Description
- 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
