The Bianchi Oltre Comp 105 Di2 12sp serves as the high-performance "gateway" to Bianchi’s revolutionary Oltre "Aerovolution" lineup. While the flagship RC and Pro models are designed around the controversial Air Deflector technology (spoilers), the Comp uses a dedicated aero frameset that omits the deflectors to comply with a wider range of UCI regulations and offer a cleaner, more traditional look.
The Comp is arguably the most practical bike in the family; it features a semi-integrated two-piece aero cockpit (stem and bars) rather than the one-piece "Y" bar. This makes it significantly easier to adjust your fit or swap components while still maintaining the ultra-aggressive, wind-tunnel-tested silhouette of its siblings.

Key Technologies
Aerovolution Design: Although it lacks the Air Deflectors, the frame tubes are sculpted to "dominate the air" by smoothing flow over the wheels and reducing drag behind the seat tube.
Velomann Carbon V50R Wheels: This is a major value point for the Comp build. You get a true 50mm deep-section carbon wheelset stock, providing a significant mechanical advantage on flats and descents.
Two-Piece Aero Cockpit: Unlike the "Hyperbikes" (RC/Pro), the Comp uses a traditional (yet aero-optimized) stem and bar. This allows for easier stem-length changes and easier maintenance for home mechanics.
Shrouded Dropouts: Inspired by F1 aerodynamics, the fork and frame dropouts are integrated into the profile to reduce turbulent air at the axle interface.
Precision Electronic Shifting: The 105 Di2 system provides the same wireless shifting logic and speed as Ultegra and Dura-Ace, ensuring you never drop a chain during high-torque sprints.
