2017 Cervelo S3 Disc Ultegra Di2 6870 56

Features: 

- BBright: This asymmetrical 79mm bottom bracket standard yields stiffer and lighter frames and crank systems
- Carbon dropouts: Tough, compression molded dropouts save weight with no sacrifice in strength compared to traditional metal dropouts
- Future-proof cable management: Ensures your frame is compatible with all current and future derailleur and brake systems
- Partial seat tube cutout: A close-fitting curve in the seat tube's trailing edge improves aerodynamics by partially shielding the leading edge and top of the rear wheel
- Reduced-friction BB guide: Significantly reduces cable friction in the bottom bracket, which means smoother shifting, easier setup and longer service intervals

The S3 Disc is stiffer and more aerodynamic than its rim-brake counterpart, while continuing to make the most of the lightweight design rooted in Cervelo's Project California research facility. All of this translates to superior handling and control, giving you the confidence to pull away from the peloton or put the hurt on a Saturday morning group ride. Built on an ultra-lightweight Cervelo carbon frame, the S3 Disc features effortless Shimano Ultegra Di2 electronic shifting, FSA SLK crankset for efficient power transfer, powerful Shimano hydraulic disc brakes, high-quality ENVE SES 3.4 wheelset, and a supportive Fizik Antares saddle. Stiffer, better-riding, aero as ever. All with zero weight penalty.
