    15/17 fixed/fixed?

    is it possible to run a fixie/fixie setup on a fluip-flop hub with a 15t cog on one side and a 17t cog on the other or would that require a tensioner?? I'm not particularly fond of tensioners and would prefer to avoid using one, by the way I don't have horizontal dropouts.

    Thanks in advance!

    I think a two tooth difference could be taken up by sufficiently long horizontal dropouts, which you don't have. I think your only other option is the ENO hub. Don't know how much adjustment that has, but it costs a good bit more.

    Do you have vertical dropouts? I have a feeling that you actually do have horizontal dropouts, but you are confusing that term with track ends. Pics please.

    Not without long horizontal dropouts:

    You would need .5" usable dropout space for it to work.

    That picture is of a pair of track ends, not horizontal dropouts.

    False. Two additional teeth are equivalent to 1" of additional chain wrap or about 1/2" difference in the location in the dropouts/ends. If they were off by a single tooth, then you would be correct.

    Track ends are a subset of "horizontal dropouts."

    ^Fail. Track ends are not dropouts.

    OP, can you post a pic of your dropouts/track ends?
    I'm not one for fawning over bicycles, but I do believe that our bikes communicate with us, and what this bike is saying is, "You're an idiot." BikeSnobNYC

    Picture please.

    And I'm somewhat amazed by the amount of fail contained in this thread.
    It's bad when you're 19 and people consider you an "old geezer" in the current FG community.

    Two teeth add only 1/2" of extra wrap because the chain only goes around half the cog. Divide in half again because of the chain going from cog to chainring twice to get 1/4".

    Or read http://www.sheldonbrown.com/fixed.html#flipflop (1/8" per tooth)

    You'll need a White Industries ENO hub.

    Ok, so just to add fuel to the fire...what about NON-vertical drops using a chain-tensioner? I have a flip-flop hub & have thought about adjusting the gearing & have seen pics/posts regarding the goodspeed chain tensioner...

    Is this crap? Am I showing how new I am? Or just missing something? (and yes there are other options & a combo available).

    Are you running fixed? If yes, then you can't run a tensioner. If single-speed, then yes.
