.

He'd be talking about rear end spacing if it were 150mm / 135mm... This would determine the width you need your spindle to be for chain line to be right.
