The King is dead, long live the King the Kinesis Aithein is back to reclaim its place as the fastest bike in the Kinesis line-up. For 2023, 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 new Aithein is the bike to get you there quicker.
Using advanced aluminium construction techniques, we've created a lightweight 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.
Now with more tyre clearance the new Aithein now features 30mm tyre clearance for speed and grip, allowing you to ride at full speed on every road surface on modern larger-volume tyres. To complement the frame we chose the excellent Futura Road fork from Columbus, known for its impeccable ride quality and unmatched vibration damping.
Flat mount brake attachment and industry standard 12mm thru-axles are used on the disc brake model with GWs excellent switch lever for a clean looking and dependable set up. No matter how you choose to ride, if you choose to ride fast, choose to ride Aithein!
