I had a set of UKAI rims that I bought as a lot deal from a closing shop. I bought the 3 for $50 tubulars from Yellow Jersey. I put them on the wheel and inflated to about 40psi and left them under the bed for a couple of weeks and just pulled them out yesterday. I haven't tried riding them dry but I could probably do that tonight. When put in the stand there dosen't seem to be a bulge or hop. My main concern is having the tire come loose, I know it's by the valvestem, but I just don't want to go down because of a rolled tire. The mechanic from Yellow Jersey made it seem like this is a common occurence but for some reason I just don't think so.
