The replacement saddle snapped too. It lasted from 26 January 2012 to 10 May 2012.
It snapped in exactly the same place as before but in a more dramatic fashion. I was riding up a climb when there was suddenly a loud cracking and snapping noise from the saddle. The saddle body had snapped, fortunately it was saggy but held together by the saddle cover so I was able to ride it home.
This saddle had only done 193 hours riding too, far less usage than the previous saddles before they broke.
