+1 for NOT KOPS

I when I tried KOPS and and Obscuring axle method, I got a scrunched up position with too much weight forward.

Then I read http://www.peterwhitecycles.com/fitting.htm and http://www.stevehoggbikefitting.com/blog/.

They suggest the balance method to determine saddle setback and subsequently stem length. I am now behind kops and have a longer stem. Also note that the handlebars you use and the tilt you use them can affect reach to the hoods by as much as 3cm. So right there, the obscuring axle method is screwed already.

I have followed a lot of the advice from the blog and it has solved all the problems I had. Especially shoe insoles, shims, varus shims, cleat position, crank length etc. It took me a few months of testing, but my position now is awesomely comfortable AND fast. I suggest you give it I try.
