Spoke wrench
A spoke wrench or spoke key is a small wrench or tool utilized to correct the tension in the spokes of a sulky wheel,bike wheels, wheelchair wheel, or analogous. A spoke wrench is occasionally named a nipple wrench, as it’s the spoke nipple – not the spoke – that’s turned in the action of modifying the tension of a spoke.
Spoke nipples are commonly T-shaped cross-sectional, with an inner thread running component of the direction through the hole that runs along the spoke nipple’s main axis. A spoke nipple stays in a hole drilled radially through the wheel’s rim, and the nipple is threaded onto the outer thread of a spoke. The spoke itself is rigid (fixed), at its other end, through a hole in the hub. The spoke and nipple are functionally equal to a bolt and a nut. Even so, contrary to a regular nut-and-bolt pair, a spoke and nipple don’t join two components (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 in utilization is square in cross-sectional. Spoke keys possibly 3 or 4-sided; the last mentioned 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 flats of the nipple. It’s more improbable to round off the nipple than the 3-sided type, but is slower to utilize.

Basic sizes of spoke nipples (flat-to-flat) include:
- 0.127″ (3.23 mm) (DT/Wheelsmith nipples)
- 0.130″ (3.30 mm) (most European)
- 0.136″ (3.45 mm) (most oriental)
These values for size don’t show the inside diameter, which is important for fitting to the spokes.
Utilization
A spoke wrench is utilized in the construction, sustentation, or repair of hand-built or machine-built spoked wheels. The goal in such activity is to bring the wheel (closer) to a state of true – that is , a wheel in which the rim is: an exact circle concentric with the axis of the axle in the hub; and, planar, in a mode that the plane of the rim is centered laterally between the two extremes of the axle where it is supported in a frame.
By increasing or decreasing the tension of individual spokes, or groups of spokes, around the circumference, a wheelsmith can adjust for local deviations from true – for example. wobbles, or hops.

Never realized how comfortable it was to trim your bicycle wheels, should have bought Avenir Pro Spoke Wrench Set years ago. Just recall to think backwards: turn spokes anticlockwise to tighten.
Yes Ronald you are right Avenir Pro Spoke Wrench Set is upper-class that will plausibly last me for the rest of my biking days.
A spoke wrench is easy to utilize. But you’ve to understand how to do it.Begin with the round and side.
