Not an expert either and I feel like your elbow pads can move forward slightly to open up your upper body? Changing the frame or bike is a big deal and too much hassle, so I wouldn’t go that far since you used to feel comfortable before.
Thanks - I’m actually rotated forward as far as anatomically possible without going into an anterior pelvic tilt. If I tilt the saddle down more (currently it’s a slight drop) I start to fall forward and my quads get more overloaded. As far as moving my elbows further forward, it doesn’t feel comfortable when I do that, and I can’t get as low with my shoulders and head. But there is plenty more reach available in the Shiv. The pads are only in one of the middle positions.
Since my back strain I generally have not felt comfortable on the bike. But before that, pretty comfortable.
why are you trying to avoid an anterior pelvic tilt? that’s literally the entire goal.
Your thoughts are outdated.
Long isn’t comfortable because you aren’t used to it
Low is not better. Narrow is. Go look at Sam long on the bike. He barely has drop from his saddle to pads
On a Tri bike the pelvis NEEDs to rotate forward. That’s kind of the vibe. You need to adjust your mindset as well as your position.

Exactly. He needs to understand HOW to sit on Tri bike
I’m not super special but look at my pelvis.

Shit. I meant to link my OF
I think others have said this, but looks like a tri specific saddle, which means you want to rotate your hips forward they are built that way(ISM saddle)? Rotating forward/anterior tilt is the point of the saddle and TT position. As far as anything else, I can’t comment on. You want anterior tilt.
You don’t know how to sit on that saddle properly.
Are you confusing pelvic rotation and tilt? Because I just can’t believe that an anterior pelvic tilt is good for cycling or good for anything really. It disengages the core, disengages glutes and hamstrings. What am I missing here?
Again, I think we are talking around two different things. Anterior rotation (rotating forward) is definitely a good thing. And I am rotated as far forward as anatomy will allow. Pelvic tilt is a totally different thing. Everything that I read (and my own experiences) discourages anterior pelvic tilt. It shuts off the core, glutes, and hamstrings.

Asks for advice
Is given good advice by multiple people
Ignores it all because he knows better.
Best of luck dude
That could be, I must not be understanding. Professional bike fit might be best solution to your questions.

Pelvis compared to torso you’re in posterior pelvic tilt/rotation. Same damn thing. You’re not even neutral.
When I do an anterior tilt on the bike, my back hurts (more), my asymmetries become more pronounced, and my quads light up. I do appreciate your advice, and while you very well may be generally correct in your assessment, there’s something else/more going on that I don’t have a handle on. Definitely due for a professional bike fitting - it’s been two years and there’s been a lot of water under the bridge since then.
If you can stand up straight without pain you can sit on the bike better.
You probably don’t have room to rotate forward with your hips because that will snake you need more reach in your cockpit
Go longer, raise the bars for a bit, and rotate your hips
Or I can recommend a great fitter in Greenville SC who will charge you to tell you this same stuff 😉
Thanks - I’ll check back in after a few weeks with an update. Apologies for being stubborn to good advice - it’s a feature, not a bug 😉

What is the difference between pelvic rotation and pelvic tilt?
Long story short, you have way, way too little reach on your bike and you’re probably too low as well. But those things aren’t mutually exclusive.
When you try to rotate your hips forward, are you disengaging your core and hyper extending your back? When I’ve done this, it puts a lot of strain on my back. So try to rotate your hips slightly less and keep your core engaged. (Suck your belly button in). When you do this, you should feel your glutes, hamstrings, and quads all working together as a system.
