    Well one is longer than the other. The 175s will get a little closer to the ground and a little higher on the top end.

    I am 5-11 I went from 170 to 175 quite a while ago...

    The first two weeks my knees hurt till they stretched out enough.

    Then it felt like I could finally take a full step on the pedal stroke.

    I had pedal strikes before I switched and I still get pedal strikes....it is all about technique anyways.

    I would not go back willingly to 10s.
