The Phenom: What is the exact Paul Seixas bike size for 2026?
If you are searching for the exact Paul Seixas bike size, you are in the right place. At just 19 years old and measuring 1m86 tall, the French teenager racing for Decathlon CMA CGM is tearing the road cycling world apart. He’s been winning across the board for years, dominating road, time trials, cyclocross, and mountain biking.
He put everyone on notice by taking 3rd at the 2025 European Championship Road Race behind only Pogačar and Evenepoel. But his 2026 season has been an absolute clinic. He started with a direct confrontation against Tadej Pogačar at Strade Bianche, finishing a spectacular 2nd just seconds behind “Poggy.” Then, he finally broke France’s multi-decade curse of missing WorldTour stage race victories by dominating the Tour of Basque Country, taking three stages and the GC ahead of Florian Lipowitz (who took 3rd at the Tour de France in 2025).
If that wasn’t enough, he just won La Flèche Wallonne 2026 by obliterating the Mur de Huy climb in 2 minutes 43 seconds. For context, Pogačar did it in 2:46 back in 2023. Seixas is undeniably France’s legitimate hope for a Tour de France victory. His emergence adds a massive new variable to the top-tier GC rivalry against Pogačar, Vingegaard, Lipowitz, Del Toro, Ayuso, and Evenepoel, setting the stage for explosive battles in the upcoming grand tours, including the Vuelta a España.
Analyzing the Paul Seixas Bike Size and Fit
When looking at the Paul Seixas bike size, his setup is pure business. He races on a size L Van Rysel RCR-R. For a 1m86 rider, a large frame makes sense, but it’s the cockpit that shows how aggressive his fit truly is. He runs a massive 140mm length by 400mm width Deda integrated stem and bar setup, completely slammed with a negative stem angle to get as low and aero as physically possible.
Understanding the Paul Seixas bike size means looking closely at his component choices. Despite his height and long levers, he opts for 170mm SRAM Red crank arms pushing a massive 54/41t chainring combo and a 10-36t cassette. The shorter cranks allow him to stay tucked over that slammed front end without closing his hip angle, keeping his pedal stroke perfectly open when climbing gradients like the Mur de Huy.

Frequently Asked Questions
Why does Paul Seixas use 170mm cranks on a size L frame?
Shorter cranks like 170mm open up the hip angle at the top of the pedal stroke. For a 1m86 rider like Seixas, this allows him to maintain a highly aggressive, slammed aerodynamic position on his Van Rysel RCR-R without compressing his diaphragm. This keeps his power output and cadence highly efficient on steep climbs like the Mur de Huy.
How much does the Decathlon Van Rysel RCR-R weigh?
A fully built WorldTour Van Rysel RCR-R with the new SRAM Red AXS groupset, SwissSide 550 Carbon wheels, and a Deda integrated cockpit hovers right around the UCI minimum weight limit of 6.8kg, making it a pure climbing weapon.
What saddle does Paul Seixas ride?
Seixas races on a Fizik saddle. Crucially, he mounts it to a 0mm offset Van Rysel seatpost, which pushes his center of gravity forward directly over the bottom bracket to maximize his power transfer.
Will Paul Seixas race the Tour de France in 2026?
After his massive GC victory at the Tour of Basque Country and his record-breaking win at La Flèche Wallonne, Seixas is on the fast track. Decathlon CMA CGM relies on him as France’s top GC hope, putting him squarely in the crosshairs for the Tour de France and the Vuelta a España.
