If your hip joints are less flexible, you aren't able to stretch out your back to reach the longer stem position, so you compensate by bending (rounding) your back. That in turn could put more strain on your lower back and hamstrings.
Can you touch your toes while standing with straight knees?
Not easily - I haven't been good about stretching recently so it's a good possibility it's just a flexibility issue. Have never been real flexible to begin with but it's gotten worse.
jpescatore - interesting about mving the cleats because I recently did that on my own, mostly due to a hotspot on my left foot.
I'll work on flexibility and see what happens, then possibly go for a fitting. The closest shop that is known for fittings is a couple hours from me though.
