Any idea of the maker of this fork, and if any good for using it?

Could be a trek. Here’s what I pulled from a 2100

The fork on my Trek OCLV 5500 frameset looks very similar to that......

SR Litage?

Pop on over to eBay. There’s a few listed now.
I’d post a link but my computer has decided that cut and paste is no longer a feature that it chooses to supports

Litage:

So I would agree it is a Trek.

Yah,..... that SR Litage fork look more similar to a Vitus 979 fork.

So this is the front fork ?, not the rear ?

The "rear fork" is another term for the chainstays.

So, not the rear.

You realize this was humor ?, The thread title mentioned the “front” fork, there’s no such thing as a “rear’ fork as you so helpfully point out.

I think you missed the sarcasm re - the thread title.

I don't think you guys are reading very carefully:

Wow. You know how to take everything too far to act like you're winning. It's rather funny and sad to read your posts, sometimes.

How did you misread my post, misread Steve's 2nd post, and come to the conclusion that I did something wrong by pointing out that the OP didn't get anything wrong by using the term "front fork"? I realized Steve was making a joke, but I thought it would be okay to point out that the joke doesn't work because "rear fork" is a real thing.

And then you insult me for having to point this out, twice? What's wrong with you? Get some manners.

I didn't misread anything. I immediately correctly read Steve's post as sarcasm, which he stated it was in a post that he made a matter of seconds before mine went through (I did not see his post yet when I began my reply) and then instead of acknowledging the sarcasm you kept laying it on by quoting St. Sheldon. Based on the general flavor of so many of your posts here, where you interject in such a way that you clearly just want to prove people wrong for the sake of doing so, there really shouldn't be any limit to how often you get a taste of your own medicine. Good day.

In 36 years of cycling I have never heard of the rear triangle on a bike being referred to as the “ rear fork”.

Could be a Kinesis.

Sure you did. My post was in reference to the fact that Steve's joke (which I realized was a joke), didn't quite work because "front fork" and "rear fork" are actual bike terms - as Steve confirms he was not aware of.

But you seem confused that I didn't know that Steve made a joke. But I did, so that was your first mistake. Your second mistake was to act like I was insulting you for pointing out that you were missing my point. Which is strange that you got offended, since you had just posted to make sure I was aware that you thought I missed the point.

Whatever "good" you think you're doing by calling me out, you're just highlighting that you are the confused one and that you have some sort of emotional investment in showing me up. While all I was doing was letting Steve know about a cycling term he probably wasn't aware of. And I did so politely.

So you can go bother someone else, now.

Thank you for pointing me to that Trek fork.
Sorry for my mistake, and let it go.

Could be. These are the ones I remember being common, but Kinesis made a lot of forks over the years.

You didn't make a mistake. That is a front fork.

For the front ?

That Kinesis fork has flat inner faces under the crown the subject fork has a more rounded inner face.
it's definitely a Trek fork.
