Basso Astra 105 Di2 Road Bike, Cosmic S, Cobalt Grey

Handmade Italian Carbon Performance, Refined for Every Road

At Aztecs Bikes, we selected the Basso Astra 105 Di2 because it represents the finest Italian carbon engineering at a competitive price point. Handmade in Possagno, Italy since 1977, Basso was among the first brands to pioneer carbon fibre frame construction. The Astra combines a UCI-approved 3K Toray carbon frame weighing just 980g with Shimano 105 Di2 electronic shifting, creating a road bike that blurs the line between racing machine and all-road explorer. Paired here with Mavic Cosmic S wheels, it is a seriously capable platform for riders across East London and the UK.

Why We Chose This for Our Customers:

• UCI-Approved 3K Carbon Frame: Handmade in Italy at just 980g, offering race-level stiffness with 35mm tyre clearance for all-road versatility.
• Shimano 105 Di2 Electronic Shifting: Precise, wireless gear changes with a 12-speed cassette for smooth performance in all conditions.
• Paradigma Integration System: Fully integrated cable routing that preserves light steering feel, with a cable-free stem for easy maintenance.
• Mavic Cosmic S Wheelset: Performance disc wheels with UST tubeless-ready rims for speed, reliability and reduced puncture risk.
