I think I need a new bike saddle?

One of my bikes has a saddle that is over 20 years old, still fine. In my newest bike, I got to replace the saddle after 6 months.

Riding more miles doesn't fix anything, just will make it worse. Try adjusting it. Your mechanic should be able to do that while having your bike in the trainer.

There are some great answers already for you. Apart from your bike pants and bike saddle position, maybe its time to consider the seat material. Earlier seats were foam covered, and even now memory foam is being used on many but the best option is gel, Here is why:

Gel is a liquid and contained in a bag of a set volume, while foam compresses. What this means is that although they both mould to your body, gel distributes your weight across the pad, while foam compresses and becomes more solid at the pressure point which can create pin pointed discomfort.

Two options are here for you. Either replace your saddle or You may even look low cost option,bike seat cover that can offer anatomical design features that concentrate your weight away from your tender regions!

It’s strange that you’ve had the saddle for 6 years and are just now feeling discomfort. If your saddle has been fine up till now, I would advise you to think about another reason for your discomfort. Are you wearing new shorts? Maybe the chamois is poor. Did you recently change your for/aft position? Did you raise or lower the seat tube or the saddle? Or the bars?

Are you just riding a lot more? If so, give yourself some time to adjust before going with a new saddle.

Best of luck.

Unless the saddle is visibly broken or worn out, the problem is more likely in your position or setup.

Saddle should be as high as you can get it without rocking your hips as you ride. Too low, your knees explode, too high, you grind your taint raw. Net result is usually a slight bend in your leg at the bottom of your pedal stroke. Amount of leg bend is dependent on the flexibility of your hamstrings.

Unless you're already used to time trial aero position down on your aerobars, you may need to drop the saddle a bit and/or tilt the nose down a little more compared to riding up on the brake hoods since you're changing your body angle.

P.S. It takes at least a couple years of training and racing to build up to Iron distance. Unless, of course, you're content to slog in at midnight after risking injury and a high probability of DNF. Its not just a longer version of the same old triathlon, its an entirely different ballgame. There are issues that never come up at Olympic or even half Iron distance.

Try tilting the nose of the saddle down just a hair. That will put more weight on your sit bones. Get cycling shorts if you don't have them.
