When Geraint Thomas crosses the finish line at the end of the sixth stage of the Tour of Britain in Cardiff this Sunday, it will mark the end of his long and successful career as a bike rider.

The Welshman has earned respect from cycling fans worldwide during the course of his 19 years as a professional racer not just for his results, but his honest riding, and sheer grit.

It's gold, green, white, and red for Thomas. It looks like a nod to the welsh colours, and his pair of Olympic Team Pursuit titles. Though it also encompasses his National road race, and Commonwealth Games road race title for Wales. Not a bad mix all told. (Image credit: Ineos Grenadiers)

Another close up of the dragon. We don't know for sure yet, but we assume Thomas will be riding this special bike all week. No doubt the team mechanics will have it looking perfect each day. (Image credit: Ineos Grenadiers)

Does it get much more bling? I'm betting Thomas gets fresh white bar tape every day, and why not? Spot the victories listed at the front of the bikes top tube. (Image credit: Ineos Grenadiers)

The top tube has some key victories listed, though there's plenty more that could have gone on there. Thomas has won just about every major stage race outside of the three week long Grand Tours. (Image credit: Ineos Grenadiers)

It's a nice mix of colours that really works, too much white can be overkill sometimes. The rest of the bike's build looks stock with the team's standard Dura-Ace C50 wheels and Di2 groupset fitted. Spot the 'Edizione Speciale' sticker on the chainstay. (Image credit: Ineos Grenadiers)

Seatpost painted to match, and a Prologo saddle with a cutout for Thomas. Spot the white paint mark used to measure rider setback on the saddle; a pro move from the mechanics. (Image credit: Ineos Grenadiers)

This bike doesn't actually appear to have a name tag; it's obvious who it belongs to. Will this bike end up in a museum, or will Thomas be allowed to keep it? We wonder. (Image credit: Ineos Grenadiers)

There's another tiny Welsh flag on the back of the seatpost; Thomas will be racing on home roads at the weekend after all. Below you can watch an Instagram video of Thomas checking out his bike with team mechanic Richard Lambert. (Image credit: Ineos Grenadiers)

He has ridden and raced bikes from an early age up to a national level on the road and track, and has ridden and competed in most disciplines. He has a keen eye for pro-team tech and enjoys spotting new or interesting components in the wild. During his time at Cyclingnews, Tom has already interviewed some of the sport's biggest names including Mathieu van der Poel, Tadej Pogačar and Alberto Contador. He's also covered various launches from brands such as Pinarello, Ridley, Specialized and more, tackled the Roubaix Challenge sportive aboard his own rim-brake Cannondale SuperSix Evo, tested over 20 aero helmets in the wind tunnel, and has created helpful in-depth buying advice relating to countless categories from torque wrenches to winter clothing.
