At his home national Tour, Silvan Dillier (AG2R La Mondiale) has given his national road race champion's jersey plenty of air time at the front of the Tour de Suisse, managing to embed himself in the breakaway for stages 4 and 5 of the race.
Matching his bold red-and-white national champion's jersey, Dillier has been riding custom-painted Factor framesets in the Swiss colours during the race. Dillier opted for the aero Factor One for stage 2 and the lighter Factor O2 for the stages with more climbing later in the week.
The aero frameset from Factor has a few unusual design features, even for an aero-specific bike, taking the hinged external steerer design usually seen on time trial bikes and a split down tube, again inspired from the brand's time trial frameset.
The design of the frame is expectedly in the contrasting red and white Swiss national colours, with the Swiss national coat of arms featuring at the bottom of the down tube and on each of the fork shoulders.
Dillier's nickname – 'Sid' – also appears on the top tube at the junction with the seat tube.
AG2R La Mondiale pair their Factor bikes with wheels from French brand Mavic and drivetrain components a mix of Shimano and SRM. The Shimano Dura-Ace R9150 rear derailleur has been modified with CeramicSpeed's OSPW system, which has also been customised for the Swiss champion with red pulley wheels.
The Factor One comes with a proprietary aero cockpit system and seat post, with Fizik providing Dillier with a colour-coordinated Fizik Arione saddle.
