14g Sapim Double Square Black Brass 16mm(12mm) Secure-Lock Polyax.

14gauge Sapim Double Square Black Brass 16mm(12mm) or 18mm(14mm) Secure-Lock Polyax nipples.

Spoke wrench:(3.2mm) PT SW-16, DT Swiss Proline RED T-handle for hidden square nipples. Can be tightened from the outside and the inside.

 

Material: Brass

Colour: Black

 

Length: 16mm, 18mm

4 mm of the total length must be removed to compare this nipple's length to other nipples. Because a Double Square nipple extends further inside the rim. So an 18mm Double Square nipple is a 14mm and a 16mm Double Square nipple is a 12mm.

 

This nipple won't fit shallow rims like the H+Son TB14 rim. If you want a nipple that can be tightened from inside of the rim, use a hex head nipple.  Available in brass silver or brass black.

Perfect for a black TB14 rim. A black rim with black brass nipples, black spokes and a black hub. You can't beat it!

 

Polyax Nipples

The rounded design of the Patented Polyax nipple head reduces the stresses produced by axial and lateral forces (inherent in wheels with low spoke counts and crossings). Polyax nipples re-align themselves within a rim hole up to 9 degrees in a radial direction and 6 deg in an axial direction, making for a much superior fit.

 

Secure-Lock

The patented Secure Lock nipple of Sapim is a locking mechanism that prevents nipples from untightening.

 

Easy to recognize SAPIM INTEGRATED LOCKING SYSTEM Highly precise and accurate punching machines are needed to form this type of locking system in order to achieve a stable and well defined deformation on the thread. Each nipple has an additional locking resistance of 18 +/- 3 cNm.

 

No need to add spoke freeze, spoke fix, spoke prep, spoke lock or Locktite 222, Locktite 243, Locktite 290 or Locktite 638.
