It is my understanding that while Cannondale has moved production of singles to Asia they have not yet made a decision on the tandems. In 2009 they made a large quantity of tandems in the US and have them boxed and ready to ship. For example our dealer told me that they have 100 bikes in our size alone in the warehouse. When they run out they will decide whether to build tandems in Asia--this according to our local dealer.
We just took delivery of a new L/S and really like it. Virtually every tube on the bike has been formed to optimize performance and comfort. It is light and stiff with a good ride. We used to own a RT2000 which was stiff and a bit harsh so were pleasantly surprised at the good ride of the RT2. This is our 4th tandem and is the best one yet. I looked at the Co-Motion Periscope Hammerhead which has an aluminum frame and good components and only weighs about 29 lbs vs the C'dale 34.6 lbs., but the difference is prices was not worth it to us.
