My journey toward becoming a winter commuter has suggested to me a point I never considered before. Could it be that tubulars (nice wide ones of course) may have some advantages for winter riding? My struggle to find adequate gloves has made it obvious that hands can get pretty cold, even in the 30s F. With partially numb hands, I think it would be a lot easier to change a tubular that to change a tube in a clincher - particularly a wire bead one. Could it be that this was part of the reason that racers used tubulars for most of the 20th century, particularly the early decades when there was no or little support? Races were often run in brutal conditions, and hands could become all but frozen. The story of Tullio Campagnolo's frozen hands on the Croce d'Aune and the subsequent invention of the QR is legend. Can you imagine him trying to get a wire bead clincher off the rim with a tire lever under those conditions?
