S@S Couplings, Travel Bike
Shown is the S@S coupling being machined to fit the top tube , and down tube, for a nice road travel bike. This is an important process that insures that the proper interference fit between the tube and the coupler is done correctly to make the joint is as strong as possible. Machined properly also insures that the tubes are concentric with each other to insure proper alignment of the frame. More to come!
