There's several ways you could read it.Are those times from training rides on Strava or in-stage times?
Either way, it shows that Pogacar's time isn't as unbelievable as some make out given this time was a short TT that Pog could go all out, and not at the end of a long stage with more racing to follow
I regard Froome & Nibali as 2 of the worst dopers of the last 15 years, albeit using drugs which have so far proven undetectable. That Pogacar has beaten their bests by 10 & 30 seconds respectively casts a huge shadow over Pogacar's ride last night. Remember that's at least the 3rd climb this Tour which he (and other riders) have smashed the previous records. This year's peleton is clearly on some very good juice.
On the other hand, the times set by Nibali, Froome & Aru were probably at the end of a 150+km stage, whereas Pogacar was starting relatively fresh with only 20km of flat TT behind him at the start of the climb.
