Why are lugged frames better?

In most lugged steel frames, the lugs have a simple pointed shape. Lugs also reinforce the joints, often resulting in a stronger frame, this gives lugged frames in particular an advantage for touring cyclists.

What is wrong with aluminum bikes?

Aluminum is more brittle, so it’s more susceptible to failure through fatigue or damage. A single dent in the wrong place could render an aluminum frame unsafe to ride. And when aluminum fails, it fails catastrophically.

Are lugs stronger than welds?

Frames built with silver soldered lugs will last longer than those that are fillet brazed and considerably longer than those that are welded. However, for most of our customers, the real practical difference is that lugged frames hold up in crashes better, and when it becomes necessary, they are much easier to repair.

Is aluminum suitable for bicycle frames?

Titanium road bikes Very much the material of the boutique custom frame builder, the best Titanium is lighter and stiffer than steel, with a a spring in its step – it’s comfortable, light, stiff, and longer lasting than the other metals. When used to create a bike frame, Titanium is alloyed – often with aluminium.

What are lugs on bike?

Lugs, in frame building parlance, are the shapely external sockets or sleeves found joining the head, seat, top and down tubes of traditionally-made steel frames. In such frames, similar sockets are found at the bottom bracket shell and, usually, fork crown.

Why are bike frames brazed instead of welded?

“Traditionally frames have always been brazed not because a weld would fail but because the tube would fail right next to the weld due to the tube being very thin. Many bicycle tubes are heat treated to strengthen them. A square edge would create a stress point and the tube would likely fail at that point.

Can Aluminium bike frames be repaired?

perfectly possible to repair an aluminium frame. However due to the materials properties of some aluminium alloys it may weaken the frame and thus it may crack again.

Why is aluminium used for mountain bike frames?

However, aluminium frames tend to be less susceptible to crash or accidental damage than carbon frames. As a result, aluminium remains a popular frame material on all mountain bikes, as well as being a smart option for privateer road racers on a budget.
