Mid 90's GT Aggressor All Terra

[brianlap]

Hello, I am new to the forum and am rebuilding an older GT Aggressor for fun and am looking for fork replacements. I believe it is from the mid 90's. Steel or Chromoly frame.

This was the fork that I removed from the bike. It has an axle to crown length of about 380mm. It's pretty old and busted and looks to be about to kick the bucket. (not the actual fork, just a googled pic)

I would like to replace the forks with something a little stronger but I can't seem to find anything suitable. Most forks I can find online have much longer axle to crown lengths. Mostly around 480mm.

I found the following two posts from this forum. Both users look to have upgraded forks.

My question is about the difference in axle to crown length. From what I have read it's gonna change the handling of the bike. But how badly?

Does anyone have any suggestions for fork replacements? Any information would be greatly appreciated.

Hi ya Brianlap, and welcome.

might be helpful to know what year your bike is from but from bikepedia and the pic you posted of the forks its possible your bike is a 98.

the other two links you posted are of far newer GTs with newer geometry and are designed for longer travel forks so might not be a good comparison.

It looks like the original forks had about 60mm travel, quite little imo for a 98 bike when the majority of bikes seemed to be built around 80mm and even 100mm of front travel even at that time.

Any fork i reckon with 60- 80mm travel erm 390mm ish to 405mm ish A-C, would be fine for your bike , and there are plenty on here. rockshox indy xc and judys spring to mind and Z2 bombers, but it depends how much you want to spend and you need to think if you are gonna run a threaded or threadless fork coz there will be other bits that need changing.

Dont know how well it works for GT but you can compensate to some degree for longer travel forks and a slacker headtube angle by shortening the stem, so say at present you have 60mm forks and a 120mm stem, you could try 80mm travel forks with a 100mm stem without affecting the handling too much and so on.

there are plenty here who know far more , of the above forks mentioned Z2's are the best IMO
