Bicycle wheel To accomplish this, wheel designs are employing lighter rim materials, moving the spoke nipples to the hub or using lighter nipples such as aluminum. Note however that rotational inertia is a factor only during acceleration (and deceleration/braking). At constant speed, aerodynamics are a significant factor. For climbing, total mass remains important. See Bicycle performance for more detail. The hub flanges of modern tension-spoked bicycle wheels are always spaced wider than where the spokes attach to the rim. When viewed in cross section, the spokes and hub form a triangle, a structure that is stiff both vertically and laterally. In three
Fuchs wheel the hub and the rim for reasons of style and appearance. While our design was well-adapted to the shape of the series vehicles now being retired, the shape developed by Mr. Porsche Jr. appears more harmonious with the new vehicle". Ferdinand Porsche Jr based this design change off a 'kleeblatt', or four leaf clover. Fuchsfelge AG was responsible for many technological advancements in the creation of automotive wheels around the late 1960s and early 1970s; notably the creation of the first forged wheel on behalf of Porsche, and the first series-production aluminium wheel, which was used on the 1972 Mercedes
