Does anyone know the dimensions or a bearing part number for replacement
Campagnolo ultra torque BB bearings?

I read in one forum the dimensions are 37x25x7mm, but I'd like to
confirm before purchasing and taking the BB apart to find what I bought
is NQR.

Cheers,
James.

I've just bought a pair branded campagnolo but made in china the dimensions are ODxIDxW

37x25x6 mm I've checked with my normal supplier simply bearings and they don't do them. you can buy them on wiggle

Thanks. I worked that out back in February, 2011. The bearings are
replaced back then are still fine now in May, 2016. 5 years for BB
bearings that carry me on average more than 10,000km per year. 50,000km
so far, and going strong. No noises or slop. Remarkable crank and BB
design.

At least one BB30 bearing on my son's bike is shot after maybe 10,000km total. I get better service out of ordinary Ultegra BBs. My son's bike was my fast rain bike (before it became a hand-me-down), so it did get wet a lot which may have contributed to its early demise.
