With a change in team, the Italian rider also has a new S-Works Tarmac SL6 in a size 58. And he’s running the yet-to-be-launched dual-sided Specialized power meter on his 172.5mm cranks.
We initially spotted the Specialized Powermeter on Peter Sagan’s bike, but the whole Bora squad is using the unitsColin Levitch / Immediate Media
Oss’s new bike is equipped with a full Shimano Dura-Ace R9150 drivetrain, complete with 53-39T chainrings at the front and a Dura-Ace 11-28T cassette at the back.
At the front, the entire Bora-Hansgrohe team are running the burly PRO Vibe Sprint stems and Oss’s bike features 420mm PRO Vibe bars wrapped in Supacaz Super Sticky Kush bar tape.
At the back, atop the new D-shaped seatpost used in the new Tarmacs is an S-Works Romin Evo saddle.
K-Edge features heavy on the Italian’s bikeColin Levitch / Immediate Media
K-Edge features heavy around Oss’s bike with a Race Mount for his Wahoo Elemnt Bolt, as well as a chain catcher and GoPro mount, which the mechanic told us was only for the training rides and wouldn’t be used during the race.
