Man, I can't believe you guys aren't up to speed on this stuff!!!
Tam's mystery pista cranks: http://chainedrevolution.com/CS/photos/general/images/65/original.aspx are... (yur gonna slap yurselves in the forehead!)... the prototype Cobalto pista cranks that Valentino never signed off on in 1986!!!
I think the thing that threw you all was that the blue "stone" crank bolt dust covers are missing in the photos is all.
