    bash guard on 2012 Mamba

    i got a new mamba in feb mainly to take it in the woods, i smacked it off a few logs and such and there are so many logs that i would like to get a bash guard, i asked the guy at trek how much it would be to put one on and he said he didnt think i could put one on

    basically i have never done this before and i have trouble believing that you physically cant do that, so what would i have to do to get one on my bike?

    My Trek dealer puts them on all the time. They take the top ring gear off once it is beat up. They said just chew up the top gear and once it is good and beat up swap it out with a bash guard.

    A bashguard in place of the big ring is a pretty simple affair: remove big ring, install bashguard. A bashguard in addition to the big ring, well... it's complicated. Which are you wanting?
    Worked at Trek/Fisher dealer 2008-2013. Only a little biased.

    The chain rings are not riveted on an Alivio. So putting on a bashguard is dead-simple. You could do it yourself. If you go back to your shop, try to find someone else to talk to who is more mechanically inclined. I'm thinking you must have been talking to a salesperson the first time.

    If you are ok with losing the large ring then go here, order a 32 T bashguard.
    Products

    Then get this tool.

    And do it yourself. You'll need to adjust the derailleur limit screws also, but it's very easy.

    don't forget you need to adjust the derailleur so that you can't go into the big ring

    not to bring back an old thread but is it looked down upon to get a 34t bash guard for mt 32t chainring?

    i feel like it would give a bit extra safety but reduce the ground clearance a little

    No worries at all. I would not give it a second thought.
