Recently got a bike fit and the fitter told me my seat was too soft and that a firmer seat would be better when go on longer rides.

What would you recommend?

Bike is a Trek Madone 4.6 with the stock Bontrager Affinity 2 Saddle.

Nobody else has your ass. You need to try some yourself. See if you the shops in your area have some loners or take offs.

True... and makes sense.

You will get real help in The Fifty Plus Forum.

You're probably right. I just figured the answers would be more entertaining here.

Maybe i'll "borrow" one of the seats from my son's 3 bikes.

I'll just make sure the take measurements prior so I can put them back the way they were.

I suggest looking at the Prologo line. They have saddles of all shapes - flat, semi round and round - and of really nice quality. I use the Scratch pro.

I found a couple of online places that would demo seats for about 10-14 days. I ended up with a Selle SMP Dynamic.

Off the bat, it didn't look like something that would fit well....low and behold, comfiest one of the ones I tried.

Just another thought:

Competitive Cyclist now has free shipping on orders over $50, and a lifetime return policy. Sounded like a nice saddle demo opportunity, so I have one en route.

I tried a Cobb Cycling (V-Flow) Plus last summer based on a friend's recommendation. I really, really like that saddle When I got a Madone earlier this year, I ordered a second Plus because I didn't like the stock Affinity saddle. To my rear end, the Plus has great support in the right areas and I don't get numbness "down there". If it matters, I'm 45 years old, so I'm getting "older and slower" each day, too...

Check out the Cobb saddle and also read their warranty. They'll swap saddles for you if you get a saddle and it doesn't work for you. You can even call them directly to discuss which saddle they'd recommend for you. I talked with them before I ordered my first Plus.

FWIW I'm doing well with the Specialized line, notably the Toupe. They come in different widths and different amounts of padding (e.g. the Gel is a little cushier than the standard).

Find a Specialized dealer, they'll help you figure out what width will work for you.

Are you having issues with the saddle on now or looking because the fitter said this to you?
If you are not having issues test the one you have now out before starting to search for something you may not need.
By long rides what are we talking about everyones idea of long is not the same.

Your best bet is to find a bikeshop with a demo program.

What I do is buy seats secondhand to try them out, sell them for roughly the same amount if they dont. It is a relatively inexpensive way to try a new seat every now and then, though a bit of a hassle if you want one now.

For me, I found that I am easier than others because I like whole range of seats. Mostly though, there is one characteristic it has to have, and that is that it needs to be wide enough for my sitbones. I also hated the bontrager infinity saddles. I own a fizik antares on one bike and the aliante on another and like them both. I also have cheap selle italia seats on some older bikes and they are also fine for anything under 3 hours. I guess I am easy.

This would be a good start, providing that the Specialized dealer you choose has their butt-o-meter. It's basically a plank with a pad on it, with a ruler along the pad. You sit on the pad, your sitbones leave indentations on the pad, and they measure the distance between the indentations. That gives you an idea what width saddle you need, and you choose from among saddles that width. If you don't find a Specialized saddle that suits you, at least you have the measurement you need to pick other brands. For me, I need a saddle of at least 150mm in width; this eliminates most saddles.

Brooks Professional. Anything else is a waste of time according to my very experienced 59 yo 40 year history of cycling ass. If you don't agree with me you are wrong. Period. End of discussion. Fini.

What?
Not all of us have a tender ass

On my standard 25 and 40 mile ride, i'm OK. But on 50+ rides I am a bit sore.

In my opinion if you are good for 40 miles it’s not the saddle but more of conditioning yourself for more miles in the saddle at one time that only comes from putting in the mileage and learning to move around some and stand at regular intervals to relieve the area. This all needs to be done before you start getting sore so start standing well before you start to fill anything it doesn’t have to be long just 30 sec. at a time can make the world of difference.
If the saddle is really wrong it happens way before 40 miles.
