The Kinesis Aithein is the fastest bike in the Kinesis line-up. The new Aithein is faster, more comfortable, and more fun, making it the perfect choice for racing the local crit, club sportives or winning sprints for the line.

Using advanced aluminium construction techniques, we've created a lightweight frame that rivals carbon bikes. Thanks to Superplastic Forming (SPF), we've minimized weight while maximizing stiffness and strength. This results in a high-performance frame that efficiently transfers rider energy into forward momentum.

The new Aithein offers 30mm tyre clearance, providing speed and grip on modern, larger-volume tyres. Paired with the Futura Road fork from Columbus, known for its impeccable ride quality and unmatched vibration damping, the Aithein is designed for flat-out performance.

Super Plastic Formed Alloy Frame — constructed from tubes that are created with an advanced manufacturing technique named Superplastic Forming (SPF), which involves heating the alloy until it exhibits superplasticity, and then creating complex tube shapes using gas pressure.

Super Light: The Aithein Disc frame tips the scales at just 1.60kg (53cm).

Columbus Futura Road Disc Fork — T700S and HFM Carbon Fibre Monocoque construction, 45mm rake, 440g fork. Stiff with high vibration damping for a smooth ride.

30mm Tyre Clearance — It is becoming widely accepted that wider tyres offer more speed, more grip and more comfort on real world surfaces. The new Aithein Disc will take up to 30mm tyres so you can choose the right tyre for you and your riding conditions.

Kinesis Rider Fit Geometry — Geometry adjustments have been made to ensure a better fit across a greater range of rider dimensions. As a result there is more consistent handling across sizes, less toe overlap, and more intuitive sizing.

68mm Threaded Bottom Bracket — Threaded BBs allow you to use reliable, creak free bottom brackets that withstand year round British conditions.

Adaptable Cable Ports — Thanks to interchangeable cable entry points you can run exactly the routing you need, ensuring there are no excess holes into the frame.

Wireless Electronic / Mechanical / 2x / 1x Compatible — The Aithein frame is designed to work with mechanical and all wireless electronic groupsets.
