Step 1: Select Rim
Current stock: 0

Sapim's original Polyax aluminum nipples have a rounded profile, which allows up to 9 degrees of rotation for improved spoke alignment and durability. 

Aluminum nipples have about one-third the mass of a brass nipple for weight savings at the rim/spoke interface.

Wheelbuilder does not recommend using alloy nipples in wet or salty environments due to their limited corrosion resistance.
