I’m not impressed by the quality of the survey, and feel that it lacks initial input from cyclists .
E.g. do you consider yourself fast - I would consider myself fast if I had several race wins/ season ( I don’t these days) .others may define this as averaging x mph, others as y mph
What is your average speed ? On a main road, on tracks, in towns? Too many variables to be valid
In particular - the aero position question. Is the designer aware that tri bars are only allowed in certain events, or that they and other options are highly dangerous in windy conditions?
The key error for me is in surveying “ cyclists”. It’s like mixing marathon runners with people walking to the pub. My view of cycling is, I know, very different from many others, as theirs are from mine.
