Basso Astra Frameset

The Astra frameset accommodates tires up to 35 mm wide. This clearance provides enough versatility to run slightly wider, more comfortable tires for rougher road surfaces without sacrificing its racing geometry.

Yes, the Astra is designed with 'Double Fit' technology, making it fully compatible with both mechanical and electronic groupsets. You can build it up with your preferred drivetrain, whether it is Shimano 105 Di2, Ultegra Di2, SRAM Rival AXS, or a mechanical system.

Absolutely. The Astra is UCI approved, meaning it meets the strict standards required for professional and competitive road racing. Its design prioritizes stiffness and aerodynamics, making it a capable machine for high-intensity riding.

The internal cable routing is designed for a clean aesthetic and improved aerodynamics, but it does require a bit more patience during assembly and maintenance. It is a standard setup for modern high-end road bikes, so any experienced mechanic will be familiar with the process.

The frame weighs 980 grams. This lightweight construction is achieved through Basso's specific carbon fiber layup, which balances stiffness for power transfer with the durability needed for long-distance performance.

The Astra supports seatpost setups with either a -15 mm or 0 mm setback, allowing you to fine-tune your position for optimal comfort and pedaling efficiency.
