Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

What size frame?

I have short legs (28 inch inseam) with a longer upper body. How do I choose a road frame size? I am 5' 8" and my friend is 6' 1". We are the same height when we are sitting down.

Thanks,
Ian

here's a link to DIY fit kit. It's hard to tell what size frame you need just by your inseam. The top tube length is really more important. 28" inseam would probably be about a 47cm seat tube, but obviously you need a really long top tube. not sure how much you want to spend. If I had the money I'd buy a Torelli for a bike with a longer top tube compared to seat tube, but there are many more options than that. http://www.torelli.com/index.html . and no I don't work for torelli

Cycling inseam is measured from the floor to saddle-like crotch contact in bare feet. It will be quite a bit longer than pants inseam. Take an accurate measurement and post the results.

I'm the opposite, at 5'-6.5 inches tall, with an 83cm (32-5/8") cycling inseam. I ride a 51cm LOOK 585. You might be able ride a 51cm, but more likely you'd need a 49cm to fit your legs. Those with a long torso should use long reach bars and not be concerned if a 120-130mm stem length is required. Pros use up to 140mm and think nothing of it, but here at BF it seems like people think something is wrong with the fit of a small frame requiring a 130mm stem.

When comparing frames, look at the head tube length for vertical sizing and the TT length with the seat tube angle to determine reach. Steeper STAs make the reach longer, by about 8mm per degree in your frame size range.
