Back now - Sorry I had to rush off.
Ah yes I can see now that it is MR 21531. The bill for the three bearings and postage was for £23 in April 2007, so probably about £7 each. I remember now putting two of them on the Drive Side to replace the 14mm width bearing in the picture above.

As they are RF specific and the Signature series instructions say they might have a grease port .
Have to try get them out of the cups and off the axle at some point .

been fun looking though... makes me want to find a cheap fix all the more though
Well done for finding them, even if you end up sorting things another way - every day's a learning day
As for ISIS in general, you made a good point earlier regarding how long it was around for!
The actual balls in the bearing are tiny little things compared to Square Taper. I ended up buying a ludicrously expensive Stronglight Twister Titanium for that Kula Primo of mine.... with a view to it lasting longer. :roll: Seems ok so far - oops, that'll be a bad omen!
