NEW 2027 Bianchi Specialissima - Shimano 105 Di2

Bianchi Specialissima / 2027 / Shimano 105 Di2 A race bike that loves the mountains. The Specialissima has always been a climber's bike. The latest generation adds a more aerodynamic shape and a cleaner integrated front end, without losing the lively, direct feel that makes a steep road worth seeking out. This 2027 Shimano 105 Di2 build has a particularly smart specification: an integrated Reparto Corse carbon cockpit, 49 mm Bianchi carbon wheels, 30 mm Continental tires and, crucially, a 50/34T crankset paired with an 11–36T cassette. You get the speed of a modern race bike with genuinely useful gearing for long and difficult climbs. Climbing cassette 11–36T Wide 12-speed range for sustained gradients Compact chainrings 50/34T A practical choice for mountain roads Electronic shifting 105 Di2 Shimano 12-speed precision Carbon wheels 49 mm Bianchi B 49R, tubeless-ready Gearing that makes sense in the mountains A 36-tooth climbing gear changes the conversation. On the steepest sections, this bike's 34T inner chainring and 36T largest rear sprocket give you a gear that's a little lower than 1:1. That means more room to keep pedaling smoothly when the grade bites or when a long ascent begins to take its toll. The 50T outer chainring still feels at home on fast flats and descents. It's a balanced setup for riders who want a performance road bike without saving their easiest gear for emergencies. The ride Made for more than the summit. 01 Shimano 105 Di2 Reliable 12-speed electronic shifts with hydraulic disc braking. The standout is the 11–36T cassette: paired to compact 50/34T gearing, it offers a welcome low gear for steep climbs, tired legs and long days in the hills. 02 The Specialissima carbon platform The Specialissima PRO-carbon frame construction and Countervail-equipped fork give this build the fit and purpose of Bianchi's race platform. Internally routed cables, an integrated carbon cockpit and aero seatpost keep the silhouette clean and the handling direct. 03 Bianchi B 49R carbon wheels The 49 mm rims bring useful aero depth to a bike with climbing at its heart. A modern 25 mm internal rim width works with the fitted 30 mm Continental Grand Prix TR tires; the wheels are tubeless-ready if you prefer that setup. 04 The classic Celeste, reconsidered The JE Metallic Celeste / Dark Celeste finish has more depth than a single-color paint job. CK16 graphics and full-gloss clearcoat finish the look. This listing is offered only in that color, in 55 and 57 cm. Choose your fit 55 cm or 57 cm. Both sizes use Bianchi's 110 mm / 400 mm integrated carbon cockpit. The 55 cm is specified with 170 mm cranks, while the 57 cm uses 172.5 mm cranks. Their fit differs in stack and reach, so talk to us if you're between the two before making the call.
