I am going through the same thing now. That is a lot of bikes. After questioning if I should retro-fit my bike that's not my ideal frame size now, I decided to do the professional fit route.
I plan to do some traveling to look out of town at shops, and think while I am there, I'll get even another op. Plus, I have done my own reading and measuring at home myself best I can. And, seeking some help from bike pals locally... plus my friends here at TE.
It may sound like overkill, but "one" $ mess of a non-fitting frame is enough for me. I figure the $, time, travel, etc. I spend getting fitting help is nothing compared to the cost of a different bike that still doesn't fit. And, as you mentioned, I have pain issues too... that one is hard to put a price on it.
I would also suggest getting some medical advice on the back. If any way possible, find someone who knows cycling. Be it a sports med doc, PT, etc. I went through this recently as well and it was a help.
Add all that $ up and the cost of a fit in notta! Plus, if I do decide to buy the entire bike at the lbs I paid for the fit, they will credit it towards the bike.
Good Luck!![]()
