Sapim Alloy Polyax SILS Black Nipples

Featuring the Sapim Integrated Locking System to prevent loosening.



Product details

Sapim Alloy SILS Black Nipples are a Polyax design, built with the Sapim Integrated Locking System. They are made from high-quality AL7075 T6 aluminium to be long-lasting, corrosion-resistant and lightweight, consistently out-performing lower grade alloy nipples.

High profile or radially mounted wheels are prone to impacts which can cause momentary loss of spoke tension, allowing nipples to loosen. SILS nipples have a special thread system which prevents loosening. A SILS nipple, which is self-locking, does not degrade over time, allowing wheels to be trued, re-tensioned, or re-dished with minimal hassle.

The rounded design of Polyax Nipples 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, creating a far superior fit.
