Maybe. Depends on other things we may or may not find out.

I have no experience with hammock type saddles. So that might change how any clues you give are interpreted. But going forward with your upper body when you pedal harder is a natural thing. And to some extent ones position on the saddle might change too. I and some others will tilt our hips/pelvis with our upper body to keep a flat back. And that sometimes on some saddle shapes involves the position on the saddle changing as that tilt of the pelvis causes us to roll on our ischium. Some prefer to keep a upright hip/pelvis and bend at the back. Which works for some. Maybe more than a few, but not for me. You'll need to figure out what works for you. I see in the pro athletes a little of both. So evidently it's a personal preference. And reasons that seem valid can be made for both.

As to why you feel more weight on your hands when you do this has me a little puzzled. As normally there isn't much much actual change in the position where you sit to make that big and noticeable difference. So are you moving your butt forward a significant amount when you pedal harder?


Other things might be you got the wrong size bike. Or the wrong bike model for the position you want to be in. I notice your bars are angled up very high. Is that for the bar height you prefer or to bring them closer to you?

Your saddle also looks like it's already forward in the clamp, but the picture angle and the dropper post might be deceiving.

Probably the first thing you should do is make sure the saddle is at a proper height for you. To high or too low will make other things act on you differently.
