Tadej Pogačar will ride Paris–Roubaix 2026 on a Colnago Y1RS Dark Edition fitted with 35mm-wide Continental GP 5000 S TR tyres that measure 38mm when mounted to his 25mm-wide ENVE SES wheels.
The reigning World Champion will also run a 56-tooth 1x drivetrain. As far as we’re aware, this is only the second time the Slovenian superstar has used 1x in a road race following his win at Milan-San Remo 2026.
Right on the limit
Tyre tech is always the key talking point of Paris-Roubaix, with riders opting for ever wider options in recent years.
32mm has become the de-facto norm, but Pogačar takes this further than anyone yet, opting for 35mm tyres.
When mounted to his ENVE SES wheels, these measure closer to 38mm.
This setup likely tickles the absolute limit of the UCI’s regulations, which limits a wheel and tyre combo to a maximum diameter of 700mm. A 40mm tyre mounted to a 700c wheel generally sits outside this limit, so a 38mm tyre is likely to be close to this.
It also pushes his Colnago Y1RS’ tyre clearance to the max, with only a small gap between the crown of the fork and the tyre.
The weather in the run-up to the race and the forecast for Sunday is currently dry, so dusty conditions will prevail at Roubaix. If wetter conditions were expected, the team would likely have to use a narrower tyre.
His rear tyre is more conventional at 32mm wide, though it again measures wider than the stated width – closer to 35mm.
The tyres are mounted to hookless ENVE SES wheels. He’s running the 60mm deep 6.7 up front and the 56mm deep 4.5 out back.
Pogačar will not run inserts at Paris-Roubaix. An ENVE spokesperson present at the team bus explained that the brand doesn’t recommend using inserts with its wheels.
This position stands apart from other riders and teams we’ve spoken to, who value the run-flat security of inserts.
1x for the the second time
Another key Roubaix-specific change for Pogačar is the move to 1x.
The rolling parcours of Roubaix suit 1x, so it’s a common switch among riders for the race, offering a moderate reduction in weight and improved aero performance.
Speaking to BikeRadar, a team mechanic said the team had tested running 1x throughout December, but no final decision was taken for Roubaix until this week, when Pogačar finally settled on a single chainring.
Pogačar is using a 56t CarbonTi chainring mounted to 165mm long Dura-Ace R9200 cranks.
With no clutch, Shimano doesn’t officially endorse 1x with its Dura-Ace road groupsets, so a K-Edge chain catcher is used to improve retention on the cobbled sectors.
He’s also switched from his previous Frames and Gear direct-mount Shimano hanger to a Carbon-Ti option – in keeping with the rest of the tasty lightweight mods on his bike.
