Interloc Double Roller Drive Headset.


  • Roller bearings for both the upper and lower cups for improved headset performance
  • Roller bearings offer 3 distinct areas of advantage over traditional round bearing headsets: steering dampening, greater strength, and greater durability
  • Increased bearing contact acts as a damper absorbing high and low speed vibrations
  • Roller bearings have a much greater contact area offering increased strength
  • Load is spread over a great area with roller bearing, reducing pitting and race wear, dramatically increasing durability
  • Precision CNC-machined 7075 aluminum cups
  • 1" option uses a 26.4mm crown race
