“This is no coincidence” - UCI controversially impose last-minute ban on Visma’s tyre pressure system pre-Paris-Roubaix as team DS fumes at decision

Paris-Roubaix is a race decided by margins. Over more than 50 kilometres of cobbles, the difference between winning and losing is often not strength alone, but how well a rider and their equipment can survive the chaos.

That is what makes the UCI’s late decision to ban Visma’s tyre pressure system so significant. Just days before the 2026 edition, one of the few tools designed specifically for the unique demands of the Hell of the North has been taken off the table.

Unlike other Monuments, Paris-Roubaix forces riders to constantly transition between smooth tarmac and some of the most brutal road surfaces in professional cycling. Managing tyre pressure across those changes is a long-standing challenge.

Visma’s system offered a solution. Riders could adjust pressure while racing, lowering it for grip and comfort on the pavé, then increasing it again for speed on the road sections. In a race where positioning, punctures and bike handling can decide everything, that flexibility had clear value. And in 2026, it may have mattered more than ever.

With tighter early sectors and less recovery time between cobbled stretches, this year’s route is expected to place even greater stress on equipment from the opening phases of the race.

Despite being used in competition, the system will not be seen on Sunday. “We received a letter two weeks ago stating that the system is banned until the end of the season,” said Mathieu Heijboer, Head of Performance at Team Visma | Lease a Bike, speaking on the In De Waaier podcast.

The UCI’s reasoning centres on commercial availability rules, with the governing body questioning whether the system meets the requirement after the company behind it filed for bankruptcy earlier this year.

For Visma, the explanation has not brought clarity. “A vague story.”

The system has since returned to the market following a restart of the company, while its use in recent races had raised no concerns. “There was also no prior warning. In fact, we still used it at GP Denain.”

That lack of notice is what sharpens the sense of frustration within the team.

Paris-Roubaix is uniquely sensitive to equipment decisions, and the timing of the ruling has not gone unnoticed. “That is, of course, no coincidence.”

With penalties ranging from warnings to disqualification, there is no room for risk. “That’s a risk we are obviously not going to take.”

For Wout van Aert, the impact is immediate. The Belgian remains in pursuit of a first Paris-Roubaix title, and in a race where small advantages can define the outcome, the removal of a system designed specifically for the cobbles is not insignificant.

Asked directly whether it affects his chances, Heijboer was clear. “Yes.”

Paris-Roubaix rarely follows expectation. Mechanical issues, positioning and sheer unpredictability shape the outcome as much as raw power. This year, however, one variable has been removed before the race has even begun.

In a Monument defined by uncertainty, that alone could prove decisive.
