You can stiffen up every interface between bike and rider, but any improvement in output is miniscule compared to the gains made by training the 'engine'. It's a money pit. Just look at the results in the recent Planet-X Old Skool series. Even with the technological advances that can surreptitiously be added to bicycles fit for the Merckx hour or whatfuckingever, no-one's coming close to the records set by athletes who worked a whole lot harder, back in the days of 3-day weeks, square tapers, box rims, and shit.
Q factor's only an issue for the pigeon toed.
