I’m on a brand new bike and am confident I’m on the right size bike, however I’m sure my position needs to be tweaked. When I ride on the trainer I’m getting numbness in the nether region. What should I check out as far as fit to relieve this?
BTW, this is happening on the trainer even on short rides (20-30 minutes). I have not been outside on the road and likely will not for several months.
This is NOT a good thing. It might be fit related, but it is more probably due to your saddle. Are you riding a TT or road bike?
I’m on a Shiv with an Adamo Road saddle.
I switched to a Cobb JOF (similar to Adamo) and while I still get some mild numbness after 45 minutes if I’m riding zone 2 or less. I’m ready to stand up for a bit anyway after 45 minutes. At tempo effort or higher, no issues. My Cobb V-flow+ was also better, but still didn’t fix it completely and I was getting a boil in one spot too.
Actually, I can’t ever recall doing a 2 hour ride without even minor saddle sores, but that’s where I’m at now with my JOF.
Now my Bontrager OEM saddle? Crap, I’d start having numbness after just 10-15 minutes sometimes.

My first thought is that you’re cramming the whole Adamo saddle between your legs. Try sitting on the very very tip of the saddle, with your man parts hanging well off the front. 80% of the saddle should not be sat on. You should only be sitting on the first few inches of the prongs. See if that helps…
From my experience, trainer rides seem to put greater pressure on the nether region (especially at lower power efforts) and will exacerbate any fit/saddle issues. Where you are sit on the saddle, the tilt, and height will all play a factor. A good example: I just switched to a different frame and had a some discomfort. It turned out out my saddle was slightly tilted up from where I previously had it set. A few millimeters made a huge difference.
Seat angle is jamming nose into your crotch nerves. Oddly, pointing the seat UP is often the fix. This is because you will sit farther back on a wider part.
I had this issue. Never a prob outside, but “locked” in place on a trainer, would go numb after about 30min. Changing trainers helped me. Currently use a Kinetic Rock&Roll. The side2side movement allows the blood to keep flowing to the boys.
If your balls touch the seat you are too far back. They should hang over the front tips.

+1. The back of the saddle is for sliding back when sitting up on steep climbs. In aero, your sit bones are near the tips.
Keep in mind that you might need ot slide you saddle back to keep the same effective position relative to the cranks and the same reach.

Just keep moving it all over the place while on the trainer. You’ll nail it. You’ll lose the better part of a ride figuring it out, but it’ll be worth it in the long run.
Can be a number of things, including:
It’s always worse on the indoor trainer, because the pressure is constant. On the road it’s better. Even when you’re not standing, you’ll bump up and down a bit, and unconsciously shift your weight to your hands and back.
I’d say numb nuts is worse than numb stick. You do need to fix this. You also need to check if it’s very temporary (feeling comes back in a minute) or long lasting.

Thanks for the feedback. I’ll thinker with a few things and see what changes. Regarding nuts vs. stick…it’s the entire area. Also, it is very temporary…when I hop off the bike to run on the treadmill the feeling is back by the time I’m running. Also, on Saturday I did 2 hours on the trainer and toward the end I would routinely stand and get some relief.
Many of the suggestions seem to be very good as I don’t think I’m even “sitting” correctly. I’ve been focusing on putting my sit bones on the wings of the saddle, which sounds very much like the wrong thing to do.
Sit bones on tips! All junk hanging. Less padding is better when on aeros. Prob need slide that saddle back 3 inches
It should almost feel obscene. As if the prongs are almost going in the no-no hole. It is at that point your sit bones are on the tips of the prongs. If by “wings” of the saddle you mean the rearward wide areas of the saddle your are waaaay too far back.
Ask your wife to move them around in her purse a bit?

You don’t read so well, do you?
