Infinito Shimano 105 12sp

The 2024-on Bianchi Infinito is a modernization of the brand’s non-Countervail endurance road platform rather than a wholesale redesign. Its defining update is cabling integration: the top build routes hoses and cables fully through the bar and stem and into the frame via the upper headset bearing, while lower-spec versions use a semi-external arrangement that still enters the frame around the headset. That brings the bike in line with current road-bike packaging trends, but the underlying brief remains familiar: a practical endurance road bike for long rides, all-day comfort, and general road use rather than outright race-bike sharpness.

Bianchi also shifted the fit slightly toward accessibility by increasing stack with a taller head tube, reinforcing the Infinito’s role as the more approachable option beneath the Infinito CV. Tyre clearance stays at 32mm, which is competitive for an all-road-leaning endurance bike without pushing into gravel territory, and the frame continues to use a BB86 press-fit bottom bracket. Overall, this generation sits as Bianchi’s everyday endurance road model: cleaner-looking and more contemporary in its front-end design, but still centered on stable handling, comfort, and a less aggressive riding position.

Fit and geometry

The geometry supports the Infinito’s endurance brief clearly. Stack ranges from 521mm in the 47cm size to 614mm in the 61cm, while reach stays relatively restrained at 371-392mm across the size run. That combination points to a taller, shorter front end than a typical race bike, making it easier for riders to achieve a comfortable bar height without an extreme spacer stack. Bianchi’s emphasis on the taller head tube is reflected in the numbers and should suit riders prioritizing long-hours comfort over an aggressive, low cockpit.

Handling figures also favor stability. Head tube angles run from 70.5 to 72.5 degrees depending on size, paired with 415mm chainstays on most sizes and 420mm on the two largest frames. Wheelbase grows from 986mm to 1023mm, again consistent with a planted endurance-road feel rather than quick, nervous steering. The 68mm bottom bracket drop is moderate and conventional for this category. Taken together, the geometry suggests predictable road manners, steady tracking on longer rides, and fit that will be more accommodating for a broad range of riders than Bianchi’s racier models.

Builds

The Infinito range is offered in four builds: Shimano Ultegra Di2 12-speed, Shimano 105 12-speed, and two Shimano 105 Di2 listings. Even without detailed component breakdowns or pricing, the lineup structure is clear. The Ultegra Di2 model serves as the premium option, pairing the most integrated cockpit execution with a higher-end electronic drivetrain, while the mechanical 105 12-speed build is the most straightforward entry point into the platform.

The two 105 Di2 builds indicate that Bianchi is placing particular emphasis on mid-range electronic shifting for this generation, which fits the bike’s modernized positioning. In practical terms, buyers are choosing between a simpler, likely lower-cost mechanical setup, the value-oriented appeal of 105 Di2, and the lighter, more upscale Ultegra Di2 flagship. Across the range, the key distinction is not just drivetrain tier but also cockpit integration, with the top model getting the cleanest fully internal routing solution.
