A triathlete is not a cyclist and triathlon bikes have in many cases become derivatives of time trial bikes due to strict UCI regulations. A triathlon bike should therefore not be a time trial bike with many adjustments made to the bike set up in order to accommodate a rider or his performance. But this is what’s happened until now and hence there has been little development in triathlon. “Accommodation” is unfortunately part of bike-fitting as many cyclists still go to the fitter after having purchased their bike, expecting a perfect position, despite maybe having purchased the wrong bike. This often presents a big challenge for the fitter and sometimes frustration for the cyclist. You got it; it should be done the other way round: a pre-fit (called on this site bike-sizing), should be planned prior to the bike purchase to make sure the cyclists will enjoy their rides with the bike that suits best to their needs.

As mentioned before, a triathlete is not a cyclist and needs a different bike. Some brands understand that difference and very recently began to distance themselves from the UCI rules. A big step forward! But still not big enough. After the bike-sizing, the triathlete might have the choice between several tri-bikes that, again, will have to be adapted (sometimes approximately) to his fit coordinates. But at least, if the fitter did a good job, the triathlete can be sure to order the right frame size with the right components.

One brand dares to go one big step further: Kú Cycle. How big? They build a rider-specific bike underneath each athlete based on the fitter’s prescription. They aim for the perfect fit between body and machine. And what a machine: the KÚ TF1.

What makes the Kú TF1 different from all the other triathlon bikes?

  • It is rider-specific, built-to-order for just one athlete
  • It can only be purchased after a thorough pre-fit by Kú authorized fitters
  • It is fast, very fast. What makes it so damn fast? Watch the short video with Richard Mc Ainsh, Formula 1 engineer.
  • The paint scheme can be customized
  • It has the smallest packing size. The front – fork and cockpit -. can easily be separated from the frame to fit in a travel case that can fly as a second suitcase

These are just a few points characterizing Kú Cycle and their TF1. I invite you to discover the revolution on their website. Marvel and enjoy.
