AB-Lock Nipple DSN 14Gx16mm BLK

AB-Lock is a process where a dual compound, adhesive liquid is injected into the nipple thread during manufacture, this compound then dries and remains dormant until a spoke is threaded through the compound.
By threading the nipple onto the spoke the adhesive is activated and begins to cure. (it is recommended that wheels using AB-Lock be built in "one sitting" and not "finished" the following day).
However, re-truing the wheel is still possible even after the adhesive has cured completely, with only a minimal percentage decrease of its thread holding capability.
