  1. You overtightened it and need a new spacer. Canyon does not run classical expanders. To the other poster: It’s called a “wedge” what’s in there.

  2. expander too high or to much pressure. I crack one and even if i’ve got 2 cap for replacement, i just found a piece of plastic way thicker with the diameter of the entire tube and i put this instead.
