    next thing to try on my recumbent is a cycling idea that ocurred to me after chatting to my specialist and being told that my left hip was shot, making my left leg some mm shorter than the right, ( due to the hip rotating outwards mainly).

    My bike is now a pretty good fit but i can easily see my knee pushing away from the frame, so ive bought a 170mm left crank to put on my 175mm crankset that I have just fitted. Im hoping it will make riding less painfull again & will post results asap.

    I don't ride a recumbent, but have similar problems. I changed my right crank from 170mm to 160mm and it's much better. The angle between thigh and abdomen doesn't have to close as much, which relieves the pain and I'm not pointing my toes at the bottom of the stroke. I'd like to try a 150mm, if I can find one.

    Is it not worth trying to work on your hip flexors before getting mechanical with a solution? http://www.lifetimeendurance.com/public/228.cfm I have had a serious leg length issue that chiro and exercises has helped with immensely. Mine is down to 2 prolapsed discs.

    As OP, legs are different lengths due to historical trauma. Since taking cycling as a proper hobby, I have always used a 170mm spider on the right and a 140mm arm on the left. My saddle is also off set to the left of centre, because that's the placement that I don't suffer leg rub on either side. A screwey pelvis because of screwey legs I guess.

    There's no shortage (ha!) of 150mm cranks on eBay, as long as you stick to a square taper bottom bracket.
