rarman1:

sorry chaps but am i to belive that US/MID BB are the same

darkersomeday:
yes sir,
the mid bottom bracket is designed to use profile 19mm axle sixed sized bearings without the alloy cups the would normally sit in the frame,

primo usa 22m axle sized bearings are a little bigger and wont fit in the mid bb,

what crank and bottom bracket do you have/intend to fit?

rarman1:

bugger got a new sunday frame from winstanleys, already own primo powerbites, am i stuffed

harris:
if you go to a bearing supplies ,tell them the bb size and your axle size then they might match them.

rarman1:
that sounds good as i really like my powerbites, do you know of a bearing shop in london dan ?
