Hi pals, I have an odd body type. I have a long torso, long arms, long femur, and short tibia. Are there any extra considerations that I should make over the "standard" bike fit to accommodate my body type? I follow a few general tips and rules but really want to fine tune this to my body type.

Sorry, can this be moved to Bike Fit thread? Didn't see that until now

Yes, a bike can be set up for you.

With absolutely no details, no possible way of providing anything further. But it can be done.

Panza

Haha, sorry. What details should I provide? I'll do my best to gather what's needed.

It's virtually impossible to size a person when I have no idea if the measurements are correct. Frame sizing will be an issue (I get the feeling you already have a bike, somehow, and are trying to make it work...just a hunch), but generally a longer torso will require a longer stem. Handle bar reach, for your longer arms,. but a long femur needs to be addressed, possibly with a slightly longer set of cranks...there are just too many variables to really give you specifics.

My suggestion is to find a fitter who can work with you. People with odd body shapes can be interesting to set up, but if you are really out of the bell curve sometimes a custom frame is necessary, but not too often. Usually it requires different parts to make it work.

SO, if you are looking for specific measurement, it's impossible to do in this format. You need to be measured by a qualified fitter.

How long are tibia supposed to be?

This ^^^
I wish I had a nickel for every rider that thought he had a 'special' body. Reality is, very few cyclists have ordinary proportions whatever that is.
So we all need a good fitting. Fittings are as much art as science anyway...ordinary proportion or not. This is because the aggressiveness of the fit needs to match the flexibility and even riding preference. Faster and more aggressive riders well tend to prefer a more aggressive fit because of higher pedal forces that will neutralize a more forward leaning position on the bike. Even that isn't an absolute.

I'd look for a frame that's long and low, with a short head tube to allow your long arms enough room to get you low.

The OP was talking about his femur...average is about 27% of your height (femur is the longest and strongest bone in the body). Leg length to use for bike measuring, from bottom of foot (without a shoe) to your sit bones is about 48% of your total height.

When we measure for a frame we measure the leg length and the total height. then there is a calculation done (body percentage leg to height) which translates into a top tube length.

If a person really gets out of the "bell curve" it requires some additional finagling, then we can look at details like femur length, etc. But it all has to be looked at as a percentage since, obviously, a person 6'6" is going to have different actual lengths than a person 5'5".

dtrain

No, he specifically said that he had a short tibia. I'm just teasing him anyway.

Elvo

You know what they say about girls with short tibias

Panza

They like a long femur

I had been doing some research and people with my inseam and height opt for longer stems which seems like a very reasonable solution to accommodate.
