Wearing the yellow jersey after riding into the lead of the Tour de France is a career highlight for any cyclist. In addition to donning the iconic maillot jaune, they usually get to ride a specially painted bike equipped with as many matching components as their mechanics can find. We saw a similar exercise carried out last year, where Cannondale worked around the clock to paint a Lab71 SuperSix before escorting it in a Porsche 911 Carrera 4 GTS Cabriolet to ensure it arrived in time for him to defend the jersey in Toulouse.To the Tour! Upon completion, the frameset was escorted to Brussels Airport for an express flight to the Hautes-Pyrnes (Image credit: Ridley Bikes)The current race leader, Torstein Tren, has this honour and his Uno-X Mobility team has pulled out all the stops to commemorate his remarkable route to yellow. From its factory in Belgium, Uno-X's bike sponsor Ridley delivered a yellow Noah Fast 3.0 to southern France within 30 hours of Tren pulling on the leader's jersey. In May 2022, Tren discovered he had returned an abnormal doping test result. His team doctor interpreted this as a sign he could be ill, and urged his rider to see his GP. As pain in his testicles increased, an ultrasound scan revealed he had testicular cancer. When his left testicle was removed just 41 days on from his doping alert, a 15mm cancerous tumour was found inside. But it hadn't spread, enabling him to make a full recovery and restart racing in August 2022. The raw carbon frameset offsets the yellow-painted headtube quite exquisitely.

On stage four of the 2026 Tour de France, he joined a strong breakaway powered by Mads Pedersen's Lidl-Trek teammates, who succeeded in setting up Tren's fellow Norwegian for stage victory in Foix. Tren now leads EF Education-EasyPost's Sean Quinn by 28 seconds in the general classification, and more importantly, he is ahead of race favourite Tadej Pogaar by nearly eight minutes. Being a good climber, this buffer could help him retain yellow through the mountainous second week.Ridley founder Jochim Aerts personally spraying the Noah Fast frame (Image credit: Ridley Bikes)Now let's take a close look at his custom Ridley Noah Fast 3.0, which was sprayed by the brand's CEO, Jochim Aerts, in a return to his frame-spraying roots. The third-generation bike is considered one of the peloton's best aero bikes, thanks to a combination of minimal frontal area and deep tubes designed to take advantage of the 'sailing effect'.The raw carbon frame is essentially the same stock Ridley Noah frameset but the red accents have been ditched for yellow (Image credit: Ridley Bikes)The byproduct of this chunky tubing is weight. At the Opening Weekend, we weighed one of Tren's teammates' bikes at 8kg, which is on the heavy side for a WorldTour bike. In light of that, Ridley hasn't gone all out on the yellow paint just spraying parts of the head tube and top half of the fork saves 100g over a full coat.

As for the yellow details, expect to see yellow handlebar tape, wheel decals, and SRAM stickers on the levers and cranks. Whether the Norwegian uses his custom Ridley Noah Fast for the first mountain stage of this year's Tour de France between Pau and Gavarnie-Gdre, we'll have to wait and see we suspect he'll be on the unreleased Falcon RS lightweight bike to ensure he stays in yellow for the coming stages.
