The Astra 105 Di2 Aksium Chroma White Bike by Basso Bikes blurs the line between road racing and trail riding, delivering an adaptable cycling experience for those who love to ride every day. Driven by the Basso's DNA, without pushing the carbon to extreme, the Astra retains its lightness yet offers increased stability and comfort.

Featuring a frame entirely produced in-house in Italy with 3k Toray Ca High Modulus Carbon Fibre, this bike maintains its lightness while amplifying fun factor. It stands as a testament to Basso's commitment to durability, performance, and reliability in carbon frame design. As one of the pioneers in carbon frame technology, Basso ensures an exciting ride with the Astra.

The new frame design features dropped seatstays, 3mm shorter reach, and a 12mm higher stack height, providing a more relaxed riding experience. Adventure off the road is no problem with 35mm tyre clearance, allowing for wider tyres and rougher terrains.

A significant highlight of the Astra is its technologically advanced Paradigma Integration System, ensuring internal cable routing without compromising on the lightness and precision of steering. This ingenious system allows the easy removal of the stem body without disconnecting cables, simplifying bike maintenance and even transportation.

A part of the innovation is Basso's unique 3B Clamp System Gen 2 that keeps seatpost fixings hidden while adding an anti-vibration function to elevate your ride's comfort - a testament to Basso's blend of technological expertise and aesthetic appeal.

Equipped with Shimano 105 Di2 12x components, Hydro disc brakes, and Shimano 105 ICE Rotors 140/160mm, your ride is not only smooth, it's safe too. Add to this the comfortable San Marco Monza saddle and handlebars from Microtech All Road, and you've got a bike that's as comfortable as it is technically remarkable.

Completing the package is the wheelset from Mavic Aksium Disc, coupled with Schwalbe Lugano II K-Guard 700x28c tyres, promising unwavering stability on both road & off-road terrains.

This model truly embodies Basso Bikes' two-year warranty promise of quality and reliability, culminating in a product that straddles the best of two worlds, road and trail, all while maintaining the top-tier craftsmanship for which Basso is known.

Please Note: If you require the steerer tube un-cut, please inform us at the point of ordering.
