Freezing mechs?

Anyone else have the problem of freezing mechs whilst riding in these conditions?

What do you use to sort them out? Will some de-icer spray used for windscreens etc be ok?

    Defrost, water dispersant (such as WD40 or GT85) and then lube them, if they are lubed water can't get in....

    Cables are more likely to freeze than mechs.....

    The problem I had was on Friday it was bloody cold and I was out for a ride. The snow was gathering in the spring on my rear mech which was freezing solid. Also there was a lot of snow gathering in and around the front mech which was doing the same.

    Better than mud gathering there but they were freezing solid. I was giving them a spray with GT85 but it wasn't shifting.

    Would de-icer work better? Then give them a spray with GT85 afterwards?

    I tried that but the ice inside the spring on the rear mech was frozen solid...

    Apart from pissing on it... Where do I get hot water from in the middle of the woods? lol
  • If your spring is frozen you are going to struggle to sort it out on the fly.

    As others have suggested when home defrost, clean and lube but consider using a small amount of grease on/in the spring with the housing lubed as normal. This will not stop the snow getting into the spring housing but should keep it off the spring and stop the snow compacting and turing to ice in the spring body.

    Seems to work pretty well with my MTB.
    Pain hurts much less if its topped off with beating your mates to top of a climb.

    Single speed... If it freezes solid wait till you get home and defrost.

    Hot water/Urine just makes it worse when that refreezes...I guess a can of screen de-icer would help, but plenty of lube to stop it sticking in the first place.....that and let the bike get cold before you ride so it's not warm and melting the snow to let it refreeze.

    Once it's frozen you have to let it thaw before you can fix it.

    Blast with WD40 then oil with something heavier.

    Shifters are vulnerable too.
