Sapim Polyax aluminum inner (inverted) 15G nipples
Sapim Polyax aluminum inner (inverted) nipples retain an ideal line for spokes, prolonging their life as well as that of the rim.
The new manufacturing process on a specific CNC machine guarantees extraordinary coaxiality. The Sapim Polyax nipples are made of 7075 T6 aluminum alloy, which makes it possible to put a lot of stress on the nipple (also available in brass for use in a corrosive environment or extreme use).
All internal Sapim Polyax aluminum nipples have undergone a specific surface treatment that allows wheel mounting without lubricant.
10mm Alu 15G (1.8mm).
