    Help front shock leaking?

    Hello peeps. I am a noob and I just bought a used trek 820 mountain bike. I noticed that the front shocks are leaking this weird orange rust color. Is this bad? Do i return the bike and get my money back? is it an easy fix? Do i have a LBS look at it? Please advise me someone. Thank you

    Used, from a private party. No you do not return it. It's a used bike. Take it to your LBS for a repair.

    If it is the original SR Suntour fork that came with the bike, I seriously doubt even the LBS will be able to do much, if anything with it. The "weird orange rust colour" is likely to be rust from the steel springs and insides of the stanchion tubes. Water has penetrated the fork and is starting to rust everything inside.
    Sadly, the easiest way to fix the fork is to buy another fork. Get something like a Rockshox XC28 or similar. It will be a lot better fork in the long run than what you currently have.
    I don't crash, I just have slightly uncontrolled dismounts!

    How does the fork function?


    If you feel adventures, open the fork up. Take it apart, rinse clean lubricate.

    So far I have about 50 miles on the bike. The suspension isnt leaking that color anymore. But Im just worried that It might be messed up. Is buying a new front shock worth it? Or have someone take it apart?

    The fork needs to be overhauled. While you might be able to find new seals for it, chances are good you will be unable to. Your success will depend on the brand/make of fork. A full side and front view would be helpful in this respect.

    Again, echoing what others here have said, the cheapest fix is likely to buy a new (cheap) fork.

    As others have suggested, a Rockshox XC-28 is a decent, cheap replacement. A LBS may even have something used that would work for you.

    You'll need to know your steer tube diameter (either 1" or 1 1/8") and how to remove/install the new fork. There should be quite a few threads on that floating around, but the basic gist is: remove old fork, gently remove the crown race (for re-use), cut the new fork's steer tube to the proper size, install crown race, install a star nut, install the fork, re-attach the brakes, and go ride.

    You might want to just pony up and take it to a shop for the installation, and expect to spend about $60 or so on it.

    You could put a rigid fork on it ,it would be cheeper and make the bike lighter. Would need the axle to crown measurement to get the corrrect fork.

    I had a rok shox tora or what it was called, it was the second crappiest series from the bottom. It was quite ok when it worked (not very long unfortunately), heavy with steel fork legs, steel steerer and steel springs.
    Rule #9 // If you are out riding in bad weather, it means you are a badass. Period.

    because its the original shock (RST) he said its spring loaded and the water leaking out was from when the previous guy cleaned the shock and got water inside. That being said he took it apart cleaned it and greased it and good to go. Seems fine to me after i took it on a 15 mile ride.
