Italian Performance. Endurance Refined.
The Basso Astra 105 Di2 is built for riders who want the speed and responsiveness of a performance road bike combined with the comfort and versatility required for long days in the saddle. Handcrafted in Italy and engineered around Basso's racing heritage, the Astra delivers a refined ride experience that feels equally at home on fast club rides, mountainous sportives and all-day adventures.
Constructed from high-modulus 3K Toray carbon fibre, the Astra balances lightweight performance with exceptional ride quality. Its endurance-focused geometry features a taller front end, slightly reduced reach and dropped seatstays to improve comfort without sacrificing the precise handling and efficiency that define every Basso.
The fully integrated Paradigma cable routing system creates a clean aesthetic while maintaining sharp steering performance, while generous tyre clearance of up to 35mm allows riders to tackle rough roads and mixed terrain with confidence. Paired with Shimano's proven 105 Di2 electronic groupset and Mavic Aksium wheels, the Astra delivers smooth shifting, dependable performance and outstanding value for performance-focused cyclists.
