Astra Chorus Bike

Basso Astra Chorus Bike

The Basso Astra Chorus Bike is built for versatility, offering a seamless transition between smooth tarmac and light off-road terrain. Designed to strike the ideal balance between road racing performance and all-road adaptability, it is UCI approved and ready for a variety of riding conditions.

While it retains a strong road cycling character, the Astra has been refined to increase comfort and stability. The frame is lightweight without pushing carbon to its limits, preserving Basso's racing heritage in a more accessible package for everyday riders. Key geometry changes include dropped seatstays, a 12 mm higher stack and a 3 mm shorter reach, creating a slightly more relaxed and upright riding position. With 35 mm tyre clearance, the Astra can accommodate wider tyres, allowing riders to explore light gravel and dirt roads with confidence.

3K Toray CA High Modulus Carbon Fibre
Handcrafted entirely in-house by Basso in Italy, the carbon frame is built to maximise rider enjoyment. Basso has long been a pioneer in carbon frame development, continually refining materials and construction methods to enhance performance, durability and ride quality.

Paradigma Integration System
Internal cable routing is achieved without compromising steering precision. Thanks to the Paradigma Stem design, the body of the stem remains cable-free, allowing for removal or adjustments without disconnecting cables. This simplifies maintenance, travel, and customisation of fit.

3B Clamp System Gen 2
The seatpost is secured with a fully hidden clamp mechanism that blends technical functionality with aesthetic appeal. This integrated system is not only lightweight and robust, but also includes an anti-vibration feature to boost comfort across rough terrain.

The Basso Astra Chorus Bike delivers an elevated riding experience, whether on the road or heading off the beaten path.
