I have a fit question on the IA-16. I can't seem to decide if the stack and reach will fit me or not. My current fit coordinates (from a Retul fit) are:
BB to top of pad 713mm
BB horizontal to back of the pad 436mm
Frame stack 564mm
Frame reach 443mm
Tip of saddle reach 437mm
Arm pad drop -39mm
Seat tube angle 80degrees
(I have other coordinates that I don't know if would help or not)
It looks like the IA 16 58cm would fit me, but I'm not sure. I'll have to travel to find a felt dealer who deals in TT bikes, so before I go on a trip, I'd like to be sure (or reasonably sure).
Those numbers aren't right. If you'd like you can email me or PM me you fit data and I can take a better look. You should have body geometry measurements and hopefully some pictures as well.
That armpad drop is suspect for someone your size (may be a bad fit) and the frame stack to pad stack shows 15 cm. For reference, we use a Profile Design Prosvet base bar and T2+ extensions on our fit bike (Retul Muve), as well as a 90 mm stem pitched at -7 degrees. The delta between the armpad stack and frame stack is around 11 cm for our configuration - a full 4 cm of difference between what you fit records.
I'm not saying you definitely got a crappy fit, I'm just saying there are a few warning signs from the fit coordinates you've provided.
