Tom Dumoulin arrived at the Tour de France as Team Sunweb's general classification hopeful after finishing second at the Giro d'Italia earlier in the year. With three stages left to race, Dumoulin currently sits in second place and is a strong contender to retain a podium position by the time the race reaches Paris.

Opting to race aboard a Giant TCR for each stage, as opposed to the more aero-focused Giant Propel frameset, Dumoulin's bike is made up almost exclusively with Giant or Shimano components, excluding only the computer and tyres.
The full-carbon frameset is equipped with a Shimano Dura-Ace R9150 groupset, featuring the Shimano Dura-Ace R9100-P power meter. Dumoulin opts for a standard gearing combination of 53/39 chainrings and an 11-28 cassette, with the 1.85-metre-tall Dutchman unsurprisingly running 175mm cranks.
Dumoulin's front wheel looks to be a 42mm Giant SLR 0, while the rear appears to be a deeper 55mm version
Giant provides Team Sunweb with its SLR 0 wheels and, like Movistar's Nairo Quintana, Dumoulin appears to be running a deeper rear wheel and shallower front wheel with 55mm and 42mm carbon rims, respectively. The front wheel's Giant decals have also been replaced with Team Sunweb's hashtag #Overachieve.
Dumoulin also runs a Giant OverDrive 2 integrated carbon cockpit and appears to be using a Giant Contact SLR saddle – although with no branding on the saddle, it's likely that it's a custom or prototype version specifically designed for Dumoulin.
Team Sunweb uses Sigma Sport's Rox 12.0 computers, while Giant also produces the handlebar tape, bottle cages and bidons.
