Specialissima Comp 105 Di2 / Celeste / 53cm

The Bianchi Specialissima Comp 105 Di2 represents the latest evolution of Bianchi’s legendary climbing flagship. For this generation, the Specialissima was completely redesigned to bridge the gap between a pure lightweight climber and a wind-cheating aero bike. While the Oltre series handles flat-out speed, the Specialissima Comp is the "all-rounder"—designed to be incredibly light for alpine ascents while adopting the aero-optimized head tube and integrated cockpit features from its more aggressive siblings.

The "Comp" tier is the entry point into this new generation of racing performance. It uses a high-modulus carbon layup that balances stiffness and weight perfectly for the enthusiast racer. This specific build is finished in the classic Celeste CK16 / Graphite Glossy, providing that unmistakable Italian aesthetic. With the Shimano 105 Di2 groupset, you get professional-level electronic shifting precision on a platform that is significantly more aerodynamic than its predecessors.

Key Technologies

• Aero-to-Weight Optimization: The new frame design features a slimmer, deeper profile than previous versions, significantly reducing drag on descents and flats without adding the weight typically associated with aero frames.

• 105 Di2 Electronic Shifting: Provides a semi-wireless cockpit that eliminates mechanical cable friction and ensures perfect gear changes even under high pedaling torque on steep climbs.

• Velomann Palladium Carbon Wheels: These 33mm mid-depth carbon wheels are designed to be lightweight enough for climbing while offering a noticeable aerodynamic benefit over standard alloy rims.

• Integrated Cockpit (AICR): By routing all cables internally through the stem and headset, the Specialissima Comp presents a clean front profile to the wind, saving valuable watts at higher speeds.

• Aggressive Racing Geometry: Despite being an "all-rounder," the geometry is pure race, with a short wheelbase and responsive handling designed for technical criteriums and high-speed cornering.
