Thanks Edd

All rear hubs use 9 1/4" balls each side.

All Shimano front hubs and 99% of others use 10 3/16" balls each side.

Dura-Ace front hubs have eleven 3/16" balls in each cup.

home depot carries an inexpensive measuring tool from Genereal for measuring ball bearings-try
harris cyclery online for grade 25 and probably CB's bearing article. check out the chainguard at
"DIY" in bike tech.most mechanics develope a small measured increment slowly. today an 1/8" is vague
but next week .0001" will look like a yard. balls are tough 'cause looking at both sides at once is
an acquired skill best circumvented with the measuring tool. sure beats ordering
1/8 for 5/32 or worse installing the wrong size screwing the hub up AND EVEN WORSE THE RETARDS OUT
IN THE WHAREHOUSE MIGHT SEND ONE FOR THE OTHER!!

Even bigger! Are they brass, too?

^^^^^^^^ Peter - I've read your comments trash-talking about Shimano for years now
without saying anything, but this really goes too far!
