I'm 5'8" and 155 lbs with "childbearing hips" and just love my Brooks B67.
No pain anywhere, and the springs are marvellous for those of us with wide pelvic girdles that really need to *shift* on each pedal stroke.

The Brooks B68 is the same idea, without the springs.
And you get 6 months to try them out, with no questions asked!
