Again, just having a conversation, yes, it does. But most modern clip on type pedal systems have minimal stack up. But, yes, you do alter the final adjustments to take into account setback, your belief system concerning KOPS (of which I am not a true believer) and of course your shoes, foot size, pedaling style and crank length. This is the magic part where we scientist have to fall back to, yeah, that looks right. It is a starting point to FINE TUNE from. If you have to make gross adjustments then you either have some really odd body dimensions or well, who knows. No accounting for the end extremities of a Bell Curve but most of us fall in the middle, very few to the extremes.

Well, it has been a good discussion, I have learned a few things, thank you. My saddles are higher, BTW, than the heel to pedal would give me without rocking or hyper extending. But, I am going to re-visit that method. I am trying to help a fellow get a new tri bike, about 3,000 dollars! He asked me to help fit him but I told him straight up, we better go get an expert on this, like the guy who fits at the shop he is buying from, lol, . I will hold his hand through. .
