Hey all,

Recently picked up a Raleigh steel frame and am having a little trouble determining the bottom bracket type.

It was a width of 68mm, internal diameter of 34mm, and the adjustable cup is right hand threaded and the independent cup is left hand threaded (tightens when turning counter-clockwise). I believe it may be swiss but that seems odd for a Raleigh.

Hoping to find an outboard bearing bottom bracket so I can use some modern cranks with a 24 mm spindle instead of square tapered ones which are on it now. Anybody got an idea of what type of bottom bracket it is? And where to find a decent outboard bearing bottom bracket? Thanks!
