Would I need to put a zertz insert in it before I ride?
I don't see how a missing insert could lead to it collapsing. Thanks!
I'm not sure how one would fall out, but I wouldn't risk it. It's there for suspension, and I have to believe every time the seatstay flexes, the zertz deflects the energy, absorbing the shock.
