Sand in seat stays: any ideas?
I've had some steel frames in my hands the last couple of years and they all seem have a sandish rattle in the seat stays. So I'm guessing there is sand and other small stuff, maybe even some rust going on in there. It probably came in through those tiny holes most seat stays have.
My question: did you ever notice this in your frame(s) and do you (try to) get it out of the stays. If so, how do you do it?
