Bike check: Geraint Thomas' Pinarello Dogma F at the Tour de France

Geraint Thomas's Pinarello name sticker .

Geraint Thomas says he's "95% likely to retire at the end of the 2025 season." He's going out fighting though; having already ridden to 3rd place in the 2024 Giro d'Italia, the 38-year-old now riding his 13th Tour de France in support of Ineos Grenadiers team leaders Carlos Rodriguez and Egan Bernal.

Thomas is riding the latest version of the Pinarello Dogma F, a bike that was only launched in June and which we got to ride in the Dolomites for our Dogma F 2024 review. 

Pinarello has improved the bike's aerodynamics. It's also been progressively shaving away at its weight. We weren't allowed to weigh Thomas' bike, but his mechanics claimed it tipped the scales at 7.2kg. 

At launch, Pinarello claimed a weight of 6.77kg for a size 53cm bike with Dura-Ace and 1,350g Princeton Carbonworks wheels. Shimano says its Dura-Ace C50 tubeless wheels weigh 1,461g a set, which is what the Ineos Grenadiers race on in various rim depth options. Add in 238g for Thomas' Dura-Ace SPD-SL pedals and that figure might just be possible, although the Welshman rides a size 56 bike rather than a 53.

We have more Tour de France pro bike checks on the way, but for now, why not enjoy Mathieu van der Poel's Canyon Aeroad or Tadej Pogacar's Colnago.

Thomas was a long-time Fizik saddle user, but the team has now switched to Prologo. Thomas sits on a Prologo Nago R4 PAS in 137mm width. Prologo claims a 139g weight for the carbon-railed saddle (Image credit: Josh Croxton)

As the weight of the Dogma and the Dura-Ace wheels have steadily decreased over the years, Ineos seems to have ceased its former dalliance with the Lightweight wheels brand (Image credit: Josh Croxton)

Thomas is running the wider ratio 11-34t Shimano Dura-Ace 12-speed cassette with a claimed 253g weight and six titanium and six steel sprockets (Image credit: Josh Croxton)

The team has been riding Conti tyres since its launch as Team Sky. We think these are the TDF limited edition tyres with stealthy logo's  (Image credit: Josh Croxton)

As with rim brakes, Ineos was a long-time holdout against tubeless tyres, but the last few seasons have seen the team switch to tubeless tyres in its Dura-Ace wheels (Image credit: Josh Croxton)
