A special coating is a new way to reduce friction at aluminum nipples.
The coating is applied to the thread and the nipple.
In this way, we reduce the gratings on the spoke-nipple and rim-nipple lines.
The coating also increases corrosion resistance.
Sapim has patented the Polyax nipples.
Because of their special structure, they help to adjust the nipple to the rim.
This solves the problem of a spoke breaking at the nipple.
As a result, the spokes fit better into the wheel.
