Sapim Double Square Polyax Spoke Nipple

Anodized aluminium nipples save weight and are an eye-catcher for every wheel. Sapim's anodized Polyax nipples are treated with a special coating to increase durability and allow for easier wheel building. The 16 mm nipples have a 2 mm thread for rims with Ø 3.5 mm holes.

Double Square nipples were developed for special centering machines. This nipple form is becoming more and more popular because the visible surface of the tightening areas does not get damaged. Double Square nipples get tightened from the inner side of the rim.

These Polyax nipples include Sapim's "SecureLock" feature which prevents the spoke nipple from loosening under stress / destress situations.
