Zero stretch so far at 400 miles on one set.

The other is too new.

They should work dandy with Open 4 CDs.

I gave up on Challenge PRs acouple of years ago, as they grew and grew.

I ended up giving a couple of sets up at the time as they were too wide.

I do have a set of Challenge Strada Biancas on my Bilenky and they are 700x30. They are dreamy, but some folks online have reported blow out issues with these when mounted on rims that are too wide.

I have them on Dyads with no complaints whatsoever.

They don't seem to care a whit, as long as it isn't deep sand or loose river rock.

I'll see if I can't get some fotos for you this weekend.
