there's a lot of things in life that are far nicer looking and more standard that are less money than something else, but that doesn't add up to anything. As far as I know this is rare as fuck and is a curio from the late 80s when new ideas were being tried out to increase performance. As far as I know this saddle got banned at competitive level - which it was intended for - presumably because it was too effective an idea - and so have become rare as hen's teeth. NOS of this is virtually unheard of.
And some people think it's sooper dope.
Saying that, I'd ebay it myself, not sure someone will have it here, but used versions of the saddle (e.g. Corima's take on it) go for around the £80 - £100 mark on ebay on the rare occasions they come up.
I don't know this seller at all, and he's new, but I'm just getting a bit tired of people wading in with piss taking on sales threads when their targets suggest they know fuck all about what they're taking the piss out of.
tilover is allowed because he's shameless trying to sell his concor, which is rather nice.
I wish I had a memory like yours...
