I am trying to figure out what gear ratio I can run on the titan frame (16.9 in. chainstays). I want to run SS with no tensioner. Since it has vertical dropouts I need to know what gears will work to give me the right tension. What have others found out? I am setting this up to be a DJ/urban bike and would like to run something around 32-36/16-18. Is there a different kind of chain I can run that will have smaller links than the standard mountain bike chain. What tricks can I use to find a setup that works besides just buying a bunch of different gear combos?
