After some achilles tendon pain coming off a big week of training, I decided to re-examine my fit. Using wrenchscience.com and Peter White's online guide to fitting, I gave myself a fit that involved lowering the seatpost about 2 cm and slamming the saddle all the way back.

Good lord, the bike is 10x more comfortable than it was. Lowering the seat post took care of the achilles tendon pain and my pedal stroke feels so much more fluid now, and slamming the saddle all the way back has taken the pain out of my neck and shoulders and changed the feel of the saddle from "rail like" to something like sitting on a stool.

The only issue is this.. my hamstrings! They are wicked sore after just a short ride 1.5 hours. I'm much more bent over now, but much more comfortable as well. And I'm not talking about pain, but definitely sore, as if I'm activating new muscles that haven't been used before.

Is this a good thing? Is this just the adjustment phase? Would it be better to slide the saddle forward a bit to share more load with the quads?
