Double Roller Drive Headset, 1" Threaded

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
