The majority of spoke nipples we supply are from Sapim the link button below takes you to their website to explain the types and features of Sapim nipples.
What is a spoke nipple?
The spoke nipple is screwed onto a spoke at the rim of a wheel.
Nipples are threaded on the inside just like any typical nut and bolt combination. Turning the nipple using the appropriate tool increases or decreases the spoke tension.
Nipples fit through holes in the rim, so it is important to check the size of the rim holes. The common bicycle size rim hole and matching nipple is 4mm. Some rim holes and nipples can be 5mm or even 6mm on ebikes or cargo bikes.
Nipples must match the spoke size, so a 12g nipple will not fit a 13g spoke and vice versa.
Many different types of nipples are available, including internal nipples that sit entirely within the rim and can only be adjusted by removing the tyre.
How do I know the nipple size?
Using a Vernier caliper to measure a spoke nipple.
3.42mm would be measuring the spoke key needed.
Spoke nipple measurement
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
Our 14g spokes include silver brass 12mm long nipples 12g & 13g spokes are supplied with 14mm long nipples.
Longer nipples are used on thicker or deeper rims.
Spoke nipple diameter sizes can be 4mm, 5mm, or 6mm depending upon the rim holes in your rim.
Some nipples are available with a thread lock incorporated
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.
Aluminium nipples are ultra-light and offer optimal weight reduction for minimal cost.
We offer Sapim in a variety of colors also , DT Swiss aluminium nipples which are available in silver finish.
You could save 22grams on a 32 spoke wheel using alloy nipples in comparison to using brass nipples like for like.
