    Something rattling inside of sealed chainstays, making me insane

    I have a Spot brand 26" single speed, from around late 90s, early 2000s. Steel, made in Canada. There is something rattling inside one of the chainstays, but they are completely sealed. Would it be ok to drill these somewhere to either get the piece out, or fill with foam? Thanks for your help

    Frames frequently have drain or vent holes. Drill a small hole by the dropout, on the inside of the frame, and shoot a little grease in there. It should catch the little piece clanking around. No need to fill with foam (which could hold moisture).

    Stop asking how much it weighs and just go ride it.

    Idle curiosity, have you taken the BB out?

    Often times there is a hole in the BB shell near about the center of the chain stay. If so you can shake whatever is in there out. I have success with this before.

    Hi, yes, I've removed the bottom bracket. No chainstay holes. Thanks

    I had one of those Spots!

    Like others have said, 1/8 hole an inch above the dropouts, use a countersink bit for its short length and rigidity and donít go past the pilot. Then use Weigleís frame saver, itís sticky and will protect it from water that will get in and not be able to drain properly without a second breather hole. It should grab and stick to the thing thatís inside rattling too.
    But if you drill a second hole at the other end can use an air compressor to blow it out. Would be nice to know what it is in there...
