    Converting a Cannondale Bad Boy to SS

    Hiya all,
    Im new here and originally posted this on the Cannondale forum so apologies for the double posting!

    I have a 2008 Bad Boy Disc and was wondering if its possible to convert it to single speed??
    Cannondale do actually make a Bad Boy SS but this has a slightly different frame with a horizontal dropout.

    I know there is tons of info around here about but TBH im finding it all a bit confusing as this is a new idea to me. If at all possible, what would be the best way of converting my bike??

    Also, as a newbee to SS would a fixed or freewheel be best??

    Many Thanks

    check up at the top-right corner of the page, where it says "Singlespeed - FAQ's - Read This First"

    going SS is pretty simple. i converted my geared bike just recently.

    first off, most will say, if not all, u should probably go freewheel/hub...

    here are a few areas you will have to focus on:

    GEAR RATIO:
    gotta decide what ratio u want to run. i think most will say 32/18 or 32/116 is a good place to start depending on what type of terrain u ride. i went 32/18 till i get stronger.

    CRANKSET:
    take off the small and big chainring and just use the middle chainring or buy a new one with the teeth# u like. if u take off the big chainring, you will need to buy shorter chainring bolts or buy a bashguard (that goes in place of the large chainring) because the bolts will be too long.

    REARWHEEL/COG:
    u have to take off your cassette and buy a singlespeed cog with spacers. something like this:
    https://www.pricepoint.com/detail/16...ersion-Kit.htm

    or you can take apart your cassette and use the cog u want and make spacers out of PVC or alike to achieve a proper chainline

    CHAIN & TENSIONER:
    you can use your existing chain or buy a SS chain like the SRAM PC-1. you will have to shorten it as much as possible so it just wraps around ur front ring and rear cog. hopefully you wont need a tensioner. if you do you can buy one like this:
    https://www.pricepoint.com/detail/16...-Tensioner.htm

    or use your old derailleur like this:


    BRAKES: looks like you have disc brakes so your good. i had to buy brake levers since i had those combo brake/shifters.

    SHIFTERS & DERAILLEURS: ditch em and sell em since you'll love SS so much you wont need them hehehe

    i think thats basically it! after that your budget is the limit. there are so many cool parts and upgrades like wheels, cranks, blah blah. but go ride and have fun!

    I hated the sette tensioner, too much tension if the chain is a bit short and its only a push down model . IF you are goign to get a spring tensioner go with the surly singulator and dont forget to get the cone wrench!

    ah, never had a chance to use the sette tensioner. it was just the cheapest on pricepoint i have the singulator and i love it.

    i installed it without a cone wrench. i took off the derailleur hanger and installed the tensioner then installed the tensioner/hanger back onto the frame. purchased it from a guy and installed it at the trailhead

    well alot of people grow to hate the sette tensioner because it simply is a very cheap quality product, I had to mod mine to get it to work decently . the cone wrench will be useful for the new surly tensioner but you gotta remember not to over tighten the spring, it will fail.
