Sapim SILS Polyax Aluminum 14mm Nipples

High profile or radially mounted wheels are prone to impacts which can cause momentary loss of spoke tension, allowing nipples to loosen. Sapim SILS Polyax Aluminum nipples (Sapim Integrated Locking System) 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 14 mm Sapim SILS nipples are equipped with a hex head, making them ideal for use with aero bladed spokes. Tightening the nipple from the external side of the wheel allows the spoke blade to be held as close as possible to the nipple, preventing spoke twist.

Aluminum nipples have about one-third the mass of a brass spoke nipple and save on the overall weight of a wheelset. However, alloy nipples are not recommended in wet or salty riding conditions due to corrosion potential.
