67:, with an internal thread running part of the way through the hole that runs along the spoke nipple's principal axis. A spoke nipple rests in a hole drilled radially through the wheel's rim, and the nipple is threaded onto the external thread of a spoke. The spoke itself is fixed, at its other end, through a hole in the hub. The spoke and nipple are functionally equivalent to a bolt and a nut. However, unlike a typical nut-and-bolt pair, a spoke and nipple do not join two parts (the rim and the hub) so much as bridge them, under tension.

The area of the nipple around which the spoke wrench, or key, is fitted is generally square in cross-section. The tool grips the square of the nipple on either 3 or 4 sides; the latter type has a small cutout to enable it to be fitted over a spoke, after which it may be slid along to engage all four

and results in a stronger wheel. On modern bicycles, considerable space is needed for multi-speed clusters of gears as well as disc brakes; this means that there are usually two lengths of spokes on each wheel, one length per side. The act of shifting over the centerline of the rim between axle

A further goal it is to adjust the tension of the spokes so that they are brought as close to equal tension on each side of a wheel as is possible given the initial properties of the wheel's rim. This act of equalizing tension is called

flats of the nipple. Gripping all four sides of the nipple results in less chance of rounding off the nipple than the 3-sided type, but is slower to use.

planar, such that the plane of the rim is centered laterally between the two extremes of the axle where it is supported in a frame.
