Tour de France leader Tadej Pogačar has brushed off a query into the use of carbon monoxide rebreathers, a device reportedly employed by some WorldTour teams as a measurement tool for altitude training.

On Friday, Escape Collective reported that UAE Team Emirates, Visma-Lease a Bike and Israel-Premier Tech have been using carbon monoxide rebreathers but did not specify which riders are using them.
