Bike Fitting Problems Longish

[hid558]

Don't know if this has been discussed before, but how do I know if we have a long or short torso based on bike measurements. I have a Cannondale Synapse 4 with Sram rival size 44 cm. She is cute and everything but since I bought her I have trying to adjust her in many different ways and don't seem to get it right. It comes with a 70 mm stem I have changed it to 90 mm and 100 mm. I have changed to seat post to layback. I have upped the seat and lowered it. I have been fitted but really don't trust the fitting guys here and don't think there is anybody who could do a good fitting here. I live in Puerto Rico. These are my measurement:

inseam 69.85 cm = 27.5 inches
trunk 50
forearm 32
arm 60
thigh 54
lower leg 49
sternal notch 125
total body height 149 = 4' 11"

I don't seem to just feel right in the bike. I am now feeling pain in the shoulders. My wrist hurt if I bend to much my hands. I don't know if maybe the bike is to small for me I sometimes feels cramped and have to like move back on the seat. Maybe I need a unisex frame instead of WSD. Can somebody help me. I really like riding, and I have improved my riding skills. But I know I am really comfortable on the bike. Don't know if I should sell my bike and try getting another. I don't have any way of trying bikes out here. I just have to buy any brand based on measurements and geometry. Can any of you gals who know about bike measurements and how to look for a bike based on geometry help me. Please somebody help!

Is there any way you could post a photo of yourself on your bike from the side, whether on a bike trainer or even next to a wall if you can't get an action shot, anything is better than nothing. That might help us help you!

Since you're quite petite, it doesn't sound like a 44 cm bike is too small for you, on the surface, but I know there are gals on here that ride larger bikes for their height than I do since everyone is proportioned differently. Just a data point for you: I am just a hair under 5'2" and take about a 46 cm in a road bike. I need WSD as I have long femurs and end up using a setback seatpost to get the proper knee over pedal-spindle position, so I can't deal with a long top tube at all.

Post a picture if you can, feet at 3 and 9 o'clock is best.

Just as a comparison - I'm 5'4" and have a 28" inseam. I have a long torso and short legs. Since I'm 5" taller than you and we have almost the same inseam, I'm going to say that you have long legs and a shorter torso - or more typically female dimensions. I would think that in general a WSD would be right for you and a 44cm is probably pretty good.

That said, as you have found, there are tons of tweaks that can be made to a frame to get the fit right...so even if your base frame is correct, it is possible to be super uncomfortable if your fit wasn't well done.

Maybe I need a unisex frame instead of WSD.

I was once told by a bike fitter that if a woman is evenly proportioned that a unisex bike would probably fit better. I once rode a women's specific bike and it was too small even though I was measured for the correct size. I have what would be considered a long torso for a woman but am equally proportioned if that makes sense.

Not all WSD will fit the same. Try a different brand and even some unisex bikes to see which one feels more comfortable to you. If you can't replicate the feel of the fit on your bike by trying a different stem length, seatpost, etc., you may want to consider a different bike altogether.

How do I know if I have a long or short torso? Based on measurements what should I look at?

[Irulan]

one way to tell is to be aware of how most clothes fit you. Is your inseam average, longer or shorter than average? You should know by how tops fit if you are long waisted or not. A tailor should be able to tell you also.

How do I know if I have a long or short torso?

Look in the mirror. Do you look "leggy" or do you have a lowered waistline?

As a kid, I found out I had a long torso when I was measured for a leotard. I have to buy long torso swimsuits as well.

I'm with the photo request. One of you in the drops, and one on the bar, looking straight ahead. I'm thinking this is a seat thing, but it would be great to see you on it.

Heres me on the bike!
