Polyax Nipples

The rounded design of the Patented Polyax nipple head reduces the stresses produced by axial and lateral forces (inherent in wheels with low spoke counts and crossings). Polyax nipples re-align themselves within a rim hole up to 9 degrees in a radial direction and 6 deg in an axial direction, making for a much superior fit.
