Kinesis Racelight Aithein Frameset available in Black, Green and Orange

Kinesis have put everything we have learned during over 12 years of alloy frame design and manufacture into this completely new and very advanced, alloy road frame.

The focus has been on carbon in the last few years, but we believe that by putting the same development into alloy tubing, we have created a frame that rivals carbon in many ways and hands-down beats it on price.

Advanced, Superplastic Formed, ‘Anti Gravity’ seat tube, adds immense core stability to the frame, allowing us to lighten the main tubes.


  • Super lightweight: 1200g for 56cm frame (prototype estimation).
  • 330g monocoque carbon, taper 1.5” fork.
  • Taper Head tube.
  • ‘BB86’ Bottom Bracket shell, Shimano press-fit standard.
  • Tough anodised frame finish with laser-etched graphics and special decals.
  • Seat clamp not included

Best ever frame for the money! Light, stiff and flashy looking! If you can`t afford to buy a very good quality carbon frame, do not hesitate to buy a high quality aluminium fame like this. The stiffness and the light weight of the frame are noticable. I can`t wait to see what Kinesis will put out in the future.
Great, very stiff, race like frame. It corners like crazy, may feel twitchy at first but its beautiful. If You are looking for a race or just fast and aggressive geometry bike, just buy it, it`s worth it. Few pointers so you don`t do mistakes like me: You don`t need to install race crown on fork just put bearing on it. Don't use star nut because fork is full carbon, use compression plug.
Sublime. Greatest bike I've ever had and I've had a lot
