I borrowed this off a friend of mine to race today, i’m wondering if I need a longer top tube, my road bike is 58.7, this tt is 55.7. I suspectthe seat’s too high, I just kind of guessed it into place before the start. My drop from the saddle top to top of aero bars is 4 inches. Any observations would be helpful.

It looks fine. If anything, the FIST police will say that you are a little too extended in the arms and your top tube/stem ought to be a little shorter. The real question you should ask is this–how did I feel when I was going hard? Was it stable? If you felt fine then you don’t need to worry about whether the Top tube seems 1 or 2 cm too long. It just doesn’t matter that much and your body will adapt.

What makes the shoulders drop more? There’s no more stacers left to remove yet my shoulders seem pretty high.
I’m guessing that is the correct frame size at least.
Odd that for someone who ride what is usually the largest road frame at a 60 would have to go down two from the top in most of the TT frames to get enough drop.
I doubt this setup would be uci legal is the other fly in the ointment
Seems to be the correct frame size.
Turn the stem upside down to get the bar lower.

Frame size (as in advertised seat tube height) is meaningless when comparing bikes of differing geometries. There are likely to be TT bikes out there that fit you properly in a size 58.
If the stem on that bike is already turned downward. Then you can search for a different aerobar that sits lower.
Why do you say it’s probably not UCI legal?

The nose of the seat sits about an inch back from the center of the BB, I’d have to slide it back almost another inch, but there’s enough room to do that. I had a 56 cervelo that I could just barely get to pass with the seat all the way back on the rails. I prefer to be more forward as I’m not all that agile.
OK, well if UCI legal is your goal then move that seat back to the limit and reconsider the cockpit then.
At that point your arms will be more stretched out forward and your hip angle will have increased…after doing this, talk of getting lower in the front end may be meaningless.

I’d rather have a bike that will meet the spec when I do a race that requires it (not too often) and ride more forward for the rest of the time, I just want the option and I think I will make it with most 56’s

Sure, It should only take an additional stem. To set your bike up from one to the other you can move the seat, change stems, perhaps change the stack by moving spacers above/below. (this assumes a new bike that lets you leave some more steerer on).
Thanks, I think that will work then, I can find some entry level sort of TT bike in a 56, I’m not any speed demon
