Hello all,
I've read all the fit articles here and attempting to do a FIST setup on myself. I'm wondering if I could get some input on my current fit. Here are the specs:
64 inch Height (me, not the bike)
Size 51 (700c) Cervelo P3 Aluminum
140mm cranks
ISM PN 1.1 saddle
Felt Bayonet 3 Aluminum Aerobar
3T ski bend extensions
10mm pedestal spacer
90mm 0 rise stem (i.e. -13 degree)
580mm Pad stack
520mm Pad reach
13.5 cm Pad drop
72cm seat height (measured from bb to 4cm behind nose)
Here is the current fit (more on the saga and how I got here below):
Hip angle not shown, but comes out to 105 degrees, so not exceptionally low, but in the range.
Here is where I was starting from, with a really low stack Easton carbon integrated bar and 165 mm cranks.
I was really cramped at the top of the pedal stroke and the Aerobar had almost no adjustment available. So... I changed everything. All at the same time. New 140mm cranks, new Felt Aerobar, new saddle, longer stem. I know it wasn't a great idea to change every contact point at once, but here we are.
This was my first attempt at getting the fit right:
Felt pretty good, but measuring the angles said that I was a little too low (140 degree knee angle) and a little cramped in the reach (179 degree shoulder angle).
Tried moving elbows forward:
Then tried moving butt backwards:
Decided to move seat up and back and after a little tweaking, came up with the position at the top.
Here is the video of the current position:

Here are some of my questions:
1) I understand the idea behind the FIST protocol, but don't see anything about optimum seat angle, so I really don't know how far forward or back I should be sitting?
2) Knee angle seems ok, and I've always ridden with toes pointing down a bit, but maybe something needs to change?
3) I understand the idea behind pelvic rotation, but don't know how to recognize it, or what fit changes would help.
4) Feel free to coach me on shrugging and head position. Below is a final photo where I tried a lot than normal head position, but where I could still see ahead of me.
