The Sapim 14G Polyax Brass Double Square Black Spoke Nipple is a strong, low-maintenance nipple for high-quality wheel building, ideal for MTB, gravel and trekking wheels.

 Product specifications

 
 Made of brass for maximum strength, corrosion resistance and long life, with a black finish for a sleek look.
 
 Suitable for 14G spokes (2.0 mm thread), Polyax head with semi-circular contact surface for optimal alignment between spoke, nipple and rim.
 
 Double Square design with an additional square on the inside of the rim, typically 16 or 18 mm in length, comparable to standard 12 and 14 mm Polyax nipples respectively.


 Benefits for wheel builders

 
 Double Square allows centering from the rim bed side, preventing damage to the visible part of the nipple and keeping sensitive rims scratch-free.
 
 Polyax “ball joint” head reduces tension peaks on the spoke thread and helps prevent spoke breakage at the nipple winding.
 
 Brass construction combined with Secure Lock option delivers highly reliable tension, even under intensive use and heavy braking or e-bike loads.
