The Bianchi Sprint 105 Disc 12sp represents the major update to Bianchi’s iconic entry-level carbon racer. The transition from the "YS" (11-speed) to the "YT" (12-speed) model code signals more than just an extra sprocket; it marks the frame's evolution toward a much cleaner, more aerodynamic aesthetic. This version adopts Internal Cable Routing (ICR), moving the housings away from the wind and into the headset, giving the bike a silhouette that closely mimics its high-end WorldTour counterparts.
Built with the Shimano 105 R7100 12-speed mechanical groupset, this bike is the ultimate choice for the "mechanical purist" who wants the wide gear range of a modern 12-speed system without the need for battery management. It remains a sharp-handling, reactive race bike that excels in criteriums and fast group rides, finished in the legendary Celeste CK16 Glossy.

Key Technologies
12-Speed Mechanical Precision: The R7100 groupset provides a 1:1 gear ratio (34T front / 34T rear), making the Sprint significantly more capable on steep alpine climbs than the previous 11-speed version.
Internal Cable Routing (ICR): By routing the cables through the stem and headset, Bianchi has eliminated the "cable nest" in front of the headtube, reducing drag and protecting the housings from the elements.
Carbon Monocoque Construction: The frame is designed with a high stiffness-to-weight ratio, ensuring that high-wattage efforts—like sprinting for a finish line—result in immediate acceleration.
Refined Geometry: The Sprint maintains an aggressive "racing" posture with a short headtube, allowing riders to achieve a low, aerodynamic tuck.
V30R Aero Wheels: The 30mm rim depth offers a versatile balance; it’s shallow enough to be stable in crosswinds but deep enough to offer a slight aerodynamic advantage over traditional box-section rims.
