Sapim ensures that aluminum nipples receive a special coating that reduce the friction. The Sapim coating is a unique process that applies on the thread and the nipple surface. Friction between both spoke and nipple and rim and nipple are significantly reduced.
Coating also seals the surface reducing corrosion:
Silent, effective truing with no more squeaks
Virtually torsion free spokes
High tension wheels without problems
No over tight nipples on spoke threads
No more oily and dirty wheels
Just efficient dry working and clean hands
No unnecessary cleaning
Wheels are easier to true
