i put a crank with a small chainring on my latest find. it's great for hitting the hills around here, but the bearing on the chainring side keeps getting crushed. i changed back to an adult sized chainring and crank, but the bearing on that side failed again. i'm sure i'm putting everything together in the right order, so is this maybe an adjustment problem? also, can chainrings be changed on a one-piece crank?
i enjoy riding this bike, so any help will be appreciated.
