So how do you define a "screwed up fit"? At Serotta fit school they would measure range of motion at the hip, then apply that to the bike position. That's what I call a static position, the upper body in that model doesn't move, so the torso angle is fixed and the hip angle is determined by just the movement of the knee. So being beyond that limit (by Serotta Fit School's definition) would be a bad fit. Here's the thing, any time my hip angle is that tight, my body weight is over the pedal, and there's upper body movement as I leverage my body weight on the pedal. So, at the top of the pedal stroke my torso is higher, so in the dynamic case I'm not outside of my range of motion.

That's how it appears to be where body weight distribution is concerned.

You will find it in number 5.

Interestingly written article, point 5 is fine but I find point number 6 to be most enlightening. Neither author's name nor support for any claims are mentioned, and grammar makes it hard to understand what he is trying to say at times.

5. Unweighting upper body from the handlebar


MYTH
“You should still be able to play the piano when riding” Bernard Hinault
A rider’s position is best determined by having little or no body weight on the handlebars.
While I did spend part of September riding from piano to piano (there were 60 pianos put out on the streets of Boston) I find I can't play and ride at the same time. even if I could, the sheer weight of the piano would really slow me down going up hills...

Quote:
Hinault’s comment is open to interpretation in regards to handlebar position. Perhaps Hinault was gifted with exceptional core strength, and this, as such, is arguably the most appropriate takeaway from his quote.
Seems like all of my clients are also gifted with exceptional core strength


Quote:
Some bike fitters suggest that by sitting further back, it shifts your centre of gravity, placing more weight onto the seat, and less onto the handlebars
Well, changing fore/aft of the saddle does move the rider's center of gravity, but assuming the rider's position doesn't change, it doesn't move their center of gravity in relation to the saddle. it moves their center of gravity in relation to the pedals. You know, the two things attached to the cranks...

There's also that bit about power pedals, and a web site listed as bikepowerpedals.com - no such thing... I couldn't figure out how they get vector data from what was there.

To be fair, most shops put their staff under favorable lighting, to put it mildly. If I'm honest, they just plain lie. My own shop claims to have a pro rider on staff...

This thread has turned into a very meta example of why fitting sucks

That being said I've heard a bit of what doctors have to say about each other behind closed doors....

I was being somewhat facetious when I asked that question Ed. His bio on the Bikepro page doesn't establish much in the way of credentials and he certainly does have a lot to say without much to explain the why of his statements.
