Been having some really nice weather for this time of year. So this is how I look like now. My saddle was raised a few times, then lowered once, so it's a few mm up compared to the pictures from the beginning of this topic. I moved it way back though. It's moved back as far as this saddle can go, and as you can see, I'm still sitting pretty far back. That is to accommodate riding with a tilted pelvis as you taught me.

Also, the saddle is tilted upwards very slightly, which relieves pressure on the perineum.

I rode recently about 100 miles pretty much in this posture. I had no shoulder issues as I had with the pictures from the first page. I did have a lower back ache, but it's not the same type of pain as I had before. When riding like in the pictures from the first post, my back felt cramped, while riding like this for a few hours makes my back hurt seemingly from being stretched out for a long period. It is way more bearable like that, but still not ideal. I take it it's a flexibility issue then.

Looking at this gif it seems like my saddle is still too low, but raising it stretches me even more it seems, and also, it might be an issue with the camera lens, that is, the saddle may appear lower than it really is on this gif.

So what are your thoughts now? :)

Ah ha! So I was right; saddle back, more drop!

Overall looks good, torso balance with nice bend in elbows, nice plevic angulation.
IF:
1. you don;t have a lot of long climbs that you ride (position looks like a nice 'long climb' position...)
2. Your pelvic angulation doesn't get more upright.
3. Your torso doesn't feel more pitched forward

You could even go up on saddle extension. A few more mm. would smooth out the pedal stroke as cadence increases, on flatter terrain.
Going up 3-5mm usually means also moving forward 1-2mm.
The back pain is mostly about getting accustomed to the new tilt. It should subside after some miles...
If everything else feels good, and power feels good - doing 100 miles like this is a pretty solid stamp of approval. :thumb:

If you are not doing core exercises, start. It should help considerably with the lower back pain. An increase in cadence by going to lower gear at same speed can also help with lower back pain.
