    Where can I find a chain tensioner like this and whats it called? (Pics)


    Where can I find it?
    What type of chain tensioner is this called?
    Will this be useful for a frame with no hanger?
    Thanks!

    You don't want to use that. I tried the Kore on my first SS MTB (2000 I think, before I found this place) and it never worked. Back then it was $50. They are designed for downhill applications. Not SS.

    Is the frame damaged? I think at that point an ENO hub or a magic gear are your only choices.

    If you rummage enough, you'll be able to find a slide-in mount that will make a derailleur hanger appear where there once was none. It's how they mounted derailleurs on frames like that way back. Then you can just get a normal tensioner.

    Or you could just get a bolt-on axle and turn it into a reggalar-ol' singlespeed. What's the situation where you need a tensioner even though you have semihorizontal dropouts?

    Well you see. There is too much slack still on my chain, and it can easily come off the chainring and freewheel if i hit a bump or something. but i can't remove another chainlink or else it'd be too short. so i guess a chain tensioner is the way to go.

    Any decent bike shop should have a half link on hand for less than $2.

    If you have the above style of dropout then a half link is your best option.

    Why do you need a tensioner if you have horizontal dropouts as you describe?

    this...


    our co-op has probably 30 of these, plus another 40 on bikes, i'm SURE if you go to any bike shop or co-op in san fran, they have some stuffed somewhere.
