I want to take a few cm off of my steerer tube.
Do I just hammer the star nut down a little further and carefully cut the tube with my hacksaw, or is there more to it than that?

It's an alloy steerer?

Yep. According to Trek it is.

You can push it down further and cut it if you want. I would try and remove it of possible. You wouldn't want to push it down too far, or not far enough, then damage it. Can you push it all the way down, and remove it out the bottom? If so, I would probably take it out, then cut the tube, and reinstall.

I went to the website on my year and model of bike. It's alloy. Is there a cheaper material to make steerer tubes out of? If not, then that's what it is.
It looks like aluminum. Like the rest of the bike. Definitly not carbon or titanium. That's for sure.

I just need to knock it down about a quarter of an inch or less. Maybe an eighth.

OK. Have fun. Just make sure it is a "Straight cut", not at an angle. Use a good file afterward to smooth out the edges, and level it off square.

I have had my trek steer tube cut a few times, and it has the same type of steer tube as yours. They said if it is a small cut then you should not have to remove it, but if it is more than about 1 cm then it is worth to take it out. Remember cutting the steer tube is not reversable... so besure that is where you want it before you cut...
BTW, I cut my steer tube 3 times before I was happy... it started with 4 cm and now it is about 1 cm tall... and it is not going any lower...

I too have a Trek 2100. My steerer tube came with several "spacers" under my stem. I did not have the courage to cut it myself, and I thought I would see how I liked it so I took a spacer out from underneath the stem and put it on top of the stem then put the cover back on. I just may leave it this way unless anyone sees a problem with is.

Do as LFT153 recommends to figure out exactly how much to eventually cut. Make sure you adjust the headset properly after you switch the spacers. To cut the steerer use a pipe cutter then deburr.

If you happen to have one large spacer only then you'll need to visit the LBS to get a few smaller ones (to match the height on the large spacer) so you can play with the height.
