About the S-Works Aethos

Float Through The Hills

• Ultralight climber with brilliant handling
• Responsive and comfy geometry across terrains
• Carbon layup creates a bike so light it breaks UCI rules
• Perfect balance of front and rear stiffness
• Aerodynamics discarded in favor of outstanding ride quality
• S-Works boasts the pinnacle of frame technology and comes standard with elite components

The S-Works Aethos is the best build of this comfy, telepathically responsive road bike. Rideability feels like a buzzword, but the Aethos delivers. There was no wind tunnel testing and it's not even UCI-legal, so if breaking the rules for a great ride is your vibe, enter Aethos.

Highlights
- This bike combines ultralight carbon with sublime handling.
- Tuned front & rear brakes, firming up lever pull & creating consistent grab.

Master Mechanic's Notes:
- This bike is in excellent condition.
