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.
