    chainslap help

    ive had my bike setup the same for a while but chainslap wasnt an issue til i moved away from the east coast now its quite deafening . im pretty new to the technical part of bikes and i wanted to know what i can do about it besides paying 50-100 bucks for a chain guide or whatnot, i want to know if theres any tricks like a shorter chain or something. my bike has a vertical dropout and a bike mechanic had to drill a hole in the chainstay to make the rear wheel fit correctly.

    A half link chain would help be giving you finer adjustment to chain length, but you would have to be lucky to get it just right. Also chains strength in time, so chainslap will get worse.

    Best option to solve the problem is to run a small chain tensioner...if you are inventive and on a budget, then you could easily make one yourself from an old derailleur pully and some cable ties.

    Simple solution to just stop the noise, but nothign else is to get some adhesive velcro strips and stick them on the chainstay, not only will this protect the chainstay very well, but it will really deaden the noise, and weighs very little.

    I would look at Yess tensioners. A lot of trials guys run them and I have heard that they give the best chain wrap and tension, which would eliminate a lot of your problems. Without horizontal dropouts, you're always going to run into the issue of chain stretch.

    Running an equivalent larger gear ratio will space the chain further away from the stay, so it won't slap. 32/18 would become 34/20 or 36/22. Keep in mind that this does change the angle of the chain and may tighten or loosen the chain tension.

    Cheeper fix:
    Just wrap an old bike tube around the chainstay and zip tie it. Chain will still slap but you won't hear it so who cares. (Ride with an I-pod blaring SLAYER to accentuate this effect) You might should do this anyway because those are some monster stays. And like sin3kal said, go with some bigger gears.

    Modestly priced fix:
    Chain tensioner

    Expensiver fix:
    EBB

    Since I imagine you are running this thing in your "Magic gear", chainstretch, which can be significant with SS's, will always be making this problem worse.

    IMHO I would go EBB. (Eccentric Bottom Bracket)

    looks like you have an iscg mounts on your bb shell, have you thought of using a blackspire stinger? a derailleur hanger mounted tensioners in push-up mode will only make your chain closer to the chainstays, by the look of it.
    everything sucks but my vacuum cleaner.
