Zipp is an American company that is best known for designing, manufacturing, and marketing carbon-composite bicycle wheels for road cycling, triathlons, track racing, and mountain biking.
The company's product range also includes handlebars, stems, seat posts, tires, inner tubes, handlebar tape, and bags.
In 1988, the company was founded by motorsports engineer Leigh Sargent and released its first carbon fiber disc wheel.
Zipp was acquired by bicycle component manufacturer Sram in November 2007. In October 2010, Zipp relocated from its original design and manufacturing facility in Speedway, Indiana to an expanded site in Indianapolis.
The company was first to market with dimpled discs and rims (they also own the patent), to induce boundary layer turbulence and prevent detached airflow in crosswinds.
Zipp has done pioneering research in aerodynamics, using various high tech wind tunnels, and has published advanced papers in this area.
The company was also the first to produce disc wheels, deep section rims, and cranksets using carbon fiber technology.
With its newly refined drop shape, the Service Course SL-80 provides comfortable and efficient positions on the bar tops, brake hoods or down in the drops.
The bar allows a neutral wrist position on the drops and a flat brake-hood transition.
This minimizes the need for up-rotated bars.
Drops are angled outward by 4 degrees, reducing wrist strain.
Named after its 80mm reach to bring the hoods and control levers back where you want them.
The ergonomic 125mm drop places the angled drop position where you can easily reach it while maintaining a neutral wrist angle.
The SL-80’s rounded bar top is clip compatible.
