    anyone ride with a shortened crank

    I asked this quetion to punkncat on another thread but thought I woud make it its own thread and may be seen by more eyes so here is my question. Does anyone ride with a shortened crank on the prosthetic side? I know a shorter crank will relieve pressure caused by socket pinch if thats a problem but any other advantages that you've found.
    I am an AKA with no quads on right leg and limited hams. I am able to apply pedal pressure although limited on the down stroke but no lift on up stroke. Left leg does most the work. A crank shortener can be purchased for about 100bucks and I plan on trying one but just wondering if anyone has actual experience or comments. Thanks

    Just thought I would add a website that does custom work in case anyone is interested. I have not used these folks, but have read that others have. http://bikesmithdesign.com/Short_Cra...anks_faqs.html

    I currently use 152mm cranks on both sides due to bad knee.
    Hope this helps.

    Van Ness rotationplasty here. I started out with a shortened crank due to a relatively limited range of motion. Since then I've discovered that I don't really need shorter cranks as long as the prosthesis gives me a little bit of wiggle room (though this needs to be done properly to ensure (a) the prosthesis stays on and (b) I don't get blisters/cuts/etc. -- and it may be more easier with a Van Ness than with a standard amputation).

    I've tried shortened cranks since then and find them frustrating because you really lose a lot of power... but if the choice is, as it was for me in the beginning, between less power and no power, they're by far the better option!
