too short a bike...(2 posts)

too short a bike...mattcrout

my problem is that my bike is a little short for me. i'm a little odd in that i have very long legs (37inch inseam) but i'm only 6'3" so my upperbody is short. so, when i get on bikes that are tall enough for my legs, they are too long, and bikes that are the right length, are too short for my legs. that is my current situation, good length, but too short. i konw i can get a higher seat post, but then the handelbars are too low. i have a quill stem, and it's up as high as it can go. also i'm afraid if i get a higher seatpost, it will put me too far back on the rear wheel without enough weight over the front wheel. do they make seatposts that are more forward (opposite of a setback seatpost) what can i do about the low handelbars? any suggestions would be great. oh and i can't afford a new bike. thanks!

Is that inseam a "cycling inseam" to firm crotch contact in bare feet, or a pants inseam? If it's a cycling inseam, you need about a 64-65cm (c-t)frame. A saddle height, measured from the center of the bottom bracket to the top of the saddle and parallel to the seat tube, would also be helpful.

You didn't mention the frame size that you're trying to ride. If it's too small, you may be beyond help.

You didn't mention if your bike has a quill-type stem or the new threadless stem. If it's a quill type, you can get a stem with a longer quill to help raise the bars. If it's threadless, more stem rise is the only answer.

A large rider should be able to handle a 10cm (4 inch) vertical difference between the bars and top of the saddle. What difference do you have now and what are you trying to achieve? Measure from the floor to the top of the saddle and from the floor to the top of the bars, and take the difference.

Although a 37 inch of 94cm inseam is long, it's not outrageous for your height. I'm 8 inches shorter and my legs are 4-3/8" shorter. My height to leg length ratio is only slightly less than yours and I fit fine on stock frames.
