Competitive Cyclist Fit Calculator Confused?
Figured I'd see what my recommended sizing was. I put my measurements in and it game me a top tube recommended length of 64 cm or so. I ride a 56cm right now so this must be way off. Heres the measurements it gave:
Competitive Eddy French
Seat tube range c-c 52.6 - 53.1 53.8 - 54.3 55.5 - 56.0
Seat tube range c-t 54.3 - 54.8 55.5 - 56.0 57.2 - 57.7
Top tube length 63.9 - 64.3 63.9 - 64.3 65.1 - 65.5
Stem Length 13.5 - 14.1 12.4 - 13.0 12.6 - 13.2
BB-Saddle Position 75.8 - 77.8 75.0 - 77.0 73.3 - 75.3
Saddle-Handlebar 63.7 - 64.3 64.5 - 65.1 66.2 - 66.8
Saddle Setback 3.3 - 3.7 4.5 - 4.9 4.0 - 4.4
Heres what i put in for measurements:
Gender M
Inseam 32 in
Trunk 41 in
Forearm 14 in
Arm 24 in
Thigh 22 in
Lower Leg 21 in
Sternal Notch 56.5 in
Total Body Height 71 in
Looking at picking up a Kilo TT frame and this threw me off.

Eddy fit is a more stretched out fitment AFAIK.
Lots of folks find the Competitive Fit to be ideal. But for those who find its aerodynamic emphasis to be overly aggressive and uncomfortable, the Eddy Fit is almost certain to be ideal for you. It's a position that reminds us of the way Eddy Merckx looked on his bike in the early 1970s, and it dates from well before Eddy's time and continued in the pro peloton well into the 1980s.
There is nothing "dated" about this style of riding. We all know that Eddy, Bernard, and Guiseppe were all very, very fast riders! Bike design has not, in fact, changed that radically since their time---only the look, the fashion, and the style of riding. The Eddy Fit is simply no longer the "fashion" among pros who keep pressing the envelope of comfort to create more efficiency and power.
The Eddy Fit emphasizes less saddle to bar drop. You will notice less exposed seat post on traditional frames and a lower saddle to bar ratio on all fits, including compact designs. Typically it requires a size up of about 2-3cm in frame size from what is today usually offered by in current aero professional look of today. But make no mistake about it, this fit will get you down the road with speed, efficiency, and power.
A few differences from the Competitive Fit in addition to a taller front end and less saddle/bar drop is a less craned neck and easier forward-looking position, slightly less weight on the hands and more on the saddle and pedals, and a knee position that usually moves a bit behind the spindle (rather than a knee-over-the-spindle position, thus adding a bit of power). Bikes set up for the Eddy Fit change their look only subtly in comparison to the Competitive Fit though the results are dramatic in terms of greater comfort. This fit is easier on the neck and shoulders but no less suited for racing or fast solo or club riding.
We adjust this fit by "sizing up" the frame and adjusting the stem lengths to create proper balance, proportion, and to maximize the frame's potential. This position lets you into the drops with less stress on the neck and back and so encourages you to go low into the bars for longer periods. The Eddy Fit typically features a saddle/bar drop of only a few centimeters.

here's mine, looks like your trunk is much larger than me.
Measurements
-------------------------------------------
Inseam: 32.75
Trunk: 27.5
Forearm: 13.5
Arm: 26.5
Thigh: 26
Lower Leg: 23
Sternal Notch: 60
Total Body Height: 71
The Competitive Fit (cm)
-------------------------------------------
Seat tube range c-c: 53.9 - 54.4
Seat tube range c-t: 55.5 - 56.0

just to add this is only a quick measure of myself attempting to follow the measurement guidelines with a tape measure and level so it may not be completely accurate.

yeah your trunk measurement is likely off. I'm 6'7 and you have a good 10+ inches on my trunk measurement.
edit: not to mention 41/71 means your torso, not including your head, is over half your body length. Good lucky buying shirts.

Now they look like this:

Seat tube range c-t 54.3 - 54.8 55.5 - 56.0 57.2 - 57.7

Saddle-Handlebar 52.8 - 53.4 53.6 - 54.2 55.3 - 55.9
Saddle Setback 3.3 - 3.7 4.5 - 4.9 4.0 - 4.4
So it seems i should be leaning towards a 53cm kilo frame or should i go with a 55cm?

I'd rather have a TT that's slightly too short, than too long. But you can always get a shorter stem if you go with the 55cm
