Reynolds Forty Six Wheelset - Tubular

Product Descriptions

RealCyclist Description: Reality for most of us means that we have to choose one wheelset for all conditions. You know the tradeoffs; deeper wheels are faster in the wind, lighter wheels are faster up hills. And regardless of which way you go, strength is always paramount. Looking at the options, most people would best off on mid-depth wheels -- light enough not to be a penalty uphill, but deep enough to eke out some advantages everywhere else. And this is where the Reynolds Forty Six Carbon Tubular Wheelset excels. These wheels have been ridden in cobblestone and hilly classics alike and at the Tour de France.The Forty Six is an update of Reynolds popular DV46T wheelset. They have nearly the same rim shape, but the wheels are faster because of a subtle aerodynamic improvement. It's known as a Swirl Lip Generator and is a patented Reynolds feature you'll find on their shallow- and mid-depth carbon-fiber rims. The SLGs are two tiny lips on either side of the narrow edge of the rim. If you didn't know better, you might think they were parting lines that weren't sanded down after the rim came out of the mold. There's no sanding forgotten, and they are hardly an accident. The SLG creates turbulence that helps the airflow reattach faster behind, after passing over the rim. They also decrease sideways air force on the rim, and in so doing, make your bike easier to steer in crosswinds. This means it takes less concentration and less strength to pilot the bike so you can devote more concentration and more strength to going fast.Another change is Reynolds' new CTg brake track. C is for Cryo, Tg for glass transition temperature. As you know, heat build-up is not a good thing at the brake track. For tubulars, heat build-up can lead to softening of the glue holding the tire to the rim and melting brake pads in the heat. The new CTg tracks are the result of a new resin system and a new laminate structure. In regular riding ...faster than the Thirty Two, but light enough for rolling race courses...
