Gaviria raced the first stage of the Tour aboard the new S-Works Venge, launched earlier this week by Specialized as the third iteration of the American brand's aero-specific frameset.
Specialized have focused on three new designs that define the new model - the Specialized Venge VIAS - including lower weight, more aerodynamics and better handling, dubbed rider-first engineered.
Unlike the consumer versions of the new Venge, Quick-Step Floors' and Bora-Hansgrohe's - the two WorldTour teams sponsored by Specialized - bikes have white S-Works decals on the down tube and Specialized decals on the fork, which Specialized openly admit to giving maximum exposure during a race.
While riding for Quick-Step Floors last season, Marcel Kittel became the first rider to win a stage at a Grand Tour on disc brakes and the Belgian team's sprinter for this year has continued the trend.
In conjunction with the new frameset, Specialized also launched the new S-Works Aerofly 2 handlebars, which are designed to work in conjunction with the frame's proprietary stem.
Alongside the Specialized frameset and cockpit, Gaviria runs an S-Works Romin Evo saddle and 26mm S-Works Turbo tubular tyres. Specialized's wheel brand Roval also provide the Belgian team with carbon wheels with Gaviria's bike equipped with Roval CLX 64s.
Paired with the black and blue frameset is full Shimano Dura-Ace R9170 electronic groupset. Gaviria opts for standard gearing of 53/39 chainrings, an 11-28 cassette and uses 172.5mm cranks.
