Well's Specialized "prototype" Tubies

While Reading a review of Well's Specialized CX rig there was mention of a "prototype" cross tubie.

Specialized tread on an FMB casing. Hmmm He raced these on Sunday to 2nd place in Portland. CX Mag says: "The front tire was a FMB-constructed tubular with Specialized tread that looked like a clipped or well-worn version of the new Captain clincher from Specialized."
