Specialized S-Works Tarmac SL8 - Dura-Ace Di2 – Fulcrum Speed 42

We took the fastest racing frame in the world, the Specialized S-Works Tarmac SL8 in the exclusive color Gloss Solidity / Red To Black Pearl / Metallic White Silver (SLDMET/REDPRL/METWHTSIL) and transformed it into a project custom build by Cicli Drigani.

This setup features the Shimano Dura-Ace Di2 12v with Powermeter groupset, offering ultra-fast wireless electronic shifting and the ability to monitor watts, cadence, and balance in real time.

• Full carbon rim with Front profile 51 mm / rear 48 mm.

• 21 mm internal channel for perfect integration with 28 mm tires, improving comfort and smoothness.

• Tubeless ready for maximum efficiency and puncture reduction.

• USB™ ceramic bearings for superior smoothness and reduced maintenance.

• Competitive weight of only 1,305 g for the pair, making the bike agile on climbs and very fast on accelerations.

The Roval Rapide cockpit and the saddle S-Works Power complete a ready to race bike, capable of offering the ideal mix of aerodynamics, lightness, and comfort for high-level races and training.

Each Custom Tarmac SL8 is hand-assembled by Cicli Drigani technicians, with obsessive attention to detail.
