Leg length differences
How easy is it to detect a difference in leg length? Can you just measure? I had a chiropractor tell me I had one, but didn't get the details.
How big does the difference have to be to affect your pedaling mechanics and power?
TIA,
Roger

I posted this in a previous thread. Do a search for leg length discrepancy. As for power and mechanics, I will leave that to those that have more experience with fitting. I am learning myself and do not what to steer you wrong. Hope it helps.
"The most accurate way to measure leg length discrepancy is serial x-rays but this is done only in significant cases. It is easy to determine if you have a leg length discrepancy at home.
Take a tape measure and measure from the belly button to the bottom of the inside bump on the ankle. Do both sides. That measures the soft tissue distance between the two legs. Soft tissue differences may be tightness or possibly a scoliosis. (Chiropractor?).
Then measure from the points on each side of your body where the point of the pelvis sticks out front (ASIS) down the same side to the same point on each ankle. This actually measures the bony length.
If this is off, lay on your back and put your heels to your butt (bending your knees). Have someone look at you from the front. If one knee is higher then that means the tibia is longer.
Then look from the side. The knee that is front means that femur is longer. If you have a bony leg length discrepancy see a podiatrist.
