Some friends of ours (tomorrowhillfarm.com) have 2 sets of Seven bikes with S&S couplers. First they had steel road bikes made. They took them to Europe a few times.
This spring they had ti bikes made with wider tire clearance. They just took them to France for 5 weeks and rode some nasty gravel roads with them.
The road bikes have carbon forks and the ti bikes have steel Waterford forks. They prefer the ride of the steel forks now.
Some other people I know wanted S&S coupled bikes to take to Italy this year. They got Surly Travelers Check frames. These are about $1200 retail, but they found some for $900 each. I have seen some come up on ebay from time to time.
