Colour: Black
For 2020 the Aithein is back to reclaim its place as the fastest bike in the Kinesis lineup. Our premium aluminium race frame is faster, more comfortable and more fun than ever before. Whether its racing the local crit or winning the sprint for the sign, the Aithein is the bike to get you there faster.

Using advanced aluminium construction techniques, we’ve created a frame that truly questions the need for a carbon bike. Thanks to the advanced manufacturing technique called Superplastic Forming (SPF), we’ve minimised weight whilst maximising stiffness and strength where you need it. The result is a high-performance frame that excels in transferring rider energy into forward momentum.

The new Aithein features 28mm tyre clearance for speed and grip, allowing you to ride at full speed on every road surface. To complement the frame we chose the excellent Futura Road fork from Columbus, known for its impeccable ride quality, and unmatched vibration damping.

Riders looking for more stopping power will be pleased to know that the Aithein frame is also available in a disc compatible option, featuring thru axle front and rear. No matter how you choose to ride, if you choose to ride fast, choose to ride Aithein!


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 exhibits superplasticity, and then creating complex tube shapes using gas pressure.

Columbus Futura Road Fork
T700S and HFM Carbon Fibre Monocoque construction, 45mm rake, 350g fork. Stiff with high vibration damping for a smooth ride.

28mm Tyre Clearance
It is becoming widely accepted that wider tyres offer more speed, more grip and more comfort on real world surfaces. The Aithein will take up to 28mm 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 BB
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.

Electronic / Wireless / Mechanical 1x Compatible
The Aithein frame is designed to work with whichever groupset you choose to run.
