Fitting a new seat ( the one that came with the bike hurts me and causes numbness )

I am looking on ebay for a good seat new or in very good used condition. The seat that came with my bike hurts me. It is a San Marco that came with my 1986 Schwinn Prelude. Is there a formula for seat width? The middle of my seat bones is about 130 millimeters apart. I seem to be drawn to the the Selle Italia seats. They look great. What width should I be looking for? Any recommendations on a nice seat for around $ 40 or $50 new or used?

Have you tried adjusting the fore and aft of the saddle? It made a big difference for me when I purchased a new bike which had a firmer saddle than my previous bike.

Yes i have tried that. The seat is older and very hard suede leather. The curve at the top of the seat is in between my cheeks, making me feel as if I was rapped at the end of my long ride and for hours after. The seat is showing a lot of wear as well and no longer looks very nice. Worn Suede.

I guess I was just trying to find out if there was a formula or something that would be a good starting point? I think just about any new seat would be better than the one I have.

New saddle for 40 bucks is unrealistic. If your sit bones are 130mm apart, then a saddle width to match would be appropriate, but not the rule. Most LBS have a try it and buy it arrangement. Specialized has a guarantee on their saddles. Go talk to a dealer, bag the crapshoot on ebay.

Well I looked at a few of the local bike shops and they had nothing I liked. They did not have a very big selection. I read some reviews on line and narrowed down a nice gently used seat with 135 mm width that I like. I hope I did good. It looks like it will be comfortable. Got it for around $50 shipped. http://www.ebay.com/itm/221288363814...84.m1439.l2649

If it doesn't work out for you, go to a shop with a selection you like and try on for size. Back in the day, my shop encouraged customers to demo the saddle. Some still do. Take it for the weekend, but let us set it up for you.

Depending on the manufacturer the recommended width varies. For example Specialized recommends seat bone width + 20mm (10mm per side), so your 130mm sit bone width would call for a 150mm width seat. It depends on the saddle, but normally going wider isn't as bad as going to narrow. If you go wider your sit bones are still supporting the weight, but possibly your thighs may rub on the seat more (again this depends). However, if you're on too narrow of a saddle you almost always will end up supporting the weight more towards the middle and away from the sitbones. Having said that, I have 125mm width sit bones, so 145mm saddle would be recommended by Specialized. I have a Fizik Arione which is iirc 138mm width, but I find to be very comfortable, so I take sit-bone width recommendations with a grain of salt. Also, some people's bums just don't like particular saddles, and there are people who ride heavy Brooks saddles on their lightweight bikes just because they find them to be so comfortable. Personally, I think on your classic Schwinn that a Brooks would a beautiful compliment

There is only one way to find a saddle - SIT ON ONE. Try a shop with this tool http://bikefit.com/p-52-switchit-rap...-adjuster.aspx

After twenty+ years on many bikes and saddles (not seats), I can only agree with the above comment. I have tried dozens of seats, including a very early attempt to ride the Fizik Arione. I found it awful, because I was not ready for it. Now I have more riding behind me and my behind, it is the most comfortable seat I have. In fact, I now have five, and all my other seats are unbearable. Let's face it, when you first attempt to ride, it is uncomfortable to go any real distance. You have to train your body to accept the different pressures and effort involved. Also, the height of your seat is very important: too high by even an inch or even less, will cause chaffing and sores. Too low, and extra effort will be wasted. I am 68 years old (almost), and last year I rode 9000 kilometres. I intend to equal or do better this year. I feel qualified now, to pass on some of my experiences. As a final comment, I have the impression that many riders try the Arione briefly like I did, too early in their cycling career. Many of these saddles can be found on ebay very cheaply and tried, then sold again if you really don't like it. Recycling?, pun intended!

Every butties different...

My experience echos BFP's
Try some saddles. Group rides, buddies might be a way to check some out. I went thru a few saddles before I found one that worked. Then I bought 5 more of them and put them away before they could change the mold or model. I wound up with an Avocet O2air. I have two brand new, wore out two and have two mounted on different bikes. But, I rode a few from shops, a few from buddies that had one sitting around and I bought a few and then sold them pretty quickly. It was such a process it moved me to buy up some stock.

Attention web shoppers:

Actual Bike Shops Have Take Offs , new saddles that were removed from brand new bikes ,

when bike buyer wanted something else..

you can get them cheaper than the same saddle with the display tag attached ..

some shops will even take the 1st one back and swap it for another of equal value ,
and you can ride on the saddle on your bike, and experience how it feels.. .

I've been riding for 34 years and in that time have ridden a Brooks saddle for close to 30 years.My Madone 5.2 SL has a B17 "narrow" with around 10,000 miles and have had no problems.I went with a B17 reg. saddle for my 29'ER Cobia by Eddie Fisher and again no problems with more than 5000 miles on it.If weight is no concern to you you may want to give that a try.The reg. B17 is Brooks most popular and least returned saddle of their fine line.But some still have problems even with these.This is one of the most talked about subjects in cycling.Good luck in your search,go to Brooks website and get as much information as you can if you think you may want to try one of those fine saddles.There is a bike shop that offers a return after 6 months for a full refund on Brooks saddles.I'll try to find it and post it.
