I know this sounds like a Newbie kind of question...BUT.....

Have a few questions about my first bike, and what you think about the size. It's a newer one, an 05 Trek 1000SL. I've ridden, maybe 300 miles this year on it (not alot) but I did do a 2 day, 150 mile ride a little while ago. While the size doesn't bother me, do you think it's too small? I'm 6'1", and have about a 32" inseam. Top tube (center to center) measures *about 58cm, seat tube, c-c measures 54cm. Standover is 32.25"

Too small? Where do you typically determine the "XXcm" sizing dimension from? Seat tube?

I have 2 other road bikes (vintage), wonder if one of them may fit better.

1984 LeTour - 34" Standover (too big IMO), top tube c-c 57cm, seat tube c-c 62cm

198? Cilo - 31.75" standover, Top tube c-c 56cm, seat tube c-c 56cm.

The Cilo is kind of similar dimensionally to the Trek, but the Geometry is VERY different, and thus *feels* smaller.


I do know that I have been starting to get some knee pain, which could be my seat height, of poor form on long rides...

What do you think?
