New Fork Time

So, I bought a Trek 3700 this summer to get into the sport. Needless to say, I am addicted. Me and some friends started a club here at Penn State, and I've been riding like 2-3 times a week. Well, I think I am ready to start upgrading components and since I took a pretty bad spill that seems to have added some slop in my fork, I figure that's going to be the first thing to get swapped out. I have a few questions.

1. I have a 100mm fork on there now. Would a 120mm throw off the geometry?
2. What fork would you suggest? I am having a real tough time looking at anything else but Fox. I know they make great products (I've dealt with their shocks for Jeeps), and that white is just so damn sexy!
3. Is there anything else I should know?

Thanks a ton
Ty

Yes a 120mm fork will change the geometry and handling. Stick with 100mm.

What fork do you have on the bike now? What do you mean by "slop" in the fork? Did you crash bad enough to damage the fork requiring a replacement?

I'm not sure a 20mm difference will do that much - I went from 50mm to 80mm and only noticed the difference when doing upwards of 35mph, which doesn't happen too often, but maybe my old forks were strange and had little travel anyway.

Nonetheless, I struggle to see why you couldn't stick with 100mm - that's quite a bit of travel.

And WRT brands, I think mid range RockShox are meant to be good.

My bad, its a 4300. Idk what I was thinking...but I don't think it matters.

But yeah I am most likely going to stick with 100 unless i see a killer deal on a 120. Thanks for the help guys

Sometimes Entry level forks can have longer AC length than upper end forks. I doubt your bike would instantaniously combust by just blindly swapping forks but a simple measurement and some online homework could tell you a lot. JMO

Unless you have some experience buying a used fork could easily end up with you buying the same problem you have now. Incidentally, what actually is the problem with your fork?

It's just a cheap entry level fork without a lockout, but it makes a weird noise. I crashed really hard when I first got my bike and my fork took the entire impact (missed a bridge at the bottom of a steep hill, and went end over end a few times in/across/through a big ditch). Ever since, it's felt sloppy, and you can hear it. It's ever so slight, but I want to upgrade. It's kind of hard to explain you have to feel it...

Seems reasonable to me, what sort of riding do you do? thats going to govern what sort of fork you need.

Well, lately I have been doing alot of XC riding. I live in Central PA this time of year so it's alot of rocky technical terrain, but I do ride faster "downhill" stuff alot with jumps pretty frequently. Nothing huge, but I do love jumps haha.

I have been looking into Rock Shox alot once I realized I dont have the $$ for a fox . The reba looks killer but I don't think I will be able to swing that seeing that I would like to spend some money to upgrade other components.

I could really easily get a Tora from blueskycycling for like 150, but I would definitely spend another 100 bucks to get something a little better. The revelation looks really nice, same with the recon.

I also found a used SID on ebay with a remote lockout and a long enough steerer tube for 275 shipped, but I am not sure that's what I am looking for. The search continues! I was hoping to get money out of my savings acct. this weekend seeing that I came home from college for the weekend, but I never got a chance to get to the bank guess I'll have to wait some more. Good things come to those who wait I suppose..
