I've got a 2001 Marin Portofino made by Billato Bros. with Columbus Foco tube set. I was wondering if that was a standard tubeset that Billato used to produce all frames during that time period?
Marin’s top of the line steel frameset features Columbus Foco tubing. This tubeset is heat treated and offers superior strength at a very light weight. The Portafino comes equipped with a carbon fork, and features triangulated seatstays and box section chainstays. This frame is treated with a rust proofing coating called “Cataphoresi”. This electronic dipping process coats both inside and out with an epoxy finish. This treatment adds an extremely minimal amount of weight to the frame and negates the need to use a primer coat while painting.
