This is a used SDG Ti Fly saddle.

It is black with black and silver titanium rails. 

There is one small chunk of of the over material at the back of the saddle (see last two photos).

There are a couple of small scuffs on the rails.

Other than these marks, it is still in very good condition with plenty of life left. 

Thanks very much for looking. Please check out my ebay shop for loads more bike stuff.
