NEW 2027 Bianchi Specialissima Pro Ultegra Di2

Bianchi • Reparto Corse • Model Year 2027 Every climb is a beginning. Not a finish line. The 2027 Bianchi Specialissima Pro Ultegra Di2 is designed for the rider who refuses to choose between a responsive climbing bike and an aerodynamic race machine. Built around Bianchi's latest Specialissima Pro carbon platform, it pairs electronic Shimano Ultegra Di2 shifting, a factory-integrated 4iiii Precision 3 power meter, and RC 49R carbon wheels in one cohesive, race-focused package. Exclusive color offered in this listing: JB — Petrolio / Metallic Celeste with CK16 graphics, the distinctive satin-and-gloss two-tone finish. RACE-READY CHASSIS Specialissima Pro carbon with fully internal routing, UDH compatibility and Bianchi Countervail vibration damping. PRECISION POWER Shimano Ultegra Di2 2×12 with a factory-fitted 4iiii Precision 3 left-side power meter. DEEP-SECTION SPEED Bianchi Reparto Corse RC 49R 49 mm carbon wheels, tubeless ready, paired with Continental GP 5000 S TR 30 mm tires. ONE BIKE. EVERY TERRAIN. A purposeful balance of climbing response, high-speed efficiency and confident descending. The new Specialissima Light on the ascent. Unrelenting on the flats. Bianchi reports a 16-watt aerodynamic improvement at 50 km/h versus the prior-generation Specialissima. That is a manufacturer comparison, not a guarantee of individual speed savings. The point is the engineering: refined airflow at the front end, optimized carbon shapes and a tightly integrated cockpit without abandoning the responsive character riders expect from the Specialissima. Precision from pedal stroke to pavement Ultegra Di2 R8150/R8170 delivers crisp, repeatable 12-speed electronic shifting. Bianchi's standard 52/36T chainrings and 11–34T cassette create gearing for fast group rides, rolling races and demanding gradients. The integrated left-side 4iiii power meter turns training data into something you can use from the first ride, without a separate crank upgrade. The 49 mm-deep RC 49R carbon wheels pair an aero-focused rim with a modern 25 mm internal width. Continental GP 5000 S TR 30 mm tires add a fast, sure-footed connection to the road. Disc braking, a full-carbon aero seatpost and the Reparto Corse integrated carbon cockpit complete the build.

This Pro Ultegra Di2 build adds the factory 4iiii Precision 3 power meter and Bianchi RC 49R carbon wheelset. Check the exact build specifications when comparing models; the standard Specialissima Ultegra Di2 is a different product. Is the power meter dual-sided? No. Bianchi specifies a 4iiii Precision 3 single-sided power meter integrated with the Shimano Ultegra crankset. Are the wheels tubeless ready? Yes. Bianchi lists RC 49R carbon wheels as tubeless ready and Continental Grand Prix 5000 S TR 30 mm tires. Confirm the delivered tire setup and sealant with our mechanics before riding tubeless. What is the gearing? Shimano Ultegra Di2 2×12 with 52/36T chainrings and an 11–34T cassette. How much does the complete bike weigh? Bianchi has not published a verified complete-bike weight for this exact 2027 Ultegra Di2 build. Reported Pro-frame weights are not complete-bike weights; contact Brimstone for build-specific weight information. Can I choose my cockpit size or confirm my fit? Contact Brimstone before ordering. Integrated carbon cockpits use size-specific dimensions; availability of alternative lengths or widths depends on Bianchi and the order configuration. Is this the exact JB paint finish? Yes: JB Petrolio Celeste / Metallic Celeste with CK16 graphics. Bianchi describes this finish as a combination of satin and gloss surfaces. Retailers may shorten the name to JB Metallic Celeste / CK16 Glossy. Does Brimstone ship this bicycle? Yes. Contact Brimstone for availability and delivery arrangements.
