If you excuse the bad mudflap waffling, the saddle on my bike here is a stripped SMP Extra. I couldn't make it work on there but took a punt with it on my pompino and it's going great
I had to remove the screws and file down the points that had come through the top shell, otherwise its good to go. There's a small amount of give to the shell too so it's not rock solid.
