So my basic quandary is this. I was interested in getting a surly steamroller or a mercier kilo wt, but it seems like the ideal size for me is between the 53cm and the 56cm. In most bikes, the 54 or a 55 is going to be best.

Here are my measurements:
Measurements
-------------------------------------------
Inseam: 81
Trunk: 65
Forearm: 36
Arm: 65
Thigh: 58
Lower Leg: 52
Sternal Notch: 143
Total Body Height: 174


The Competitive Fit (cm)
-------------------------------------------
Seat tube range c-c: 52.4 - 52.9
Seat tube range c-t: 54.1 - 54.6
Top tube length: 55.1 - 55.5
Stem Length: 11.2 - 11.8
BB-Saddle Position: 69.3 - 71.3
Saddle-Handlebar: 53.8 - 54.4
Saddle Setback: 4.7 - 5.1


The Eddy Fit (cm)
-------------------------------------------
Seat tube range c-c: 53.6 - 54.1
Seat tube range c-t: 55.3 - 55.8
Top tube length: 55.1 - 55.5
Stem Length: 10.1 - 10.7
BB-Saddle Position: 68.5 - 70.5
Saddle-Handlebar: 54.6 - 55.2
Saddle Setback: 5.9 - 6.3

and the steamroller and wt measurements for the 2 sizes are:
53cm 56cm
seat tube (c-t): 53.0 56.0
top tube: 54.7 56.8

so, where most bikes have a 54 or a 55 option, this bike does not and that seems to be where my ideal size would be. I know fit is somewhat of a personal thing, but if it were you, would you look for another bike that has a better size (the dawes sst al in 54 looks almost perfect) or would you just try to pick the closest one? In this case, I am assuming the 53 should be a better fit, correct?

opinions?

thanks in advance for your non-snarky responses. I know fit questions get old, but this has me kind of stumped. I would go to a shop, but no one near me has the steamroller for me to try out.

If you are between sizes it is almost always better to go the size down. A too small bike can be compensated for somewhat by having a longer stem and showing more seatpost.

Get the 53.

It's easier to make a small bike "fit bigger" than it is to make a big bike "fit smaller".
