Here at Winterborne Bicycles we focus all of our bicycle production using one material, steel. The Metallurgists will tell you that high quality bicycle specific steels are in fact an iron/carbon alloy with the additional elements of chrome, nickel, manganese, and molybdenum. But here at Winterborne we like to wear our hats backwards so lets just call it 4130!
The method of frame construction here at Winterborne Custom Bicycle Design and Production is Oxy-acetylene Brazing. This method uses a torch and filler material to join the tubes together. Brazing allows a framebuilder a certain amount of artistic freedom that welding does not.
Fillet Brazing is otherwise known as Luggless Construction because the framebuilder is free to use any angle and any tube diameter, in other words not limited to the constraints posed on the builder by using lugs. It is also argued to be the most aesthetically pleasing of all the joining methods. A high quality fillet brazed joint gives the illusion of one tube seamlessly blending in to another.
Lugs...Beauty and the Beast
Our tube joining method of choice here at Winterborne Custom Bicycles is the timeless art, and skill of lugged construction. More bikes have been made using this method of construction than all others combined; it is a time honoured and successful way of producing a bicycle. Oh yeah and did we mention, it makes for a pretty bike that can take a sprint like nobody's business.
