Conventional wisdom on bicycle tires has held that smaller is better. Smaller tires were supposed to be lighter, more aerodynamic and have lower rolling resistance. Then came science. Research has shown that a larger tire has the ability to cut rolling resistance, making you faster than you would be with a traditional 23c-wide racing tire. And of course, a larger tire offers improved grip in dry and wet conditions. In some cases, when using the right rim, a bigger tire also can improve aerodynamics. Let’s not forget that comfort gets a big upgrade as well. The Zipp Tangente Course R28 tire give riders a high-performance clincher at widths suitable for less than perfect conditions—rough roads, wet roads. The looming disc brake revolution will mean that you can run tires significantly larger than the 25mm limit on many bikes. The Tangente Course R28 tires take disc brakes’ opportunity for increased tire width and multiplies that with faster rolling, better grip and improved aerodynamics. - High-performance sport and training clincher tire - 28mm width - 120tpi nylon casing - Nylon puncture protection layer under tread - 260 grams (R28), 306 grams (R30) - 33.15 watts of rolling resistance @ 40kph (with Zipp butyl tube) - 70 ShA durometer rubber (Shore A) - New water-siping tread pattern - Comfortable in rough conditions

Speaking for itself, Raddler is the radder version of our famed Riddler tread pattern. It combines the expeditious efficiency of a short-knob centerline with get-rad traction of chunky outer knobs. Let's call it a semi-slick, but one designed to increase confidence while you're pushing the limits of gravel. Raddler is an excellent choice for loose terrain where traction takes priority, but efficiency is never far behind. Lean it over, take the inside line, brake late, and stay pinned with the Raddler. SG2 PUNCTURE PROTECTION: These tires are available with our all-new SG2 Puncture Protection, which is a lightweight nylon insert that provides bead-to-bead coverage and ensures every area of the tire is defended against slashes and punctures. As events become progressively rougher and cyclists pedal farther, gravel gets tougher. It only makes sense for gravel tires to become tougher as well. - Nylon fibers have a flat profile, which reduces the amount of rubber needed to fill the gaps between fibers and minimizes weight. - Protected SG2 gravel tires feature a 120tpi casing, which improves suppleness compared to a traditional 60tpi tire. - SG2 was specifically designed to be a puncture protection layer, but it also improves air retention and eliminates seeping at the sidewall. FEATURES: - Short-knob center tread cuts down on rolling resistance while still providing enough bite for out-of-the-saddle traction. - Center and intermediate knobs on the Raddler are slightly taller than those of the original Riddler, thereby increasing tire lifespan without negatively affecting rolling efficiency. - Tall, toothy outer lugs ensure your favorite gravel descent doesn't unravel in the final corner. - Single-ply 60tpi casing provides dependable protection at a minimal weight. - Available with black or tan sidewalls in 40mm and 44mm widths. - All Raddler tires are TCS tubeless compatible.
