If you're searching for a high-performance used road bike, the Specialized S-Works Tarmac SL6 Custom Build delivers an exceptional combination of race-proven performance, premium components and outstanding value. Built around the lightweight FACT 12r Carbon S-Works Tarmac SL6 frame, this 54cm machine offers the stiffness, responsiveness and agile handling that have made the Tarmac a favourite among serious road cyclists. The 2019 frame is paired with a carbon Tarmac fork and CeramicSpeed OSBB bearings, creating a refined, race-focused platform that's equally suited to fast training rides, sportives and competitive racing.
The impressive custom specification continues with Shimano Dura-Ace R9150 Di2 11-speed, providing fast, precise electronic shifting alongside powerful Dura-Ace hydraulic disc brakes. A 52/36T Dura-Ace crankset and 11-30T Ultegra cassette provide an excellent balance of speed and climbing versatility, while the Light Bicycle 36mm carbon wheels with Carbon-Ti hubs help keep weight down and acceleration sharp.
Continental Grand Prix 5000 S TR 28c tyres, a Pro Vibe Carbon Aero handlebar and S-Works Power Pro Elaston saddle complete a premium build that represents a compelling opportunity to own a genuine S-Works Tarmac with a high-end specification at an accessible price.

Founded in California in 1974, Specialized began with a simple promise: serious riders deserve serious gear. Half a century later, the brand still funds its own wind tunnel, builds its own carbon, and tests every bike with the world's best so that you ride your own best.
The first production mountain bike. The first cycling-specific shoes. FACT carbon, the Win Tunnel, S-Works. Specialized has a habit of building the things the rest of cycling ends up copying.
