Just by coincidence, I also just bought a set of Conti Top Touring 2000's, in th 28 X 1 1/4 size.

They are replacing 700C x 32's, and that's what the LBS gave me. They had a tag on them saying 700X32, but the lettering on the tire has the actual size.

I put the front one on, it seems a little narrower than the 32, but that's OK. The only thing was it seemed pretty tight getting it on, but once on it is fine. I havn't put the rear one on yet I'm waiting a while to see how the front one does, although I've got close to 200kms on it with no probalems, so I'll probably go ahead and put the other one on.
