Currently holding the pink jersey in the Giro d’Italia, Tom Dumoulin will be looking to solidify his place at the top of the general classification with a strong performance in Sunday’s 40.5km stage nine time trial around Chianti.

The Dutchman will set about that task on his Giant Trinity time trial bike, which has one of the most distinctive profiles of any time trial bike in the pro peloton, with its bolt-upright seat tube and seriously cut-out seat tube. However it’s the less obvious details that probably have the biggest aerodynamic benefit, such as the dead-straight bladed fork that keeps the front brake out of the wind, and the deep head tube.
Shimano sponsorship means that Dumoulin is using Shimano Dura-Ace Di2, with a massive 56 tooth big ring at the front, and the electronic shifting allows him to have shift buttons on both the aero extensions and by the brake levers on the handlebars, meaning that he can change gear even when sprinting out of the corners or when climbing.
The finishing kit all comes from Pro, which is one of Shimano’s in-house brands, with a Pro Disc wheel and tri-spoke, and an Aerofuel time trial-specific saddle. One final interesting detail is that Giant-Alpecin are still using last year’s Vittoria Corsa tyres rather than the 2016 graphene-infused versions, a choice that the team mechanics say is down to the old version’s lower rolling resistance, while the 2016 tyre is being used in normal road stages due to its better puncture protection.
