Bottom Bracket Query...

(1/2) > >>

SteBurns:
Is a mid bottom bracket an American bottom bracket, but without the bearing cups?

Hopefully I can save myself some cash :)

bobbbbsy:
mids 19 or 22 and usa is 50mm... :-\

SteBurns:
I see... I was told you could tap the bearings out of the American BB cups and use them in a mid BB frame. I knew it was too good to be true lol.

bof:
I'm sure the bearings will fit just knock them out of the cups and push them in the mid bb. Its the Spanish bb that is a different size.

john4130:
it should work but not always, give it a try and see if they will tap in without too much effort.
