Whats my approx frame size?James1
Aug 7, 2001 8:26 PM
I'm 6'3'' 34 inch inseam. Can you give me an idea of what size frame I should be looking for. (I know it varies by manufacturer) Just need a ballpark idea of where to start. I'm guessing 62cm??

TIA

Check your inseam again, 34 inches sounds short for 6-3. I'm 6-0 and have a 34.25 inseam, I'm sized for a 58 or 59, depending on the manufacturer...

Inseam is definitely 34. I have a hard time getting fit correctly I think because of this.

I was on a 61cm C-C (w/ 60cm TT). Now on a 60cm OCLV with 58.1cm TT. New bike fits ME much better. Bars are way lower, so back is flat. Stretched out, but not S T R E T C H E D O U T !!. Get properly sized on a fitting machine thingy.

Both my "road" bikes are 25" c-c frames, which corresponds to 63.5 cm c-c. some people think that is too big for me, but I disagree. My saddle is at least 3" above the top tube on both bikes. The specs are as follows:

touring bike:
25" frame
120mm stem (technomic-sits higher)
Nitto 135 radonneur bars
175mm cranks

road bike:
25" frame
100mm stem (common height, classic "7" style)
46cm Cinelli bars
172.5 cranks
both bikes use look pedals

I ride with my knees over the pedals, and they have a bit of bend, even at full stretch. The saddle (brooks B72)sits a bit farther forward on my tourer, and I still stretch out a bit more on that bike, but it works for me. Saddle is about even with the bars. Standover clearance on this bike is less than 1".

The road bike sits a bit lower, partly due to smaller tires. On this bike, my saddle sits nearly all the way back (brooks professional). I keep this saddle about 2" higher than the bars.

For you, I would say start at the 23"/62 cm size, and go up. I doubt that a 27"/68cm size will fit you, and you will also find that a lot of really nice frames are not available in your size, even by special order.

According to your inseam you'd go for a 58 cm frame probably. But your build is atypical. So you might want to consider a custom frame. You're going to have a tough time getting a proper top tube length and seat tube size in a stock frame. One idea would be to check out Marinoni. They'll build custom for just about any bike in their line.
