I just don't get it beaverstuff... that is amazing. You're like an ostrich (no offense)...

I'm 6'3.5" and have a 93.5 cm standover (just measures) (that's almost 37") But the boys hand lower than that obviously.

62 is my max as they tend to have stantovers around 34.5" (35" on my 62cm track bike) yes technically that is 2.5" but don't forget the boys. I can ride 62cm frames with a vintage campy 180mm seatpost without being near the max insertion... your seat height should be 10cm below your inseam for a starting point which for me is about 83.5cm... I find this rule of thumb works for me in general give or take a cm or two.

More recently I have been enjoying the fit of a 60-61cm frame! Believe it or not I am running a campy post (at max height) on a 60.5 (c-c) gazelle and it is very comfy (i have very long arms so the drop ain't bad)... I attributed comfort with drop to physical fitness also (of which I am in poor shape).

On a 69cm frame I would imagine the standover exceeds you standover. SO how is this possible given your claimed height and standover?

Hear are a few thoughts. Have you ever had a professional fitting? They know what they are talking about and if you tell your fitter "I will not be buying a bike from you period" and just pay for the fit they won't try and fit you onto a bike that is too small.

Last week we had a monster in the shop (probably at least 6'6") and the fitter was complaining that he was pointing his toes like crazy which made it difficult to get the seat height right. Well one should ask why he is pointing his toes and I will venture that because 175mm is the maximum standard crank size, our fitter was using that length to fit this fellow on a bike. STANDARD CRANK SIZES ARE TOO SHORT FOR US! Period. I like 180mm but also have a set of 185mm cranks. I enthusiastically you to encourage the purcahse of longer cranks... if money is an issue watch ebay 180mm TA pro-5-vis cranks come up all the time and can be had for under $100 and provide unlimited gearing options. I know because my room mate and myself has each purchased a set this year and I have seen many sets go simultaneously. This will activate more muscles in your upper leg which will cause you not to point your toes so much. This is also the reason I think my room mate tends to run his seatposts quite high (he has many bikes with 170mm cranks and toe clips that are short). Which brings me to my next point. If you run clipless slam your cleats to the back or even consider having your shoes modified so they can be mounted further back. If will feel strange at first (and so will longer cranks) but that is because your legs are used to being squeezed on to average size person parts. If you run clips make sure they are XL or don't run clips at all. Get that ball slightly ahead of the axle and try to push down with a flat rigid foot instead of pointing your does. Cycling shoes will help as they have rigid soles.

Those are my thoughts.... you and I are essentially the same size based on just height and your standover measure.

P.S.

My room mate is 6'5" and finds his 65cm (35 3/4" standover) to be a perfect fit.
