Weight Reduction by Removing Shock?

Hi, Experts--

The bike I'm talking about here is a 1994 Specialized Hardrock FS (hereafter known as "beater") equipped with SR Duotrack 7001 front shock/fork.

I'm a lightweight, so it's hard for me to really test, but my impression is that this shock/fork does not provide any shock absorption at all; and it's just extra weight to drag around. Also the new Cascadia fenders look weird zip-tied to the sides of thosa fat tubes.

Against my better judgement, I'm contemplating replacing this "shock" with a Surly front fork:

This will require new threadless headset, etc, etc.

Can anybody tell me a ballpark estimate of how many pounds lighter the bike would be after such a modification?

Thanks for your help!

Bikes: I never learned to ride a bike. It is my deepest shame.

Ballpart estimation of weight loss: 1lb. The surly forks are pretty... um... surly. They about as chunky a fork as you can get. You might save 2 lbs or more if you get a truly light fork.

Suspension forks are generally around 4 lbs, rigid forks are between 1.5 and 2 lbs, and surly forks are between 2.5 and 3 lbs.

Also, if your suspension does not seem to be doing anything, it might be because it is not doing anything - suspension forks need regular maintenance - lubrication and cleaning - to keep them working, and it is common for older forks to turn into heavy rigid forks.

IMO lower end shock forks also degrade the handling of the bike by adding play into the front end. The shock probably does absorb some vibration, but you can also just run tires a bit lower pressure. Since you're running fenders, I assume you're mostly riding on road. If so, I think swapping to a rigid fork is probably a good idea. But I wouldn't worry too much about weight on a bike like this. Crisper, cleaner handling will be the bigger benefit. I wouldn't waste money on anything super light. Just get a basic cromoly replacement fork.
