I have at least one Zeus catalog reprint from Chuck, so I'll check that. Meantime, the 2000 BB came with at least a couple more balls than needed, so I'll measure one of the extra balls. I also have an NOS Zeus Criterium BB or two, so if bearings were included, I'll check that bearing size.

I'm a bit surprised Zeus would use 7/32 bearing, as that is so close to 1/4", you'd think they could just reposition the races slightly and use the standard balls. The 2000 axle spins smoothly in the Criterium cups, so I'm inclined to ride them. I doubt it matters if the bearings track a bit differently in the steel cups. What would be more a concern is if they don't track correctly on the axle race. Probably the only way to really tell that is to put a moderate amount of mileage on it, then pull the BB for inspection. Anyone have any experience with whether slightly mismatched BB parts will change tracking on axle or cups or both?

Of course the best solution would be if someone has Zeus 2000 Ti English cups they want to trade for French. That seems a long shot, but I'd gladly do that trade if anyone wants to.

Well, I actually used the bearings packaged with the 2000 BB, which seem to run quite smoothly in the Criterium cups. I have three different editi ons of Sutherland's and none mention any Zeus BB having anything other th an 1/4" balls. The only 7/32 BB bearings mentioned are 1990 Campy Record. But then, Sutherland's isn't infallible.

I'll go back and measure some of the 2000 BB bearings. Of course it is po ssible both 2000 and Criterium used 7/32.

I have 2 Zeus 2000 BBs here; they both use 7/32" balls. The spindle and cups are both Titanium, with press-fitted ground and polished steel races .

But I agree, they are very nice, certainly nicer than Campy's Super Record Ti BBs.

Stronglight also made a Ti BB, but their's was arguable even nicer, since the spindle (except for the taper where the arms mount) was a wider diameter than a standard BB spindle. Sealed cartridge bearings were held by Aluminum cups, making a very strong and light unit.
