specialissima comp 105 di2

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.
