- High performance - OCLV Carbon frame. Race-optimised cable routing. World Champion Fabian Cancellara's seal of race-ready approval. Performance doesn't get any higher than this.
- Stable - Balanced, race-stable geometry and integrated chain keeper give Domane extraordinary handling and flawless gear shifting on any road, under any load. This bike will not let you down.
