The 2021 Specialized Tarmac S-Works SL6 Sagan Collection Deconstructivism is a World-Tour-proven aero-meets-climber road bike dressed in Peter Sagan's signature "Deconstructivism" black-and-green sparkle colorway. It pairs the Rider-First Engineered FACT 12r carbon chassis with a Shimano Ultegra Di2 12-speed drivetrain and Black Inc carbon wheels — a race-day build with unmistakable provenance.

Specialized is one of the most storied brands in cycling, founded in Morgan Hill, California in 1974 and responsible for innovations from the first mass-produced mountain bike to the Tarmac platform that has won more Grand Tours than any other bike in history. The Sagan Collection is Specialized's limited-run collaboration with three-time World Champion Peter Sagan, blending race-caliber engineering with graphics that have become instantly collectible.

This particular build centers on the SL6-generation Tarmac frameset, Rider-First Engineered so every size delivers the same precise ride feel, paired with a full S-Works FACT carbon fork, OSBB bottom bracket, and 12mm thru-axles front and rear. It has been upgraded to the latest Shimano Ultegra Di2 R8100 12-speed groupset with hydraulic disc brakes, a 52/36T semi-compact crankset in a 175 mm length, and full-system wireless shifting. The cockpit is a PRO Vibe Evo Aero one-piece carbon bar-and-stem in a 120 mm × 380/400 mm configuration for aggressive positioning, matched to an S-Works FACT carbon Tarmac seatpost with 20 mm offset. Rolling stock is a set of Black Inc Fifty C carbon wheels wrapped in supple Schwalbe Pro One 700x25c tires — a fast, light, aero package designed to go the distance. With Sagan-edition graphics, a flagship frame, and a modern 12-speed electronic drivetrain, this is a rare, ride-ready collector's build in size 58.
