I have got my bike for almost two months now and i been using it everyday to commute to work regardless of the weather. thanks for the weather of scotland, most of the time the bike is under the ruin both when i pack it at work and on my way to/from home.

now i realised some part of my bike is getting abit rusty, e.g. my break disc, end of the gear cables, gear rings and some knobs and screws. :cry:


so what can i do to get the rust off and is there any tips to keep it "rust-less"?

  • not much you can really do, wax or vaseline will help but the best route is to replace parts that are rusting with either alloy or stainless steel parts...


    or better still titanium :twisted:

    sorry to hijack this thread a bit. But I have a similar problem.

    I have a Saracen Zen 631 which is made from steel. I've noticed a bit of brown / rust coloured water coming out of the drip holes in the frame. I'm a bit worried that the frame is corroding too quickly.

    Is this normal and is there anything I should be doing to prevent this?

    thanks Jai

    You could try this.

    Never used it myself but its supposedly very good.
  • for inside frames, waxoyl, it's a car product, and works very well, however once you have rust it is rather difficult to get rid of it. However, talking to brant from On-One, rust compromising strength isn't something to worry about.

    If you think about old steel bikes that are neglected, how many of them fail at the frame?

    i would like to not replacing any of them but then i will no longer have this problem if i replace them all..... :? the bad thing is that my shed where i keep my bike is far too small (plus no light) that i can't do any maintainence like drying the bike after riding in the ruin and so on... :(

    some people said steel wool with lemon juice can get rip off the rust. have anyone tried it?

    also, i have a service due next tuesday at Halfords (yes, i know.. but its free so nothing to lose *fingercross*), as i never have a service before what do they actually do? do they clean the bike, bleed the break/refill fluids and get the rust off the bike for me?

    thank you bogussocialworker and ride_whenever,

    I shall look into those products. I'd like to keep the frame in good nic but, sounds like its not really worth loosing sleep over.

    thanks Jai

    Depends on what service.

    Clean your bike first.

    If a 6 week check they usually check all nuts and bolts and then adjust gears and brakes as the cables will have stretched and will need re-adjusting. Some places may do more.
  • as soon as you get a new bike you should start using gt85 on it after every ride beleive me it helps they will probs have it at ur local bike shop
  • gt85 is a bit thin to do much, and if you're not careful you will get it on your discs...

    If you want to clean off rust, scotchbrite pad- sort of like a brillo pad on steroids- is the best tool for the job, but it will rust again. There's an aviation product called ACF50 which is a very long-lasting corrosion inhibitor, very good on exposed steel and alloy and available in an aerosol for abotu a tenner- it's incredibly water resistant but chemical cleaners and solvents- ie, muc off- will remove it so it's not going to last forever. I use it for motorbike use but my mountain bikes get cleaned much more often so it's not as effective.

    Someone might come along and recommend Kurust- a derusting product. DON'T USE THIS unless you'll be painting over, it does remove the rust but it comes back fast, and so degrades the metal faster than it did before the treatment.

    Now I know folks like their bikes to look good, but it IS a mountain bike. Dropped £3K on mine 6/7 weeks ago... Got in dents from stones flying up at it, scratched where my feet have caught the chain and seat stays rub on the top tube from mucky shorts....
    Yer, its a mountain bike.... 8) Rust on bolt heads is superficial at very worst, and as has been pointed out, it takes MANY years before you end up with a knackered frame from corrosion. Waxoyl drips out as well when things get warm (if they ever do!)
