Hi All
I'm looking at a 2nd hand Guru Praemio with a 62cm frame. I'm about 183-184cm.
I have taken if for a test cycle and; can stand over the cross bar and when lifting the bike into my crotch get a couple of inches clearance under the wheels, have a good 6" of saddle stem showing with comfortable leg position, handle bars are slightly lower then the saddle, do not feel stretched out at all.
The bike feels high, but I do prefer a large frame rather than feeling a bit bunched up. It is more frame than seat and handle bar stem extension though!
Does this seem sensible to go for?
Many thanks in advance for any advice.

A really good basic rule of thumb is that there should be more seat post showing than there is head tube.
Super common to buy a bike too big.

Thanks for reminding me of that rule! I remember that the rule in the '70s and '80s was that seat posts and head tubes should be approximately equal in length. In any event, you'll probably agree that that rule of thumb is unreliable with sloping top tubes. Also unreliable with very large and very small frames. Finally, the fit depends on whether the bike is to be used for racing or casual riding or something between those extremes.

you are right!
