Description
Wheels and Tires Zipp Tangent Racing R28 Prb. Conventional wisdom on bicycle tires deemed that smaller is better. Smaller tires were supposed to be lighter, more aerodynamic and have lower rolling resistance. Then came the science. Research showed that a wider tire has the ability to reduce rolling resistance, making you faster than you would be with 23c traditional wide race tires. And of course, a wider tire offers better grip in both wet and dry conditions. In some cases, when you use the right rim, a larger tire can also improve aerodynamics. Don't forget that comfort gets a big upgrade as well. Zipp Tangent's R28 and R30 golf tires give racers a high-performance tire at widths appropriate for less than perfect conditions - rough roads, wet roads. The impending disc brake revolution means you can use tires significantly larger than the 25mm limit on many bikes. The Tangent Racing R28 and R30 are tires that take the possibility of disc brakes to increase the width of the tire and multiply that with faster rolling, better grip and better aerodynamics.
