I don’t know if “scam” is too strong of a word but here’s what I wonder…
Let’s say I seek out the foremost fit specialist in the country and have him fit me to my bike and pay him the money.
Then the next day I go to another highly regarded fit guru and try to buy a fit. Does this guy tell me…
“can’t take your money, this fit is bang on, it’s just perfect”? I’m not sure that he will.
I’ve done this a few times. Basically said, “Hey look, there’s not much I think we’re going to change here. I’m happy to tinker on the fit bike and see if we can optimize but, otherwise, thanks for coming in and have a nice day.” No charge.
