What is a lugged bike frame

A lugged bike frame is a type of bicycle frame construction where the tubes of the frame are joined together using metal lugs. Lugs are essentially metal sleeves that fit over the ends of the tubes, and are then brazed or welded in place. This type of construction was popular in the early days of cycling, and is still used today by some manufacturers who specialize in traditional or retro-style bicycles. Lugged frames are known for their elegant appearance and the ability to create complex and intricate designs. However, they are generally heavier and more expensive than other types of frame construction, such as welded or monocoque frames.

Parts of a Lugged Bike Frame

A Lugged Bike Frame is made up of several pieces. They fit together with metal sockets (lugs) at each joint point. This holds the tubing in place.

The Rear Triangle consists of two Chainstays connecting the Rear Dropout and Bottom Bracket Shell. Plus two Seat Stays from the Top of Seat Tube to the Upper part of Rear Dropout.

The Fork holds the Front Wheel and takes in road vibrations. The Saddle and Seat-post give riders comfort while pedaling.

Lugged bike frames have been around for over one hundred years. Materials like stainless steel, titanium, or carbon fiber are used now.

Ritte’s Snob bike was made with Italian Columbus XCR lugged steel. Tom Kellogg and Sean Walling from Souther California-based Soulcraft made it.
