Specialized Tarmac SL6 (custom build) - 2021, 58 cm

Specialized Tarmac SL6 (Custom Build), Size 58 — a top-tier carbon road bike built for pure performance, efficiency, and race-level feel. This custom SL6 comes in at an impressive 16.5 lb, making it exceptionally light and responsive, ideal for riders approximately 5’11”–6’2”. The frame is paired with a premium Shimano Dura-Ace Di2 2x11 drivetrain, featuring a 52/36 crankset and 11–34 cassette, delivering crisp electronic shifting with a wide enough range for both fast flats and demanding climbs. An Ultegra RX Di2 rear derailleur adds extra chain stability, especially on rougher roads. Stopping power is handled by a mix of Shimano Dura-Ace / Ultegra brakes, providing excellent modulation and confidence at high speeds. The bike rolls on Roval C38 carbon wheels with DT Swiss 350 hubs, set up tubeless with Continental GP 5000 TR 28C tires, offering an outstanding balance of speed, comfort, and reliability. Finishing touches include a Specialized S-Works carbon seatpost, Zipp 120mm stem, Zipp 420mm handlebars, and a Specialized Power saddle, rounding out a clean, high-end build. This bike is pre-owned and in good condition, with only minor cosmetic marks consistent with normal use, and is fully ready to ride.

Why we love it

We love this Tarmac SL6 because it represents the perfect blend of low weight, stiffness, and refined road feel. The Dura-Ace Di2 drivetrain delivers flawless shifting every time, while the Roval carbon wheels and GP5000 tires make the bike feel fast and smooth on any road. It’s a true rider’s bike — light, sharp, and confidence-inspiring — built for someone who values performance above all else.
