    Hi this doing my head in trying to work this out!

    If I have a32 tooth cranks and a 34 tooth cassette running 650b what front ratio would I need to achieve the same with 29er wheels.

    Also would I be right in saying you would need to put more force in when spinning up 29ers due to the increased lever?

    Either 32 front/36 rear or 30 front/34 rear would get close I think.

    Have a look on here… http://sheldonbrown.com/gears
    I think it’ll help – though I suspect dpfr is probably right!
