To ensure lifht weight and high stiffness of frameset,We use our R625 butted tube to make the frameset ultra light-weight while keep high stiffness.Our TSUNAMI CR03 is most likely the lightest and strongest steel framese you can find in the world.Welding vs.Brazing Bike Frames Mission BicycleWhat Is Brazing?What Is Welding?What's on The Street?Which One Is Better?What About Us?A filler metal (like brass or silver) is heated just above its melting point and distributed over two adjacent tubes.As the filler metal cools it hardens and forms a joint connecting the metals.Brazing uses a filler metal with a melting temperature lower than the frame material.So the filler melts to connect the tubes,but the tubes themselves don't get hot enough to change.It's a bit like gluing two pieces of paper together.The papers don't change but are joined as one.See more on missionbicycleTaxi&- Jamis&BikesStarting with the lightweight aluminum frame and a parts pick thats nearly all lightweight alloy parts.The results are bikes just north of 30 pounds that are easy to pedal and more fun to ride. sloping top tube design,alloy kickstand,and painted steel chainguard welded seat collar with chromoly QR Alloy pillar style,26.8 x 300mm
