Bike spokes

Common types of Bike spokes

Straight-gauge spokes

These are the same width for their entire length (typically 2mm or 14-gauge). Simple and inexpensive, plain-gauge spokes are often used to build wheels where weight-saving is not an issue, such as heavy-duty BMX, Mountain bike or touring bike hoops. They offer a slightly stiffer ride because of their thicker cross—section.

Single-butted spokes

These spokes are slightly thicker in the neck of the spoke (the part closest to the hub) for extra strength and stiffness when building disc-brake wheels, and for heavier applications. They are slightly heavier than double-butted or plain-gauge spokes.

Double-butted spokes

These are lightweight spokes that are thinner in the middle (e.g going from 2mm to 1.8mm and back to 2mm again) to save weight and reduce ride stiffness, without compromising on wheel strength. Double-butted spokes are lighter and more expensive than plain-gauge or single-butted spokes, and in their thinnest guises (e.g down to 1.5mm) may not be suitable for Mountain bike riding.

Aero bladed spokes

These have a flattened cross-section to reduce wind resistance. For time-trial bikes and race-oriented road bikes.

Straight-pull spokes

These have no ‘j-bend’ at the flared (hub) end, the idea being that eliminated the bend cuts out a potential weak point in the wheel build, and also saves weight through the spoke being fractionally shorter (which adds up in a wheel with 20 or so spokes). They require a dedicated hub.

How to Measure Different Spokes

J hook spoke length

J- hook spoke length is measured from the inside of the elbow to the threaded end as shown in picture below.

Straight pull spoke length

Straight pull spoke length is measured from the inside of the spoke head to the threaded end as shown in picture below.

How are Spokes Made

All our spokes are manufactured from the highest grade Stainless Steel or mid carbon galvanised steel, which ensures the optimum combination of strength and performance.

The spoke material arrives in 500 kg coils of wire and is fed into a spoke machine that straightens the wire before cutting it to length. It then forms the head before forming the bend and rolling the thread as it ejects the 'spoke' from the machine.
