Geraint Thomas will ride his final Tour de France as he has spent most of his time at la grande boucle – onboard a Pinarello Dogma.
Thomas made his Tour debut in 2007, riding with the Cannondale-sponsored squad, Barloworld, for two editions. He moved to Team Sky in 2010 and has been on Pinarellos ever since.
His Dogma F build for the 2025 Tour de France – Thomas’ 18th edition of the race – is largely unchanged since its Tour debut last year.

The bike rolls on a full Shimano-Dura Ace R9200 Di2 groupset and matching C50 wheels.
We expect Thomas will ride these for the flat opening stages, although he and his teammates will likely swap between these and their arsenal of Princeton wheels depending on the stage and their preferences.
The wheels are fitted with Continental GP 5000 TT TR tyres. In a move rarely seen in 2025, Thomas is running a decidedly old-school 25c tyre on the front of his bike.

Mounted to the 21mm-wide Dura-Ace rims, the tyres plump up to 27.4mm – according to Simon von Bromley’s trusty vernier calipers. Even still, 27mm is narrow by modern standards, with many riders opting for 30 or 32c tyres.
Out back, Thomas is running a more typical 28c tyre, which plumps out to 30.66mm mounted.
Thomas will run 54/40t chainrings paired with a wide-range 11-34t cassette. He uses 172.5mm cranks. That’s fairly long by current trends – GC contender Jonas Vingegaard is riding 160mm cranks, for example – but it’s not unusual for the 1.83m tall Welshman.

The cranks spin on an Italian-threaded Shimano Dura-Ace bottom bracket. Pinarello is one of the very few brands that still uses an Italian standard bottom bracket shell.
This curious standard doesn’t feature a reverse-thread on the driveside, and the shell is slightly wider than a standard 68mm ISO bottom bracket at 70mm.
Hidden behind the crankset on the bottom of the chainstay is a small 3D-printed chain catcher. This is glued in place and presumably reduces the chances of chainsuck if the chain unships on the inner ring.
Doubling up on chain security, Thomas is also running a conventional K-Edge chain catcher mounted to the front derailleur mount.

Thomas’ cockpit is very narrow, measuring only 28cm wide between the hoods. Such a narrow setup will be outlawed by the UCI from January 2026, with new rules mandating a minimum 320mm width between the hoods.

Of course, Thomas probably couldn’t care less – although he’s expected to take up a management role at Ineos Grenadiers, he retires from racing at the end of this season. The old dog might as well enjoy the aero gains while he can.

The bar, as measured at the ramps, is around 35cm wide, centre-to-centre. We measured the stem of the bike’s matching one-piece cockpit at around 140mm long.
Thomas’ build is rounded out with spindly Elite Leggero Carbon bottle cages and a Prologo Nago R4 saddle.
All in, the bike weighs a respectable 7.455kg.
