Yes, you are too tall for 51cm frame. Try next size larger (54cm).

So the size 54 is the minimum size for me?
That would be a shame since the deal was for a Size 51…

Based on your measurements, 54cm frame should be closer to optimum fit without excessive stem/crank-length modifications. Plus, it will generally give you wider range of fitting options.
I’d say there is a very high percentage chance the 51 won’t fit and ride well. It may fit at the end of the extreme but at 5’11.25", I don’t think its the optimum size; and a Competitive Cyclist calculation really wont tell us much.

Are the measurements i gave under “**My Measurements” **enough or are there more variables as well that needs to be taken into account?
I have the same inseam at 840 but seat at 755mm, but extension at peak a bit longer than you. I ride a 51
….But I am only 5’8.5"….so you are about 2.5" or 8cm taller but all in the torso, I was in between sizes but the 51 was the pick for shorter head tube. I really don’t think 51 would work for you….Unless you ride really, really slack.

If you have a TT bike already you could measure that then look at the P5 fit chart.
As it happens my wife has the same proportions and would struggle to get on the 51 as her bars are so low the lowest setting of the Aduro bar would be too high.
If you are not so low the 54 would likely be a better size for you, but it’s not a given.
