DT standard brass nipples fit most makes of spokes and are available in black and silver. 100% Swiss made.

Black spoke nipples are available the  "prolock" version.  Prolock nipples contain a special locking compound which sets into place once the wheel is built and prevents the spoke from loosening.  The wheel can still be trued if necessary.  Prolock are not recommended for use with Revolution spokes as the spokes tend to twist when truing them due to the locking compound, thicker spokes can resist this.

Pack sizes as follows:
Black prolock nipples: box of 100
Silver nipples: box of 72

All are 12mm length.
