Tubular tires, overall, provide a better ride (there's a reason that more pros use tubulars!). Quite simply, tubular tires have higher tire pressures, and therefore, lower rolling resistance. This also provides them with a more comfortable ride. Additionally, tubular rims are on average about 100 grams lighter than clincher rims, and tubular tires are about 30-50 grams lighter than the clincher tire/tube combination. So you will also gain a weight advantage by riding tubulars. Practically speaking, they also tend to be more puncture resistant, and pinch-flats are non-existent with tubulars because of the very nature of their construction.<?:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /> The main advantages of clincher tires is that they are less expensive overall than tubulars, and they are somewhat easier to change (particularly on the fly). The performance gap between clinchers and tubulars has decreased in recent years. A good clincher tire performs almost as well as a tubular these days. So what you choose to ride, in the end, really is a matter of personal preference with respect to juggling these pros and cons. Accomplished RAAM riders are almost all riding clincher tires. Though most riders recognized that tubular tires provide a better performance, they also noted that the difference between the two types of tires has lessened over the past number of years. Thus they chose to ride clinchers primarily because of their increased convenience, both for training and for racing. There were a couple of tubular tire hold-outs, but they were clearly in the minority among RAAM riders. The most common brand of tire among those who rode clinchers was Continental. It was the clear favourite, with the Grand Prix series being the preferred model. With respect to tubulars, Vittoria was clearly the company of choice. There are a number of choices to consider when choosing a wheelset for your bike. In the end, much of it seems to come down to personal preference, based on a finite number of variables, such as weight and aerodynamics. As with your frame selection, the wheels you select for your bike should be chosen with your particular events and goals firmly in mind.
