ive been told that mid bb is just us pushed out of the bearing cups is this true, please help me as ive just bought a frame with a mid bb and currently have spanish so i need to no  :LolLolLolLol:

BrianP:
morning dbj,

yeah for a 19mm BB, the bearings in a mid bb are just the R12 bearings out of a stanadrd US BB, eg profile, etc. without the cups.

dunno if this is the case with a regular 22mm US BB tho...

Bp.

ps hope ur grans doing better.
