    chain tension on single speed

    hi,

    i have a single speed and there is nothing i can do to adjust the tension of the chain.(modern carbon road frame vertical drop outs) i have had a look at the chain and i can see its going to snap. so i need a new chain as i dont want to be stranded

    so i was thinking can i just put one of those tensioners on where the spindle goes through the back wheel or do i need a frame mounted one?

    do i need it to push the chain up or down?

    and lastly i have no idea what chain i have

    any answers20140813_180711.jpg

    Since you have a converted bike with a road crank, any old chain will do. KMC, SRAM work for me. You might get lucky and it fit fine, maybe you need a half link. Tensioners work fine, too. Everything easily available online most anywhere.

    I just went through this... I converted a mtb frame to ss and used a Forte tensioner kit. The flex from it being a spring tensioner kept throwing my chain alignment off when under load so I took the tensioner apart removed the spring and reinstalled it. Works great for the cost of 25ish bucks. Since it sounds like you are rigged up except for the tensioner all I can advise is to get a springless tensioner (DMR makes a good one I think), use a rigid mount of some sort. Up, down, I dont think it matters but I think up looks best.

    Okay, this is what you should have back there (this pic is a Giant OCR C3 frame)



    The derailleur hanger is the bit below the dropout with the hole in it. You'll need that to be able to mount a chain tensioner.

    OP...the butcher job that someone did to the drop-out on your bike is a shame. Thank goodness you don't mind a tensioner, hope you find one you like - you'll need it...
