Hi,
I am thinking of getting these cranks for a singlespeed bike: http://www.ribblecycles.co.uk/sp/road-t ... AMPCHAR890

My question is what BB do I use with the cups? Ideally I want a smaller chainline than you get with the traditional campag BB double (ideally want 40-42mm) so was thinking of using the 103mm BB if possible? -OR am I better off using standard campag double cranks (non-Ultra-torque) with a 103mm BB if that is possible?

If anyone has these type cranks I would be interested in what BB and what chainline you have.

Thanks for any help..

    UT chainline is UT chainline..

    You fit the cups, the bearings are on the spindle which are connected to the crankarms/spider. You don't need a square taper BB.
