This is not a saddle

This is a Selle Italia SLR Titanium Superflow saddle (in the voice of those M&S adverts ...)
"Built around a carbon fibre shell and ... titanium rails, ... weighing just 157 grams ... an ideal choice for the racer looking for long-lasting performance as well as low weight in all their componentry."
Ooh.  Shame it's incompatible with my derriere.  Happily I didn't buy it new, and maybe it'll suit my friend's Italian superbike (and his derriere).
