You need 5/32" if memory serves, but I might be wrong. I usually use these: http://www.ebay.co.uk/itm/1-PR-BICY...sleisure_cycling_bikeparts_SR&hash=item3cc018 Tell the seller what they are for, this bunch know about bikes! If you prefer loose ball bearings make sure you get the hardest grade and by the pack ( Cheaper but, by the time you need to do this you are usually in deep trouble and have another four or five frames hanging up ready to start on!) Have a look here:http://www.ebay.co.uk/itm/Weldtite-...arts_SR&var=&hash=item6fc36b26ca#ht_979wt_879

Beg or borrow a micrometer (cheap as chips!) and measure things you take off. Like most things worth the effort the ball bearings on bikes stayed pretty much standard for a hundred years or so. (You have already learned rule 1, by the way, - keep all the old bits until you have checked them against the new bits!)

Take the time to look here : http://sheldonbrown.com/ . Sheldon Brown (now sadly dead) knew just about everything worth knowing about bicycles and this site is a mine of information. (Don't be put off by it being an american site, he enjoyed british bikes and you will find a great deal of info here.

As a general rule:
5/32" for headsets (the only exception Ive come across are 1930/40s Elswicks which take billions of 1/8")
1/4" for rear hub and BB
3/16" for front hubs
1/8" for pedals.

Got the measurements needed 22 1/4 for bb 25 5/32 for head set

I bought some of these off ebay. Did BB and rear wheel. Also got these for the front bearing. Enough for a few more rebuilds yet. They also have these which I might send for soon.
