i'm 6'4". i prefer a smaller frame, though i ride a variety of sizes. i try to keep my combined top tube length and stem length around 70 cm...

my most comfortable bike is my iro jamie roy fixie. 59 c-t, but the top tube is slightly compact. 58 c-c top tube, 120mm stem, fairly deep (180mm) modolo track bars.

my guerciotti sl (geared) is a 58 c-c seat tube and 58 c-c top tube with a 120mm stem and 150mm deep itm track bars.

my bianchi pista is a 58 c-c seat tube and 57 c-c top tube, with a 130mm 3ttt pista stem with a very negative drop and super deep (200mm), and sexy i might add, 3ttt pista bars.

my ross (geared) and my peugeot (fixed) are 63 c-c, but i have more of an upright position on these due to my inverted and rotated cruiser bars on them. they droop down and swoop back. 120mm stem on the peugeot, and a too short 100 mm stem on the ross due to not being able to find a 120 length stem with a .883 quill...

how's that for too much information? i'm not working late or bored or anything of the sort... *ahem*
