S&S stainless steel Bicycle Torque Couplings for a frame using OS tubing (28.6mm top tube, 31.7mm down tube) would add 0.6 pounds (275 grams) to the weight of the bike. That's not much of a weight penalty for the flexibility it provides in carrying along a full size 700c wheel bike in a 26" x 26" x 10" S&S hard case that meets the 62 linear inches for airline checked baggage without incurring oversize baggage surcharges.

Salsa tech support says the weight of the stainless steel Vaya travel bike with S&S BTCs is lighter than the chromoly version without S&S BTCs.
