Zipp Sapim Double Square Nipples

The double square design allows you to adjust the spoke tension from both the top and the bottom of the nipple. This makes it significantly easier to true your wheels, especially when working with deep-section rims where access to the nipple head can be restricted.

You will need a specific double square spoke wrench to utilize the internal adjustment feature. While they can often be turned from the outside like a standard nipple, the internal square is the intended interface for precision building.

Each pack contains 34 nipples. This is typically enough to build a single wheel, though you should verify your specific spoke count before purchasing.

Aluminum is significantly lighter than brass, which helps reduce rotational weight at the rim. While brass is generally more durable against corrosion, these aluminum nipples are a great choice for performance-focused builds where every gram counts.

The 16mm length is a standard size, but compatibility depends on your rim's spoke hole diameter and the length of your spokes. Always measure your current setup or consult your rim manufacturer's specifications to ensure you have the correct spoke length to match these nipples.
