Description
Specialized Tarmac SL9 Expert Ultegra Di2 Road Bike
Engineered to convert every ounce of effort into blistering real-world speed, the Specialized Tarmac SL9 Expert Ultegra Di2 Road Bike represents the benchmark for modern road racing performance. Built around an advanced FACT 10r carbon frame that is both Rider-First Engineered and wind-tunnel optimized, this race machine strikes the perfect compromise between lightweight agility and aerodynamic efficiency. Weighing in at just 7.53 kilograms, it provides exceptional responsiveness on steep ascents and supreme stability on rapid descents, ensuring ambitious riders achieve their fastest possible time to finish.
Electronic Shifting and Precision Components
Power transfer and gear management are handled seamlessly by the world-class Shimano Ultegra Di2 12-speed electronic drivetrain, delivering lightning-fast, precise shifts at the touch of a button. Paired with reliable Ultegra hydraulic disc brakes, riders gain absolute control and stopping confidence across all weather conditions and terrain profiles. The bike rolls on lightweight Roval C38 carbon tubeless-ready wheels wrapped in high-performance S-Works Turbo tyres, offering lower rolling resistance, fantastic cornering traction, and an ultra-smooth ride quality.
Race Ergonomics and Practical Design
Designed for both competitive racers and dedicated enthusiasts, the cockpit pairs an aerodynamic Roval Rapide alloy stem with Specialized Expert shallow drop handlebars for comfortable hand positioning during long efforts. The setup is anchored by a Body Geometry Power Expert saddle with hollow titanium rails and an S-Works carbon seatpost to damp road vibrations and reduce fatigue over long distances. Combining elite race heritage with durable, high-value components, this complete package provides third-party buyers with an irresistible upgrade ready to dominate local races, sportive events, and fast group rides.
