    GT Peace 9er SS chain tensioner question...

    I got my son a Peace 9er and versus fiddling with the dropouts, I'd like to get a set of chain tensioners. I bought the bike used and have no idea what size the rear axle is... 3/8", 14mm?
    What do you use?
    Would these work on the GT? REDLINE BICYCLES CHAIN TENSIONERS

    Those should work.

    The Peace 9er uses a 3/8 axle.

    NO, these will not work! The rear drop outs on the GT Peace are hooded and there is not enough space on the top of the axle for the tensioner to fit.

    I had a GT Peace and this was quite a PITA! The best you can do is to order some small screws and thread them into the tapped hole in the front of the drop out. They work similar to the Vassago Jabber nuts worked (actually the Jabber Nuts fit but Vassago has closed its doors and the parts are hard to get a hold of at this point). However, You can contact GT and find out what the thread size is or put a post out inquiring the size of the jabber nuts. Someone will know for sure (I just can't remember and I have a damn Vassago-sad I know). You can then order some stainless screws directly from McMaster Carr for a few bucks.

    I never found any other option for a tensioner that would actually fit into the dropout of the Peace and the screws were the only thing that I found to work for me.

    Here is a picture of my old set up. If you look right at the axle you can see a small screw coming thru the drop out and pushing against the axle.

    Hope this helps you out and isn't too late!

    Jabbernuts are 6/32 machine screws sold at any hardware store for probably .25c. Not sure if the GT holes are the same size but VASSAGO JABBERWOCKY front tensioners take 6/32 machine screws and it works better than those damn Jabbernutz.

    I actually haven't had a problem with my Jabber Nuts though I have heard of others having issues. So far I have been pretty happy with them.

    So I take it the Surly Tuggnuts will not work either? I had a buddy talk me out of the Redlines (good thing) and was going to order the Tugs.
    Thanks for the info guys, you are saving me some $$. Question for you on the Jabbernuts style screws... how long are they?

    I think the ones I bought (non Jabber nuts) were about 1.5" long

    Here's what I did to my Peace 9R. Had to do some grinding to get them to fit. Installed on both sides. They've been grinded alittle more since these pictures.

    I'd get the screws like 1SPD mentioned. Looks a lot cleaner and will be a lot cheaper. On my bike with track ends, I just use a rolled up towel between the rear wheel and the seat stay to set tension. But I'm a super cheap skate.
