- 180 degree faceplate design distributes clamping forces evenly over a larger area
- Unique integrated bolt thread design is lighter and stronger than traditional designs
- Carbon-friendly steerer clamp helps spread out clamping load on lightweight steerers
- 4-bolt handlebar clamp holds bar securely and evenly distributes forces over a wider area
