But to start 2016 Sagan has taken it one step further by seemingly shunning a cycling tradition and competing with hairy legs.
voyeur eagle-eyed snapper got a picture of Sagan with some pretty decent foliage on his pins in the team time trial at the Tour de San Luis.
Maybe this is Sagan's way of levelling the playing field? Maybe he's testing out a new aerodynamic theory? Maybe he just doesn't know the Spanish for 'one Bic please'...
Even with the hairy legs, Sagan and co rode to fourth in the opening stage in San Luis, finishing 23 seconds down on winners Etixx-Quick Step.
With hills and mountains to come on the next six stages of the race, Tinkoff's general classification hope Rafal Majka will have some work to do to get time back on the likes of Nairo Quintana, who sits eight seconds back on leader Maximiliano Ariel Richeze.
