  • Hydro Disc Brakes

The 2021 Astra pushes the limits farther than any version before it and does so with a good dose of style. Produced entirely in house by the skilled hands of the Basso staff, the latest version of the Astra model incorporates a great deal of technology that derives from its upper tier siblings and adopts a design that follows a tighter family feeling than ever before.

True to its Basso DNA the Astra is a thoroughbred racehorse ready to take you further, faster and with more confidence. The straight fork and rear triangle take design cues from their higher tier brethren on the SV and as such incorporate a similar reactive and responsive handling. Basso developed geometry studied to confer the perfect blend of snappy handling and acceleration and a comfortable position for the long haul.

Italian style at its best. The addition of an integrated seat post clamp, internal cable routing, and the most elegant stem in the cycling world create a frame that turns heads in terms of performance and elegance.

Made by hand, in Italy. Constructed from 100% 3k Torayca High Modulous Carbon Fiber from a blend of T700 and MR60 fibers, the Astra is capable of offering performance on par with its higher tier siblings with the only compromise coming in the form of a few extra grams. Constructed by hand, in house, the Astra, just as the rest of Basso frames, are made to be as beautiful inside as out.

Basso Technology

  • Windshape: Shaped to make you faster. Each and every tube in the construction of the Diamante SV has been made to reduce aerodynamic drag to a minimum, thus allowing you the rider to move forward faster and with less effort. Our aerodynamic approach seeks to develop a versatile design that takes into account the highly variable wind situations and angles that the rider may find themselves in. Aero optimized not for the wind tunnel but rather for the real world.

  • Carbon Fibre Frame Technology: Basso was among the first to research, develop and employ carbon in its frames. By not only building with carbon but researching new methods and techniques to continually improve performance, reliability and durability the Basso frame is an advanced piece of technology that rivals anything else on the market and rides like only a Basso can. The beauty of such technology is that the fantastic ride quality that derives from such engineering is permanent, making the Basso frame perform equally after several seasons’ use as it did on the first day. Invest in Basso Composite technology, it’ll pay dividends for your cycling future.

  • 3B Vibration Dampening: The advantages of the 3B clamp system are multiple. Beautiful because of its simplicity and nearly invisible form, functional thanks to its ingenious design. Not only does the triple point clamping system confer a lightweight, extremely sturdy and reliable grip but it is designed in such a way to allow for an incredible amount of vibration dampening as well. Strong and safe grip, increased comfort and sleek design from one tiny component that most overlook.
