Kú TF1 is not a stock superbike pulled from a size run. It is a rider-specific custom triathlon and time-trial platform, and it only makes sense when the frame, fork, front end and build decisions follow your position instead of forcing you to adapt around the bike later.
This page is here to explain the bike itself, not just repeat general fit language. If you already want a fit-first TF1 direction, use the Kú referral path. If you still need the buying and sizing decision clarified first, use the booking hub or Custom Bike Sizing.
This page is for riders who want rider-specific direction before they place an order or commit to a build path. It is especially useful when the bike decision, cockpit decision and position decision need to stay aligned from the start.
A premium bike does not remove the need for clean decisions. It raises the cost of getting them wrong. If the frame choice, stack and reach window, cockpit logic or contact points are judged too late, you can end up buying precision and still living with compromise.
That is why I start with your position. The goal is not a dramatic sales pitch. The goal is a stable, repeatable direction you can actually ride outdoors.
TF1 is a rider-specific custom platform ordered through an authorised fitter. That matters because the value is not only in the frame shape. The value is in how the bike can be built around your coordinates, your cockpit needs and the way you actually race or ride.
Official TF1 details such as frame-specific fork length, the high steerer pivot box between the rider’s arms, the FAST fork air stream approach and the HAS brake-line connector all matter because they affect setup freedom, service practicality and how cleanly the front end can be realised around the rider.
You are also not locked into a generic finish. Personalised paint and decals are part of the custom route, which makes sense only after the fit and build brief are clear.
Use the booking path if you already know what you need, or start with the closest service page and decide from there.
