Sapim's original Polyax nipples have a rounded profile, which allows up to 9 degrees of adjustment for better spoke seating. Improved seating angle increases spoke life and overall wheel durability. These nipples are ideally suited for wheels with deep cross sections or tight spoke seats as they prevent problems arising from misalignment.
Most common material for nipples, brass nipples are generally nickel coated to ensure good corrosion resistance. Most wheel building robots can only work with brass nipples. Sapim offer brass nipples in silver and black.
