Specialissima Pro Shimano Ultegra Di2 12sp

The Specialissima lineup splits into three distinct tiers: RC, Pro, and Comp. The flagship RC (Reparto Corse) models use the lightest high-modulus carbon layup and minimal paint to achieve the lowest possible weight. These premium builds feature the integrated Reparto Corse cockpit, deep carbon wheels with ceramic bearings, and top-tier electronic groupsets from Shimano, SRAM, and Campagnolo, often including power meters.

The mid-range Pro tier is widely considered the sweet spot for value and ride quality. While the frame adds a marginal amount of weight over the RC, it integrates Bianchi’s Countervail vibration-damping technology and features more elaborate paint schemes. Pro builds retain the integrated carbon cockpit and roll on 33mm Velomann Palladium carbon wheels, paired with Ultegra or Force groupsets.

The entry-level Comp tier uses a standard carbon layup without Countervail and switches to a two-piece Velomann alloy bar and stem, though the frame remains compatible with the integrated cockpit. Comp models are equipped with 105, Rival, or Ultegra electronic groupsets and share the same 33mm Velomann carbon wheels as the Pro, offering the core Specialissima handling at a more accessible price point.

Reviewers consistently praise the Specialissima for its immediate acceleration and climbing prowess. The frame’s high torsional stiffness translates power efficiently, making it "bonkers light, crazy fast, and just silly fast on basically any road" (Cycling News). On descents, the bike maintains composure rather than feeling nervous, with one tester noting it "feels calm with purposeful, not jittery steering" (YouTube).

While the chassis itself is highly regarded, the stock tire specification on the top-tier RC models drew widespread criticism. The factory-fitted 26mm Pirelli TT tires prioritize straight-line speed over grip and puncture protection, leading multiple reviewers to note they "struggle in the corners" (Cycling News) on wet or broken pavement. Swapping to wider, tubeless-ready rubber is universally recommended to improve both traction and ride quality.

Ride comfort varies significantly by frame tier. The Pro model, which features Bianchi’s Countervail technology, is lauded for its ability to mute road chatter. Reviewers found that this viscoelastic material effectively "turns vibrations into thuds" (Velo), allowing the bike to remain stiff under power without punishing the rider over long distances. The RC model, lacking this damping layer, delivers a firmer, more uncompromising race feel.
