Those posting power figures for Wiggo compare for yourselves and make your own judgements.
Make your own judgement as I suggested, LS. You seem to be missing the point of that list, nobody made more than 400W up final climbs before 1990 whatever their size or weight.
Yes I think the 481W for Martin is suspicious, Aracer. Boardman had a significantly lower power:weight ratio using your own figures so less suspicious. There’s something I can see with my own eyes about Boardman’s performance, an aero advantage I can’t quantify that makes it impossible to compare his performance with any other rider before or after except Obree. I don’t know.
