Making custom the new standard

UCI-legal, custom Time-trial handlebar extensions, made for you.

The TTX will not just give you some marginal gains, it will give you significant gains. The direct effect have been measured in the windtunnel to give an advantage between 1.4 and 5.9% on the CDA value of the tested rider. But we do not believe this is actually the biggest gain, with the position and cups made especially for you and your position, it will make holding your most aerodynamic position easier and more comfortable than ever.

The TTX is 100% UCI legal, there is written prove from the UCI that it is allowed in competition.


Custom built for you

After we have received your measurements, we make a 3D printed plastic version for you to test on a trainer.

Custom Position

Custom length, tilt, inward angle and many more to accompany your personal position. All within UCI constraints.

Perfect integration

With your current basebar/bike setup, by smart solutions and fit to original spacers. For example our unique monobridge system for monoriser systems such as on Speedshop51, Trek Speed concept and Cervelo P5 risers.

Measurement and Design

We offer two different measurement methods:

-Offline: We plan a moment for you to visit us at our workshop in Eindhoven, the Netherlands. We measure you, your bike and talk about your needs for the extensions.

-Online: We send you a measurement guide to execute together with a friend.

When we have all required measurements, we design a set of extensions perfect for your fit and needs.


The design is first send to you for visual inspection. When the custom bars are approved the proposal is 3d printed and send to you. This way, you can check the fit on both your body and your bike and feel what the final product will be like. This print is not suited for usage on the road!


When the final verification step is done, we start our production. Your custom time trial bars are laserprinted from AlSi10Mg. This is an aluminium magnesium alloy with excellent repeatability, so it enables us to simulate the strength of any design we make before production.


Current cost of the whole process (Measuring, 3D prints and the end product) for a UCI-legal product starts at €1800, with a 50% deposit.
