The other day I went to www.wrenchscience.com and did the fit thing. Just checking to see if my bikes are set up correctly.
Everything calculated to my bike's actual measurements except the "recommended saddle height". It came up 7.5 cm shorter than what my saddles are set at. Can this be right?
I originally set the saddle height using the "seated on saddle-pedal at bottom-heel on pedal" method. If I lowered my saddle this measurement would be way off. :confused:
Got any ideas to clear this up?

Does anyone know why wrenchscience.com doesn't give any measurements for handlebar height either from top tube or in relation to saddle height?
Thanks.

Well, as previously mentioned on this forum, the sizing formulas are just an approximation. In the end many times you just have to deviate and "go with what feels good to you". Hope this helps.

Wrench Science fit numbers are usually pretty close. Double check all the fit measurements you made and make sure they're inputted correctly. Also, Wrench Science does make a handlebar height recommnedation, in relation to the height of the saddle (rather than height above the top tube).
Put your bike on a trainer and wear your usual shorts and shoes; have a friend oberve you from the rear. If your hips are not rocking and you fell comfortable...don't sweat it!
