Narrow saddles to prevent sciatic irritation?(6 posts)

Narrow saddles to prevent sciatic irritation?PT
May 14, 2002 5:56 AM
My relatively recent return to road cycling has lead to an increase in sciatic pain. I feel as if my saddle is too wide, pinching into the back of my leg as I pedal, and consequently irritating my sciatic nerve. I have used two saddles, a Terry Ti Fly and a Bontrager C20, and view each with a total lack of enthusiasm. I've got pretty narrow hips and wonder if a narrower sadle (not just at the nose, but towards the stern as well) might not alleviate some of the pressure on my sciatic? Any thoughts to if this is a reasonable hypothesis? Any suggestions for a narrow saddle?

Trade or buy?tad

I have a Terry Dragonfly saddle that I will trade you for the Terry Ti Fly! It is much narrower than the Fly so it might work for you. Check their website for exact specs.

Or I would be willing to buy the Fly if you just want to sell it. Let me know!

Sciatic irritation can be triggered by a lot of different things. I don't thing just because you have narrow hips it follows that you need a narrow saddle. A lot of casual cyclists have those big honkin' wide body seats with springs, and I haven't heard of a epidemic of sciatic pain related to that.

But is it possible that the width of the seat is causing the pain? Yessssss....but it could be something else also. Cycling actually helps my sciatic pain. Go figure.
check leg length, small differences can cause this problemmaximum15

Sciatic nerve irritation can result from several different fit related issues. For example, excessive pronation of the feet can cause overuse of the gluteal muscles, including piriformis, and thus sciatic nerve irritation.

Ideally, you want your ischial tuberosities (sit bones) to be supported by the saddle. If you have narrow pelvic structure a narrow saddle might be better. Also, you may want to examine your saddle height. Having the saddle too high can excaberate any leg length discrepancy and result in problems. Try lowering the saddle by 0.5-1.0 cm and riding easy for a couple of days to see if it feels better.

You may also want to be sure that your seat isn't too high. That forces you to rock your hips to reach the pedals.
