Pete (Penseyres) and I used 'sew-ups' for years in our tandem racing programs. But this was some 30 years ago (do they still make the Del Mundo heavy-duty tire?; that was our tire of choice for the tandem). We switched to clinchers 15 or 20 years ago for many reasons: ease of use being the primary one. We also found that, most of the time, clinchers were a bit safer under most circumstances. When we'd have a flat on sew-ups there wasn't much warning so that we could slow down; where as, we found with clinchers there is a much better chance to ride out a slow leak a bit longer. Ionically, the last race we did where we used sew-ups was the Davis D.C. (many, many years ago when there was a mass start, and it was more of a 'race' for the front group). We used Fast Tac (sp?) for glue but heard of issues with using that as a "sew-up" glue. However, most conventional sew-up glues will soften on high speed descents under tandem application. What are using for tire and glue? I'm pretty sure our Davis DC crash would have the same outcome with sew-ups if we had hit, say, a piece of glass and flatted quickly on that fast (and twisty) descent. Some days your number comes up no matter what you're using, eh? Thanks for the comment Gary. Pete (Penseyres) and I used
