yet another thread from me... adjusting saddle angle

So, I can't seem to adjust the angle of my saddle. I want to tilt it a little back. It's not incredibly bad, but i feel like a bit of a tilt would be slightly more comfy. anyway, i just can't seem to figure this one out. it's the default that came with my trek 520, and looks like the red one at this page. Anyway, it looks like there's two curved parts with teeth and i should be able to separate them and adjust the angle. however, I simply cannot get the two parts apart. is something wrong there and maybe it's stuck so i should try banging it with a hammer or something, or is something else going on here?

edit: trek says it's a bontrager select seatpost

On my 1984 Trek (bought used last year) those curved parts had kind of locked together, not from rust, but from a really snug fit and the bolt being very tight, so even when I loosened the bolt they didn't move until I tapped them apart. Of course yours is not 21 years old so I don't know if that is the problem.

it seems like that's the problem. maybe i just need to tap it more vigorously. but damn, i was hitting it pretty hard.

I would make sure the bolt is really loose, then just grab the front and back of the saddle and lift as you apply a tilting force.

I wouldn't pound the seat with it bolted together because you can damage the rails and you really don't want a failure. If you have a digital camera, take some photos of it from several angles so you can see how it goes back together. Put some tape to show depth in seat tube, and put some tape around the saddle rails so you can see where to clamp them again. Then take it out of the bike, unscrew the main bolt all the way out, take the seat off, and chances are pretty good that you can get all the parts apart without much difficulty. Liquid Wrench, maybe. Look at it and fiddle around until you see how it works. Put a thin layer of grease in as well as grease the bolt. Put it all back together. If necessary, go to your local bike store. Maybe the seat/post is pretty worn. You don't want a catastrophic seat or seat post failure that results in bicycle parts being embedded in your rear.
