A spoke wrench that fits three common nipple sizes. A spoke wrench or spoke key is a small wrench or tool used to adjust the tension in the spokes of a tension-spoked wheel.A spoke wrench is sometimes called a nipple wrench, as it is the spoke nipple – not the spoke – that is turned in the process of changing the tension of a spoke.
However, machine-built wheels are rarely as satisfactory as handbuilt wheels, partly because it is uneconomical to allow the machine to spend long enough on each wheel for a perfect result but also because most machines leave spokes with some residual twist. Machine-built wheels can be identified by their lacing pattern (if it is not radial ...
A spoke nipple holds a bicycle wheel's rim to each spoke. The spoke nipple is a headed cylinder with threading on the inside through part of its length (there is an unthreaded lead-in nearest the "flats"). Traditionally, the nipples fit in holes in the rim, so that the head of the nipple is on the outermost part of the rim, while the other end ...
An adjustable spanner (UK and most other English-speaking countries), also called a shifting spanner (Australia and New Zealand) [1] or adjustable wrench (US and Canada), [a] is any of various styles of spanner (wrench) with a movable jaw, allowing it to be used with different sizes of fastener head (nut, bolt, etc.) rather than just one fastener size, as with a conventional fixed spanner.
This type of washer is especially effective as a lock washer when used with a soft substrate, such as aluminium or plastic, [8] and can resist rotation more than a plain washer on hard surfaces, as the tension between washer and the surface is applied over a much smaller area (the teeth). There are four types: internal, external, combination ...
The Comstar wheel, sometimes referred to as Com-stars or stylised as ComStar, [1] [2] was a composite motorcycle wheel that Honda fitted to many of its motorcycles from 1977 [3] [4] to the mid 1980s. Its design allowed it the option of being fitted with tubeless tyres and its use on the Honda CX500 was the first time tubeless tyres had been ...
The Steffey motorcycle in 1902, essentially a bicycle with a two-stroke engine attached, used wooden, rims with wire spokes. [1] This style of wheel evolved into a stouter motorcycle-specific wheel, still with spokes, up to the 1960s and beyond. [2]: 134 In April, 1922, Borrani started production of motorcycle wheels with an aluminium rim. [3]
Typically, each spoke is pretensioned to about 100 pounds of force, on an unloaded wheel. When the bicycle is loaded with a rider, then the spokes below the hub have less tension. With every rotation of the wheel, there is repeatedly changes in the spoke tension that can contribute to broken spokes because of fatigue failures.
