My pelvis is very upright rather than tilted forward like most women. As a runner, I'm built for distance and not speed--I run with butt in and hips forward for max efficiency.

I just got a Trek WSD 1000. One of the qualities it boasted was a steeper seat angle to get you more over the cranks. But I can't get any kind of speed or efficiency unless I perch myself on the very, very front of the seat to get my legs under me--the pedals still seem too far forward from the seat, putting the most stress on my hamstrings and knees rather than powerhouse quads.

If I lower the seat and actually sit on it, it forces my legs too far apart and too far ahead of me.

So, am I just a freak of nature or am I doing something wrong? Any and all advice appreciated!
