I seem to remember that Ed Coyle measured it at that value too, at UT, but the Tour value is more impressive as he would have been lighter and more tired.Idk what Armstrong's weight was but I remember him saying that he was doing 500W for 30min on Col de la Madonne pre Tour (I guess any Tour he won).
Speaking about Lance, I’d like to know how he feels about Pogacar. I think him, Hincapie and Bryuneel are either laughing their a…s off or are seething with rage
