Lizzie Deignan’s winning Paris-Roubaix bike | 1x, tubeless & discs
Paris-Roubaix has always been a testing ground for radical and experimental setups and it was no different during the inaugural edition of the Paris-Roubaix Women race, with Lizzie Deignan winning aboard a Trek Domane with 1x gear, 30mm tubeless tires and disc brakes.
Deignan swapped the lightweight and aerodynamic Trek Emonda for the Domane endurance bike for the cobblestones of northern France. But while we’re used to seeing riders change frames to cobblestone, the rest of Deignan’s build was less familiar.
These images show Deignan’s bike straight out of the finish line, covered in mud from the 17th sectors of paving stones. Deignan, former winner of the Tour of Flanders, attacked on the first stretch of cobblestone to grab a dominant victory, remaining flawless over more than 80 km.
1x for the Hell of the North
Disc brakes can now be the norm in professional cycling, and we expect every team in Sunday’s men’s race to use discs after Ineos-Grenadiers gave up rim brakes, but 1x drivetrains n ‘failed to make a significant impact on the road outside of the time trials (and a failed experience of the Aqua Blue Sport men’s team in 2018).
However, Deignan’s Trek-Segafredo women’s team opted for a 1x setup for Roubaix, pairing a 50-tooth front chainring (fitted with a Quarq power meter) with a 12-speed 10-33t cassette and rear derailleur. SRAM Red eTap AXS wireless electronics.
With the 116k Paris-Roubaix Women taking place mostly on flat roads, Deignan hardly needed a front derailleur, although the British rider did put in a K-Edge chain catcher to provide additional safety on the hard paving stones.
The tide is turning for tubeless
As for the choice of tires, the 2021 editions of Paris-Roubaix could be the races where tubeless tires will truly prevail at the top of road cycling.
Professional riders have used tubulars since the dawn of time, with handmade Dugast and FMB tubulars commonplace on cobblestone classics of years past, but this commitment is starting to show signs of waning.
Julian Alaphilippe won the Men’s World Championship road race on tires and tubes last weekend – his Deceuninck-QuickStep team used tires throughout the 2021 season – and tubeless tires will be used extensively in this weekend’s Roubaix races, both in the Saturday Women’s edition and the upcoming Sunday Men’s Race.
Deignan’s Bontrager Aeolus RSL 37 wheels were fitted with 30mm wide Pirelli P-Zero Race TLR tires, providing extra comfort and flat protection on cobblestones, as well as the ability to ride at lower pressures in rough terrain. slippery conditions.
Blips on the bars, but no blips for Deignan
Other notable features of Deignan’s bike include SRAM shifters on the handlebars – allowing for quick shifts from the peaks, where riders normally prefer to place their hands as they bounce off the pavement – and a Wahoo Elemnt Bolt computer. .

Trek’s Domane frame is more familiar than the rest of the build but is still worth mentioning, having been put to good use in classics since its launch in 2012. The third-generation Domane SLR, introduced in 2019, offers the Trek comfort. improving IsoSpeed technology on the front and rear of the frame.
The rear IsoSpeed is based in the top tube, having been moved from its seat tube location on the previous edition of the bike. The L-shaped seatmast is supported by the top tube, with elastomer to add cushioning and a hidden slider to adjust compliance.
This is a design first seen on the Trek Madone SLR and now worn on the new Trek checkpoint gravel bike, launched earlier this week (although the Checkpoint’s IsoSpeed isn’t adjustable).
Bloody but victorious
While Deignan’s bike had plenty of built-in cushioning thanks to big tires and IsoSpeed, with the headset placed in a toggle cup to add comfort to the front of the bike, Roubaix’s cobblestones still did. havoc, with blood visible on the 32- year bar tape. This is what Paris-Roubaix will do without gloves.
The final touch to mention is the Deignan bib, filthy on the seatmast after 30km of muddy cobblestones.
But, despite having received the number 13 of the day, Deignan could not stop Deignan while she made history in Roubaix.
