Indy Fab fork vs carbon?

Been riding a steel Planet X the last few years and I really love the bike, but it's got a lot of very worn parts and while I'm playing the rebuilding game I've started thinking about a new fork. The bike gets used almost exclusively for cx racing, with some extracurricular trail riding and allycats thrown in. The setup I've got (w/ TRP RevoX alloys, hanger is right under the stem (but I could probably DIY a hole and mount a fork hanger)) has been fairly tetchy in terms of judder and noise, but usually manageable. The question is - with all the fancy dancy carbon forks available out there, will replacing the existing steel fork be a significant step up in anything beside weight?

Probably not. How the fork rides depends more on design than material. If there's something you don't like about your current fork (too stiff, too flexy, wrong rake, etc.) then you can probably find a carbon fork that will correct it. If you're happy with the IF (which is definitely a quality steel fork), carbon will just shed some weight. I opted for a steel fork when I had my custom CX frame built because I didn't want to have to worry about hidden crash damage when racing (and a few hundred extra grams can't make me much slower than I already am ).

I have a carbon fork road bike, a steel-forked gravel bike, and used to have a carbon fork CX bike - other than weight and the bike's geometry, I can't tell the difference between the three.

That being said - steel forks are HEAVY! So if you want to drop some weight, it is a good place to start. The steel fork on my gravel bike must weigh 3 lbs - but it is non-rotating mass, and I could stand to lose a few pounds myself, so it is a non-issue.

Been thinking of this myself. Mainly for weight. The IF fork is nice though. Doesn't have fender mounts so that's another thing that I'd want in a new fork, but for me, my IF fork is 1" so I may have more issues finding a new fork. Is yours 1-1/8"?

I came from an aluminum fork and recently bought a cyclocross bike with a carbon fork. They weigh about the same. The carbon is stiff like aluminum. But imo it soaks up the edge off the bumps like it's a shock fork with 1/2 inch travel. The fork I have is designed to take the edge off which is Awesome. If you want a carbon fork that does well with bumps and fit fender mounts look at BMC carbon grandfondo fork. Yes it's 1 1/8 steer tube.

It all depends on the fork design like the gentleman in a couple of posts up said.
