My guess would be that they are not using the bike classification. But I guess you can test that pretty easily by changing the bike type and seeing if the wattage numbers changeI guess the thing I would like to know if strava works out power by sample aggregation of bike name categorization. I guess then they can work out averages from other peoples power meters. I do think the technology is very clever. It also helps I guess to have a popular bike that everyone loves like a Trek Madone or a Cruzbike Vendetta.
I will change it to a v18... guess no one ever made a V18My guess would be that they are not using the bike classification. But I guess you can test that pretty easily by changing the bike type and seeing if the wattage numbers change
