I'm pretty sure they are a 20mm diameter, so a standard Odyssey one should fit  :daumenhoch:  If it's just the bearings that are shot then there should be a number on the seal that you can take to a bearing shop and a 141 replacement  :daumenhoch:

Cheers lads the bearing casings have been fitted with a hammer & there shot to bits & one of the bearings is crap too. I put an engineers ruler across the centre hole & it says 21mm. they are redline prolines i got off motomag :-\

Ben, I had a similar problem with one of my BB's, I got my mate to put them on a lathe and skim the outer surface then I wnet to work with wet and dry before polishing them - the outers look like new now although the insides are not so pretty but no-one sees those when they are on.

BTW, on your bearings is there a very thin top-hat style washer pressed in?

Hi cant see any top hat washer pressed in although im not entirley sure what your on about. i could probably get away with new bearing cups but again i dont know what size one's to get :-\

alans sells 20mm bearings that allow you to use them in a spanish bb
