[#7800959]

I'm told that I need a 122 mm, JIS square BB-UN55 bb for my crank

I can only seem to find 73x122.5 bb's though... will that work ok?

This is just for a pub bike so I'm trying to keep costs loooow rather that buying a new crank etc etc

Yes
(assuming your frame is 73mm of course)
Oh and for a 2nd edit, you don't need anything as posh as a un55, a un26 will do fine ๐Ÿ™‚

Yes it is, & thanks...

& my edit; I can get a un55 for under a tenner, I'm willing to allow such extravagance is this instance 8)

(Thanks again!)

If it's for a SS make sure that both crank and bb are JIS (mixing interface shapes makes the crank sit proud and can bork the chainline)

I have a box full of Shimano square Bb, will have a look if there is a 122. I know I have a 127.
