Top tube length
 

So i did a quick fit from competitive cyclist. I will have to go back and do the measurements again with my wife. For now however it has my top tube length at 77.1-77.5??? Can this be right? Right now I am riding on a 58cm bianchi but I am not finding any bikes with top tube length of 77.1??

Seat tube range c-c 55.9 - 56.4
Seat tube rance c-t 57.7-58.2
Top tube length 77.1 - 77.5
Stem Length 9.2 - 9.8
BB-Saddle Position 175.0 - 177.0
Saddle-Handlebar 43.7 - 44.3
Saddle Setback -8.5 - -8.1

Have somebody else measure next time.

Do you think perhaps you have a problem with the numbers you entered? Looks to me like you did the leg part correctly and completely screwed up the rest.

A 77 top tube is beyond preposterous. But such is the power of online calculators. We want to believe the result, right?

you're doing it wrong.

you must have done the sternum notch and/or torso length wrong.
what values did you put in? I believe that will answer the question.

This is what i inputed in inches. I just assumed my crude job would be a bit closer...I guess not


Measurements
-------------------------------------------
Inseam: 34
Trunk: 23
Forearm: 10
Arm: 21
Thigh: 11.5
Lower Leg: 23.5
Sternal Notch: 64
Total Body Height: 73

Check those numbers again. They are all over the place. Look at the pics they give for what they are looking for.

Also you can't really measure yourself. It is easy to be off about 2-3 inches without the help of someone else.

I think your sternal notch is somewhat high. That leaves 9in of room for your neck and head.

Fixed...albeit still off as I havent had someone else measure me. I was trying to be a bit more precise this time.
