My stem latch (the metal shell shaped piece the plastic covered stem bolt slots into when folded) is bent.
The metal is too thin. The plastic ones use to break.
As of 1 October 2008, I have just ordered new stem latches from a thicker stainless steel. The plastic ones used to break which is why we changed it. New ones should be here in a couple of weeks. - Rob English
