When I use KOPS to position myself on my bicycle, I get a lot of hand, trapezius, shoulder, and upper back pain. It seems my weight is too far forward. I have to have my seat almost all the way forward to achieve KOPS on my 56cm frame.

My question is, would achieving KOPS on a 54cm frame change anything as far as how forward my weight is? I know it would change my weight distribution on the back wheel.

I know changing from a 100mm stem with a 17 degree angle to a 110mm stem with a 7 degree angle helped with pain, too.

What do you guys think? Thanks in advance.
