Excess pressure on L sit bone.(5 posts)

Excess pressure on L sit bone.titansprodigal
May 6, 2003 6:35 PM
I'm putting alot more sitting pressure on my L sit bone than my R resulting in alot of discomfort. Ive changed saddles which helped some but still the pain is there.
After the two hr mark the pain eases up some. But getting to that point is difficult i move constantly on the saddle trying to find some relief. Needless to say i get sores on that area very easily, none ever on the R side.
Any suggestions?

If it were me, I'd try lowering the saddle a tiny bit, maybe 1/8", and try some different shorts. I find a vast difference in shorts padding, and difference between new ones and old ones (worn out).

Any chance you have a leg length difference?

hey doug, yeah i got a LL discrepency, tilted/twisted pelvis but im still able to race expert mtb and train on the road 12hrs p/wk w/ occasional pain flare ups in the sacrum, ive learned to deal w/ the pain. About a 5 degree bend in my R knee at six oclock and < than 3 deg bend in my L knee at six oclock. Ive tried a shim but it doesnt do much, thinking about a shorter crank on the L side.

thanks

Hey Titan

I have similar physical things to you and race Cat2 however I have looked into and corrected my LL and twisted pelvis.

Very few people are 100% symmetrical.

The bike has to be made to fit you plus you need to do some structural self help, stretching, chiro, yoga etc to loosen your back and hips up. Every ride when it flares up is damaging your body and robbing you of power.

I have a 6mm LL discrepency and have a 4mm packer under the left foot, this helped a lot in easing the hip pain I was getting when I crossed from the mtb to the road a few years back. Different crank lengths would also compensate for the LL.

Also you can set your saddle off centre until your sit bones are resting equal on the saddle to allow for your angle of pelvis twist. If your stem is too long you may be over-reaching which is putting more pressure on your lower back, maybe raise your bars a bit and/or shorten the stem.

Basically bikes are not made to fit the morph of people, with what is a common LL and twist morph. Many just plug on in pain and then get injured.

A really talented girl at our club has hammered her body into a sorry state just by toughing it out, dealing w/the pain however her racing was starting to really suffer. I offered her some help and she is fixing up now. She had a LL and a pronating R foot giving her knee and quad problems.

It is possible to be relatively pain free on the bike you just have to sit where your body needs to be to peddle circles. Pain is a warning.

Hope this helps, happy to go into it further if you want on or off line.
