Bravo au champion et à son équipe. Le record de l'heure n'est pas battu aujourd'hui, il le sera bientôt. Merci Dominique pour le partage de ces belles images et vive les propulsions humaines ...

Merci à vous d'apprécier nos reportages vidéo.

Beautiful track record (no pun intended ;) and gorgeous bicycle! I’d love to ride it sometime! Maybe I should consider building one? :)

[@deezynar]

57 miles in one hour. Impressive!

[@cbpaton53]

... fantastic, well done 👏

[@aaronvanhoucke2065]

Ar you in there Backwords? And why?

[@reinach77]

Est ce que il existe une vidéo en français ou anglais qui explique les choix technologiques pour le record ?

[@wasbigman123456]

Bonjour, félicitation pour cette tentative. Est ce que francesco roule en boyau ou j'ai mal vu ? (A 14:45)

[@Russo_Speedbike]

@Alcange oui, boyaux

@@Russo_Speedbike Bonjour Francesco, pourquoi vous n'utilisez pas des pneus tubeless qui ont un meilleur rendement ?

Any power numbers?

[@jcgosselin]

Francesco is a very strong amateur rider. I'm not sure his power can be published here...

[@casualguy393]

@@jcgosselin Is it top secret?

[@yohandsome]

If you estimate his CdA to be 0.07 (typical for recumbents with fairings) and CRR 0.03 at a system weight around 100 kg, to go at 92 kmh you need to output 342w: 259 w to overcome air resistance, 74 w rolling resistance and around 8w in drivetrain losses at 97.5% efficiency.
To average 100 kmh you'd need 424 watts, something a world class time trialist could possibly achieve ;)

[@jonathanz9889]

​@@yohandsome you forgot to mention your air density assumptions, you could achieve 100kmh without a world tour guy at high altitude

[@Heavywall70]

He has to crash to stop?

[@jcgosselin]

No but the felt it was easier and less risky than being catched by his team (which is the usual way).

Not for the claustrophobic!
