I’ve been tweaking fit and have had several professional bike fittings last couple years. I was still getting sore neck and upper back due to some spinal issues (nothing serious).

Recently I went to a shorter stem and less drop. That helped. I then focused on slight tilting my pelvis forward. That really helped neck etc but I over did it and suffered low/mid back issues (after zero problems ever). Today I changed the saddle tilt slightly (more level vs nose down) and had a more neutral pelvis with a lot less tilt. Bingo! Not only did my whole body feel better, but I had more power. I also felt like I had better control on descents and more neck mobility to look around comfortably.

Good for you. Glad to see that you are trying stuff out to see what it does for you. It's especially good that you seem to be aware of what your body position is. For many it only seems that they have a pain or they don't. What their body is doing at that time they don't seem to know or care.

Also realize that sometimes after a change, things might feel funny or odd, but if you give it several rides to get use to it. Some pay a fitter big dollars to get a fit, but when it feels funny to them after the first ride they change everything back to what they were use to. Go figure!

I am a huge proponent of "riding with the wrenches". The tools for seatpin, clamp, stem , bars (and brake levers for those early rides on a bike before the handlebar tape goes on). Tweak, ride, observe (both during the ride and how I feel afterwards).

I've got two bikes with identical fit (despite different seats and slightly different handlebars) that are that "ahhh!" Doesn't matter if it's flat, up or down, wind in back or in front. (Well my legs aren't fully on board with that.)
