>>1371873I've tried noseless (spiderflex, spongy wonder), ISM, sq labs - none of them worked for me. However ISM is relatively very popular and there is a triple crown bikepacker who did it all on a spiderflex. So it can work, but it likely won't work for most people.
The problem with noseless is... There's no nose. You need the nose to have maximum control of your bike. Without it, you are going to be muscling the bike to keep it where you want it. Again, not impossible but still not optimal. The other issue is weight distribution. The nose of the saddle takes pressure from your hands and puts it on your perineum. It's enough to make a big difference on your hands and wrists. Without that support, you will have a lot of weight on your hands, unless you set you bike up in a very upright riding position (something I want to explore)
I've got one last saddle I have not tried that I feel optimistic about called the Rido R2. It keeps the weight off of the area but still has a nose that is dropped about 2cm below the sit bone area. Set up correctly it would theoretically solve the handling issues but not the wrist pressure issues
As far as upright riding, I think a noseless saddle could be redundant in this situation. With the bars significantly above the saddle you sit more in your sitbones. The problem is massive loss of aerodynamics.
Consider all of that and try a month away from cycling, try running instead. If you feel an improvement down there, it might be worth reconsidering your saddle, your bike fit, or bike itself. I don't have a absolute answer for you since it really depends on the guy. Unfortunately there's a lot of angry talk and denial around the topic, and it is complex enough that the average rider will not be able to navigate the information, so it is rightly not emphasized by the industry. It's enough of a problem for me that I've drastically reduced my riding until I figure out a fix that works for me, and I've started running
