We use Henry James Lugs whenever possible. They are by far the smartest and most beautiful in the world.
We use silver to bond our lugs and tubes. Silver has a very low melting temperature. When a steel frame is built with silver, the matrix of the steel is left virtually unchanged and its strength unaffected. At $11 per oz., silver adds to the cost, but is well worth it.
Our tubing comes from Columbus, Dedacciai, and True Temper. The new steel alloys that are coming from these master metallurgists are more than twice the strength of a standard butted tube like Reynolds 531. This means very strong, very light steel frames are rolling out of the Vanilla workshop.
