Sapim Polyax Brass Nipples




Sapim Polyax Brass Nipples

  • Overview...
  • Designed and manufactured in Wilrijk, Belgium
  • Developed in 1995 and sold through 2019
  • Made out of high quality brass - the most common material for wheel nipples
  • Designed to produce a better spoke-nipple line - 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
  • Roughly three times heavier than Sapim Polyax aluminum nipples
  • Being made out of brass, these are significantly stronger than aluminum nipples
  • For use in a corrosive environment or extreme use
  • 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
