Why is the 323mm Vector Sprint Handlebar UCI compliant when it measures 323mm wide, and not the UCI minimum of 350mm?

The 323mm measurement refers to the handlebar width measured centre-to-centre at the drops. The UCI regulations measure handlebar width differently, using the external width of the handlebars, including the grip area.

The Vector Sprint Handlebar measures 350mm from outside-to-outside, making it compliant with the UCI minimum handlebar width regulation that comes into effect from 2027. While the handlebar is 323mm centre-to-centre, its external width satisfies the UCI's 350mm minimum requirement.

What is the difference between the 323mm and 350mm Vector Sprint Handlebar?

The primary difference is width. The 350mm version is 27mm wider than the 323mm version when measured centre-to-centre at the drops.

All other features remain the same, including the handlebar shape, reach, drop, ergonomics, stiffness characteristics, and compatibility.

How do I choose the correct handlebar width for track sprinting?

Choosing the correct handlebar width depends on your racing experience, bike handling preferences, shoulder width, and current setup.

Riders transitioning from road cycling often prefer wider handlebars because they feel more familiar and offer a similar riding position to their road bike. Riders with narrower shoulders may be able to use narrower handlebars without compromising control or comfort.

Ultimately, the best handlebar width is one that provides confidence, control, and an aerodynamic riding position.

Are narrower handlebars faster?

In many cases, yes. Narrower handlebars often test faster in the wind tunnel because they reduce the frontal area of the rider and bicycle system.

However, aerodynamics is only one part of performance. A handlebar that is too narrow may negatively affect comfort, stability, or rider confidence. The fastest setup is usually the narrowest position that still allows the rider to produce power and maintain control.

What are the 2027 UCI handlebar width regulations?

From 1 January 2027, the UCI requires all drop handlebars used in track competition to have a minimum external width of 350mm.

This measurement is taken from the outside of one side of the handlebar to the outside of the other side, including any bar tape, grips, or accessories that form part of the handlebar assembly.

Why did Velobike develop the Vector Sprint Handlebar?

The Vector Sprint Handlebar was developed as the successor to the Altias Sprint Handlebar.

During ongoing aerodynamic development and athlete testing, additional opportunities were identified to improve both aerodynamic performance and mechanical efficiency. The Vector Sprint Handlebar incorporates these learnings into a refined design intended to maximise performance for modern track sprinting.

Can I use the Vector Sprint Handlebar for endurance and mass-start racing?

Yes. The Vector Sprint Handlebar can be used for endurance and mass-start racing disciplines.

Sprint handlebars are typically designed to be stiffer and optimised around an aerodynamic riding position in the drops. As a result, they may feel more aggressive than traditional endurance-focused handlebars and may be less comfortable during extended periods of riding.

How does handlebar width affect aerodynamics and power output?

Narrower handlebars can reduce aerodynamic drag by reducing the frontal area of the rider and bicycle system.

When combined with a well-executed bike fit, riders can often achieve aerodynamic gains without compromising power output. The goal is to find the narrowest position that remains sustainable, comfortable, and allows the rider to maintain optimal control and performance.
