Spoke information

Spoke cutting & threading

With so many hub and rim combinations available it can be hard to get the correct spoke length for a wheel build, particularly small wheels. We can produce spokes as short as 25mm and cut in 1mm increments in either 12g, 13g or 14g.

Contact us if you require anything not listed on this website.


We can also make spokes to match your samples. Contact us for information.


Spoke lengths ?

Use a spoke calculator to determine your spoke length. Links for calculators below.

Breaking spokes ?

We have enquiries from people wanting a few spokes to replace broken ones; more than two broken spokes is a cause for concern if there are no specific reasons for failure (such as spokes damaged by chain ) there could be a problem with the spokes, spoke tension, hub spoke hole diameter or a combination of  any or all three  advice is to;

  1. Use quality branded spokes, such as Sapim or DT Swiss.
  2. Tension spokes correctly according to hub and rim combination. Spokes that are too loose are likely to fail and break.
  3. Use a spoke washer if the diameter of the hub spoke hole is more than 0.3mm of the spoke diameter.

Measuring ERD  (effective rim diameter)

Measuring (ERD) Effective Rim Diameter

An essential measurement when determining spoke lengths.

There are many databases containing measurements of popular rim ERDs. These may be correct and accurate however, it is always best to take your own measurements, at least the first time you work with a hub or rim you have not used before. 


ERD is the wheel rim diameter measured at the nipple seats in the rim spoke holes, plus the thickness of the two nipple heads. See the photo above. If you need more information of how to measure why not read the Park Tools article here 


Plain gauge Spokes

Spokes for use in any type of general purpose or heavy-duty application. They have a constant diameter throughout their length, which makes them slightly heavier than butted spokes. Straight gauge spokes offer a stiffer ride than single or double butted spokes because of their thicker cross section.

Butted spokes

Butted spokes can be identified by a change in diameter between the neck and the body of the spoke. 

Single butted spokes are slightly heavier than double butted, but are also slightly less expensive. Single and double butted spokes are used for similar applications. Single butted spokes with 2.3mm neck diameters are also useful for wheels to be rebuilt with used hubs that have worn mounting holes in the flanges. 

  • We offer Sapim Strong single butted spokes from stock


Brass spoke washers fit on to the spoke before lacing the wheel if the hub spoke hole diameter is greater than 0.3mm of the spoke diameter. These washers reduce the load change movements that lead to spoke elbow failure

Spoke nipples

Our 14g spoke prices include silver brass 12mm long nipples 12g & 13g spokes are supplied with 14mm long nipples.

Longer nipples are used on thicker rims.

“Proloc" are nipples with a thread lock incorporated


Brass spoke Nipples

Brass nipples are durable and offer high strength under extreme tension and in corrosive environments. Brass nipples are available in silver and black finish.

 Available in 12 / 14 / 16mm lengths.

12g, 13g, 14g nipples available in a selection of diameters to suit wheel rim requirements.


Alloy spoke Nipples

Aluminium nipples are ultra-light and offer optimal weight reduction for minimal cost.

We offer, DT Swiss' high-precision aluminium nipples which  are available in silver finish and are Swiss made. DT Swiss 14g Silver Alloy nipple 12mm long.


You could save 22grams on a 32 spoke wheel using alloy nipples in comparison to using brass nipples.
