Hello Larry, You need no intro, your shops' collection is a good one. I met you a decade ago, but it's nice to know you better. I got replacement dial belts for the Barelli competition rollers from Kreitler rollers (tel 800-333-5782). I believe Teresa makes them custom. We took a while measuring the size. We ordered belts 1/4" thick 27" round, though the old one was 33". They come kinda short, stretch the plastic to make them fit. I describe it on my web site roller page: "The equation for the belts: A+B=X+C-D. A is one-half the dial circumf.; B is one-half the cable cog circumf.; C is dial center to cog center times two; D is stretch variable of minus 15 percent." I hope that helps, otherwise call me. We're looking to construct a platform round them, so people can get on and off easier. We plan to use them. Our NYC messengers want to do races, they call it the "Goldsprint." In fact, many of them are into classic lightweight stuff. Dave Perry
