Sapim Polyax Alloy Nipples

  • Overview...
  • Designed and manufactured in Wilrijk, Belgium
  • Developed in 1995 and sold through 2019
  • Designed to produce a better spoke-nipple line - prolonging the life of the nipples, as well as the rim
  • Sapim's Polyax head shape allows for better nipple orientation at the rim, reducing stress at the spoke threads and increasing spoke fatigue life
  • The round shape of the head works like a ball-joint between the rim and nipple
  • Rounded profile allows up to 12 degrees of adjustment for better spoke seating
  • The manufacturing process on a unique CNC machine guarantees extraordinary coaxialit
  • Made out of high quality aluminum - the material of choice (over brass) for higher performance wheel nipples
  • Combines light weight, strength, and corrosion resistance
  • Roughly three times lighter than Sapim Polyax brass nipples
  • Being made out of aluminum, these are significantly weaker than brass nipples, but still preferred by BMX racers and many top park riders
  • Sapim's aluminum nipples have become the benchmark in the market - their state of the art manufacturing process ensures the best quality available
  • Given double surface treatments - a bright anodized finish and a corrosion-reducing coating that also reduces friction  at the threads and rim interface
  • The anodized surface treatment provides several vibrant color options
  • All Sapim Polyax aluminum nipples have undergone a surface treatment that allows for wheel mounting without a lubricant
  • Nipple threads and heads are coated to significantly reduce friction between both spoke and nipple and rim and nipple - a unique process developed by Sapim that is now now standard in Sapim's production
  • Available in three sizes - longer nipples to accommodate rims with deeper profiles
  • Note that the extra length of the longer nipples is effectively an unthreaded extension down the spoke - if you're looking to correct for short spokes, this is not a fix
  • The threads of the 14mm and 16mm long nipples are not longer and are in the same location as the 12mm long version with respect to the nipple head
  • Coating Advantages...
  • Silent, effective truing with no more squeaks
  • Virtually torsion free spokes
  • High tension wheels without problems
  • No over tight nipples on spoke threads
  • No more oily and dirty wheels
  • Just efficient dry working and clean hands
  • No unnecessary cleaning
  • Wheels that are easier to true
  • Details...
  • Purpose: to provide the connection between the rim and spoke
  • Material: 7075 T6 alumunum - the highest aluminum grade possible for this sort of usage
  • Forming process: CNC machined
  • Drilling process: drilled by high precision machinery - to ensure meticulousness and quality
  • Surface treatment: anodized - done by carefully chosen partners of Sapim
  • Coating: a unique process developed by Sapim to reduce friction on alloy nipples
  • Colors: silver, black, red, orange, gold, blue, green, purple
  • Manufacturers part number (MPN): 14GR3AB (14g, black); 14GR3A (14g, silver);
  • Specs...
  • Size: 2mm (14g) - for 14 gauge spokes
  • Threads: 2.2 mm x 56tpi
  • Length: 12mm, 14mm, 16mm - note that you can't compensate shorter spokes with longer nipples because all three sizes have the same length of internal threads
  • Weight (each): 0.3016g (12mm), 0.3409g (14mm), 0.3875g (16mm)
  • Other...
  • Sold in bags of 100 nipples
