I've had a coupla Mutants and they look about like a half flacid (or half erect I guess depending on if you are an optimist or a pessimist) penis.

I've got a 90mm Titec stem I used to run on my Pista. It's dark grey instead of black but if you're interested I'd sell it to you cheap as I got rid of the bike and a 1" threadless stem is pretty much useless. PM me.
