Official sizing guide for 2026
As the world's oldest bicycle manufacturer, Bianchi uses traditional Italian numeric sizing measured in centimeters along the seat tube. Their Countervail vibration-dampening technology is integrated into the carbon layup across all sizes, and each frame is designed to preserve the classic Italian racing geometry that has defined professional road cycling for over a century.

Specific sizing recommendations for Bianchi's most popular bike models. Geometry measurements shown for reference size (typically M or 54cm).
Aero race bike with Countervail technology and fully integrated cable routing. The aggressive aero position has a lower stack than the Specialissima—riders prioritizing comfort should consider the next size up.
Lightweight climbing bike weighing under 6.8 kg. Balanced race geometry offers a slightly more relaxed position than the Oltre, making it well-suited for gran fondos and mountain stages.
Endurance road bike designed for all-day comfort with Countervail vibration dampening. Taller head tube and shorter top tube create a more upright position—most riders fit their standard road size.
High-performance alloy road bike offering race-level geometry at a lower price point. Hydroformed aluminum frame runs true to Bianchi's standard numeric sizing—ideal for riders entering competitive cycling.
Carbon gravel bike with Countervail technology for off-road vibration dampening. Slightly longer wheelbase and higher bottom bracket than road models—size the same as your Bianchi road bike for consistent fit.
