An Italian All-Road Bike for Every Day, Not Just Race Day
The Basso Astra keeps its road racing DNA but adds the stability and comfort that real riders want every day. Compared with the previous Astra the stack is 12mm higher and the reach 3mm shorter, the seatstays are dropped, and there is room for 35mm tyres so you can leave the tarmac for light gravel. It is UCI approved and handmade in Italy.
This build runs Shimano 105 Di2 12-speed with hydraulic discs on Mavic Aksium wheels. Cables are fully integrated through Basso's Paradigma system, so the stem can be swapped or removed without disconnecting anything. You can also order it with a Magene power meter crank fitted.
Why we chose this for our customers:
- 980g Italian carbon frame: Toray high modulus carbon, made in house at Basso in Italy, with a 2 year warranty.
- Shimano 105 Di2 12-speed: Electronic shifting with hydraulic disc brakes and 160mm ICE rotors.
- All-road ready: Room for 35mm tyres, dropped seatstays and a more relaxed position for long days.
- Easy to live with: Paradigma integration keeps steering light and makes cockpit changes simple, with a hidden 3B seat clamp.
