Product Description
Zipp Alloy Stem Top Cap With T25 Bolt
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.
Zipp Alloy Stem Top Cap With T25 Bolt
The new Zipp Stem Top Cap and Bolt are designed to work specifically with Zipp stems.
The 8g-aluminum cap and 9g-bolt are the same as those used on bikes built for Zipp-sponsored professional teams.
The bolt has a T25 Torx head for ease of adjustment and so you need only one tool for your cockpit.
