I got 172.9 and the bike has 175. Will live with them for now and change to something smaller when I have some spare cash.
cheers

They say to start with 9.5% of your height and you won't go far wrong.
But where do they get 9.5% from?
If you consider the range of crank lengths commonly available (165mm to 175mm, or 10mm) and compare that to inside leg measurements (61cm to 94cm, or 330mm) , it's difficult to see any meaningful correlation.
If you trawl the web, you'll find plenty of crank-to-leg-length calculators, but never an explanation as to how they arrive at the number you multiply your measurements by.
All very scientific looking, but like much psuedo-science, they seem to be making the mistake of knowing the answer they want and tweaking the formula to produce it.

Yep. Mega difference for all the reasons above.

I'm 173cm with short legs (30" inside leg) and find 165s the best for me.
