The meat and potatoes behind an S&S Coupler retrofit on Mike's Lemond Zurich. Ran out of time for polishing today. These couplers allow you to seperate the frame in two so that you can place an entire bike in a 26" case. The couplers, made by S&S machine are more rigid than a frame tube. Why pay oversize luggage fees, when you can pay for this modification in 2 or 3 round trip flights? My next personal frame is definitely going to have a set of these.
