We carry Montague's where I work I don't own one but I have gone on a test ride with the MTB version it seemed okay I just thought it was a bit pricey for what you got. The sailboaters live them though. I noticed on the Ritchey site they have a new portable bike it isn't folding but you can take it apart and it fits into a small case. He designed it for the Airplane traveler. Has everything you would expect from Ritchey and it is definatly pricey. If I had the money I would go for the Ritchey.
