Trek Soho 1.0, 2008 Model need a new Fork

Hello.
This is my bike.
Trek Soho 1.0
I got it for free.... As most of the thing that are free comes with some issues. In this case it's Fork.

As you can see wheel is rubbing against that Horse shoe looking thing.
I want to buy a new fork, but i'm not sure about size i need. It says 700x32, so 700c is ~ 29", but i dont need suspension. I want to get it as cheap as possible. The Con is that the fork needs socket for front Disc Brakes.
I really don't want to spend more than 100$ just for a fork. Even 100$ I find too much for a simple fork.
And to make it more interesting, I live in Norway... It looks like it's cheaper to buy a new bike than fix old one here. But i don't want to give up so easily.
What kind of fork i'm looking for ? How to know if it will fit my wheels ?

still around where the Trek dealer is ?

you may be able to use any suspension corrected disc brake fork for 26" bikes ,
since you use the disc brakes , It does not require any V brake bosses at all and
the nature of the suspension correction is a longer distance

from the fork crown race seat to the fork tip axle center

I cannot remotely measure what that distance is off your bike,
or how far the fork tip offset is from the steering axis ,
[part of that is the fork crown offset, and the other part is the offset in front of the bottom of the fork..

but that is what determines the steering geometry . you probably want it to remain similar ..


there again a warm body at a bike shop will be better than over the internet..

Surly, A QBP brand, makes replacement forks, and there are additional brands which
ares available thru most Bike Shops, drop by and ask .

Something weird here. That doesn't happen through a fork failure. Either someone has stuck a bigger-than-intended wheel in there, or someone has replaced the stock fork with a smaller one. Which way to go with the repair pretty much depends on which it is.
Are you sure you have the right ID for your bike?
If you have, a Mosso fork off EBay should sort you out pretty close to your target cost.

I looked up the archive for that model. Comes with 700x32 tires, so I'm thinking someone has done a (improper) fork swap already.

I agree with no1mad - the fork is probably already an improper replacement. The product archive webpage no1mad cited shows a rigid fork, and the OP's photo is of a suspension fork with disc brake rotor and caliper, plus only the right-side linear pull brake ("v-brake") arm; the left v-brake arm is missing. Furthermore the v-brake pad looks like it wouldn't contact the rim if swung over - implying that fork was intended for a smaller wheel.

You can buy a 29er rigid fork that would fit from just about anywhere. As I've come to find out, almost all mtb forks and frames are fitted with disc brakes now, it is actually hard to find a v-brake fork. If you go on eBay you could find the cheap Chinese carbon forks. It isn't a bad choice. If you want name brand, you can find those too.

That's not the stock fork for that bike, looks like a 26" wheel fork.

I was looking on UK ebay and saw a used Banchi road disk fork for 10UKPounds; new hybrid disk forks for around 30. If you go with a used fork, be sure to get a long enough steerer for your needs -- a fork off a smaller bike may not fit your bike.

MTB rigid forks are often suspension corrected and inappropriate for the Soho. Closest stock Trek part would be a FX Disk fork. If you wanted to get super technical, you may be able to dig up axle to crown and offset numbers to help you out, but any hybrid disk fork will get you in the right range. Also, you need a 1-1/8" steerer.
