Hi,
I have a loaner Giant Trinity Composite 2 (2012) from a friend and it desperately needs to be adjusted to fit me better. The problem is that neither my friend nor I can figure out how to adjust the saddle. Before making arrangements to take the thing into a shop and look like a complete fool, I figured I would check here. I am encountering into two distinct problems:
1. Saddle height. When I loosen the clamp that holds the seat post in place I am able to raise the seat post but with one problem, the clamp sticks to the post disallowing any height change. The clamp may simply be "stuck" to the post due to lack of movement over the past year, but before I get out some tools and pry the clamp off the post I figured I would check here.
2. I need to adjust the saddle angle, but I can find no alan wrench holes underneath the saddle, near the saddle, around etc. I inspected this thing for a very long time and searched the internet for any sort of manual or 'how to' articles or videos, but I have nothing. Absolutely nothing. Is there some sort of trick that I don't know?
Any help with either of these problems would be greatly appreciated as it would save me significant time and embarrassment.

Thanks,
Thoroughly puzzled

Photos? Or are we to do the internet search thing for you? Andy.

Giant may only be the buyer of thousands of them, so who actually made them , printed the name on it.

now get back to Work !

If it is the Trinity Vector SLR post we are talking about, then...

The clamp is not an ordinary clamp, it just holds the post lightly. The bottom of the post must rest on its stop in the frame.
Quote from this video: "Make sure the post bottoms out in the frame".

To lower the saddle, cut the post.
To raise the saddle, use the special Vector SLR spacers - page 27 in the User's Manual.
Also on page 27, you can see the hex head bolt on top of the post for angle adjustment.

Thanks for the responses. Hopefully these pictures will provide some clarity. I don't think it's a case of the post needing to be cut (or spacers added in my case) since the post appears to rest on the post clamp to an extent and not the post itself- it looks similar to the Vector SLR, but not quite the same. Also. this appears to be a genuine Giant as best I can tell.
The pictures should show: 1, how the clamp appears "stuck" to the post. and 2, how there does not appear to be any screws or bolts under the saddle to change the angle of the saddle. Any help would be appreciated.

I'm not familiar with that seat post clamp, so I'm only guessing here.
I think the clamp is only lightly stuck to the post. Possibly some sort of assembly (anti-slip) paste has been used, which has gummed up and "glued" the clamp to the post.
Or the clamp bolts might have been torqued too much, so the clamp has slightly deformed the surface of the post and then wedged itself into the deformation.
Again, I'm only guessing but I think if you tap or pull the clamp straight back, it will come loose.

In the first of your pictures, the saddle adjustment bolt is visible on top of the saddle clamp. If I remember correctly, you'll need a 13 mm open end wrench. It's very fiddly to get at, you'll probably have to bend or flex the wings of the saddle to reach it.

Thank you very much, you were right on both guesses. The clamp popped right off of the seat post and I just had to bend the wings of the seat to access the bolt. It is a much more comfortable ride and I greatly appreciate your help.
