First post, so please bear with me.



I am looking for my first tri bike (used) and took everyone's advice and got a fitting. This was the first time I have ever attempted to get into the aero position. Based upon some flexibility limitations in my hip flexor (according to my fitter), being overweight, and having never ridden in this position before, I ended up with fit numbers outside the normal parameters.

The highlights are:

Saddle Height: 834 mm
Saddle Setback: -37mm
Arm pad stack: 773 mm
Arm pad reach: 463mm
Arm pad drop: -46mm
Frame stack: 631mm
Frame reach: 428mm

EDIT: 100mm stem, 172.5mm crank and a 155 mm specialized power comp saddle was used.

I am 6'1" with a 35'' inseam. I have approximately 210 lbs, down from 260 in the last year.

From what I've seen, the stack number is way out of whack based upon terrible flexibility. The fitter told me that with some trainer time and flexibility work over the winter I could get this number down.

So my question is, without a bike I cannot spend time on the trainer working on flexibility. Therefore, should I be looking for something that closely matches the reach numbers with as high of stack as possible and just work my way down over time?

Something like the 2014 Felt B series seems to have a higher frame stack (573 mm) and a narrow reach (436 mm) in size 58.

Thank you for anyone who takes the time to read this an reply. I greatly appreciate it!
