I have a Ti subcontracted frame from Merlin through Excel Sports in Boulder, CO. They were the USA West's largest distributor of Merlin in the 90's, and had a history of running private label frames from steel to Al to Ti models. My Macalu Cirrus is from a mixed tubeset of the early 2000s Extralight. I've never gotten a first hand story regarding the details of the Macalu line. Mine was from the years when the Merlin Mass team was transitioning production to Litespeed TN. Naturally, the seller of my frameset told the story of a frame from Mass. It has the curved seat&chainstay rear-end with thick chainstays. This model has a relatively short headtube for the 59cm size. It rides small and lightning fast with a light-weight wheelset.

I will update with pics when I can find them.
