Bicycle wheel other exotic spoke lacing patterns (such as "crow's foot", which is essentially a mix of radial and tangential lacing) as well as innovative hub geometries. Most of these designs take advantage of new high-strength materials or manufacturing methods to improve wheel performance. As with any structure, however, practical usefulness is not always agreed, and often nonstandard wheel designs may be opted for solely aesthetic reasons. There are three aspects of wheel geometry which must be brought into adjustment in order to true a wheel. "Lateral truing" refers to elimination of local deviations of the rim to the left or right
Ferris wheel as a triple Ferris wheel, Triple Giant Wheel, or Triple Tree Wheel, it was in height. The Santa Clara ride, renamed Triple Wheel in post-Marriott years, closed on 1 September 1997.
