FIST Fitting advice (1)

Triathlon Forum
1

I recently had a FIST fitting, well happy with the final position, now I’ve had a few rides to adapt.
My stack and reach measurements ended up as 490 stack and 445 reach.
Trouble is my Tri bike, Kestrel Airfoil Pro, is a bit short on reach for me. I’m shorter legged, longer torso according to the fitter.
From the fit, I have my Adamo saddle set at 15mm in front of the BB.
I have had to use a 140mm stem, and have the tri pads forward of the h/bar to get the correct pad distance from the saddle. It Works ok, bit it has felt a fair bit twitchy at times.
Looking at the stack/reach charts for various bikes, not many are close to my stack/reach, in fact my Kestrel is probably the closest!
Any recommendations for a frame that will fit me better?
Many thanks

Yes, a 140 mm stem sounds long-ish, but you haven’t given enough info yet to really help answer:

Things like aerobar stack and reach play a role too. For example, if you’re riding low but using a high-rise aerobar means your frame has to be super-low.

Thanks for reply, I will read through the linked article later at home.

As for more info, if I knew how to post the PDF file I would add it here.

I am riding with 110mm of drop,
cockpit 820mm,
saddle height 715mm,
Extension length 385mm
saddle tip to armrest 470mm

I do recall the fitter saying maybe the older Cervelo P3’s were longer and lower, is there anywhere that info is available?
Thanks

Anyone have any ideas on what frames are out there that may fit me better?
Thanks
