Description

Cut the drag.

Zipp's first product in the late '80s was the disc wheel, jumping into the spotlight as a serious wheel that could cheat wind unlike anything the cycling world had seen before. Today, through professional rider feedback, the use of advanced composite technologies, and extensive wind tunnel testing, Zipp continues its mission of building the fastest disc wheels on the planet. With the introduction of the Super-9 Disc Track Carbon Clincher, Zipp's Super line continues, marking this latest innovation in disc wheel design as its fastest wheel to date. It balances aerodynamics, stiffness, light weight, and durability with the convenience and low rolling-resistance that only a clincher is able to provide.

Throughout extensive wind tunnel testing during Zipp's "carbon clincher project," its engineers discovered that, aerodynamically speaking, clinchers are significantly faster than tubulars. The transition from the tire surface to the rim surface allows for the airflow to stay attached, which reduces pressure drag and makes you go faster. This could only be achieved using a carbon clincher design, as the carefully molded brake track more closely follows the contour of the clincher tire than that of a tubular. The reshaped brake tracks actually tip inward slightly, rather than aligning parallel to each other, with the disc bulging out at its widest point just below the braking surface. This keeps the clincher tucked down into the relatively wide, 26.42mm tire bed. Besides an aerodynamic advantage, the added width between the clincher hook beads increases air volume in the tire, which means a lower chance of pinch-flatting.

The Super-9 carbon clincher still has a dimpling pattern that's specific to the 900, which helps smooth the air flow in order to minimize drag. Its Aerodynamic Boundary Layer Control (ABLC) carbon fiber skins are embossed with over 4900 golf ball-like dimples in five different sizes patterned to force the airflow to form less turbulent boundary layers. You get less drag in all wind angles, as well as less buffeting of the disc in crosswinds.

The hub used is Zipp's durable track hub, with internals manufactured using a high-voltage wire EDM technology. This specialized manufacturing process, usually reserved for avionics and Formula One gearboxes, lets Zipp machine 50% harder materials at tolerances 20 times greater than standard machining and heat treating. The result is a sub-200g hub that can handle the torque of a four-cylinder car engine.

The Zipp Super-9 Disc Track Carbon Clincher Wheel tips the scales at around 1,370 grams, and it's available in the color White.
