1,000,000 Spokes made on the premises each week !

PLEASE NOTE ...

Lengths of bend will be supplied as near to requested size as possible. It must be remembered that stainless steel does not bend as tightly as galvanised material, so not all requested bends are attainable.

Spokes supplied are replacements not replicas. Some spokes may vary in length of bend or angle from original. When assembled and tensioned these spokes will bed and sit correctly in the hub.

IMPORTANT: For your safety ...

Check spoke nipples supplied to ensure that they are the correct size for the spokes when fitted and will hold tensions.

Check nipple holes in the rim to ensure that the nipples supplied have suitable clearance.

Check hub and rim for damage before assembling the wheel.

Ensure when assembling the wheel that the spokes are tensioned correctly to the manufacturer’s specification. Ensure regular checks of the tension in the wheels to avoid spoke breakage.


Central Wheel Components manufacture its own brand of C.W.C. Spokes and Nipples. These are available in various materials and gauges and can be supplied in any quantity from 28 for one off wheels to 100,000+ for original equipment or replacement wheel suppliers.

Which size ?

Over the years we've amassed a good knowledge of which spokes fit which bikes. Even so, it is always advisable to provide a sample spoke with your order and to supply details on the length, gauge, angle and length of bend of spokes required (see diagram below).

Spoke Measurement Instructions

When ordering butted or double butted spokes both gauges should be given. For example, if the spoke tapers from 8 to 10 gauge, write it as 8/10g.

Sizing spokes is quite easy if you follow this chart :Spoked Wheel

  Spoke Gauges are as follows:   12 = 2.60mm (.104” dia)
  10 = 3.20mm (.124” dia)
  9 = 3.60mm (.142” dia)
  8 = 4.00mm (.156” dia)
  7 = 4.45mm (.171” dia)
  6 = 4.87mm (.192” dia)
  5 = 5.15mm (.203” dia)
  4 = 5.70mm (.224” dia)

Metric gauge sizes available on bulk orders - 3.00mm, 3.50mm, 4.50mm

Galvanised has long been the traditional material for spokes, but today stainless steel is far more popular and gives a better, longer lasting finish.

Unpolished Stainless Steel spokes resemble galvanised spokes with the added benefit of being corrosion resistant.

Polished Stainless Steel gives spokes a chrome-like appearance, but without the same level of maintenance.

Butted and Double Butted Spokes are supplied in stainless steel only.

SM Pro "Bull Dog" Spokes are made from a high tensile stainless steel developed for the motocross market which is hard wearing and will not stretch with use.

All galvanised spoke sets are supplied with zinc-plated steel nipples, stainless steel spoke sets with nickel plated brass nipples.

Be aware that similar materials can seize together over time, so if you would like advice on materials do please ask. It should be remembered that stainless steel will not bend to the same degree as galvanised steel.

Providing the essential link between hub and rim.

The primary role of spokes is to give strength to the wheel, but the criss-cross effect of gleaming metal also looks visually pleasing.

Central Wheel Components manufacture galvanised and stainless steel spokes, the latter being supplied either polished or unpolished.

The material and finish chosen for a specific job will depend on several factors - the type of bike, its age and your personal preferences. The information below will help you decide.

Spokes vary greatly in length and diameter, some wheels featuring butted spokes. These aren't a uniform thickness but taper down from one diameter to another and in rare cases you'll find double butted spokes, which are thicker at each end for greater strength.

Our spoke sets for a one-off wheel comprise 40 spokes with nipples, though obviously we're happy to supply any number of spokes, whether it's 10 or 100,000.

Manufacturing spokes

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.

Stocks of blank spokes (headed but not threaded or bent) are made and held in stock ready to be bent and cut down for our smaller orders or spoke sets.

Butted spokes are made from wire which is the thickness of the butted end but are intentionally cut short. The spokes are then hammered out to length, reducing the diameter of all except the butted end.

The final part of the process is to clean and polish the spokes. Large vibrating metal bowls full of polishing compound and ceramic pellets clean the spokes through abrasive action. Similar vibrating bowls containing maize apply the final polish.
