how to tell if carbon bike frame is cracked | EWIG

No matter how experienced an eye is cast over a frame, some levels of damage are simply invisible.Your ears, though, may be able to tell you more.Carbon usually has a very crisp sound to it [when tapped] and when it’s damaged the tone changes completely.

 Do carbon bike frames crack easily?

The best carbon bike frames are strong, lightweight, comfortable and responsive. Most road cyclists are looking for the strength of steel and the weight of titanium. Carbon fiber offers the best of both worlds: a featherlight frame that’s durable and stiff. Making it the material of choice for racers around the globe.

As long as you don’t crash hard or take a hammer to the frame, a carbon bike can theoretically last forever. In fact, steel and aluminum last only so long before the metal fatigues and can no longer be used safely, but carbon remains stable indefinitely.

Carbon fiber is five-times stronger than steel and twice as stiff. Though carbon fiber is stronger and stiffer than steel, it is lighter than steel; making it the ideal manufacturing material for many parts.

All carbon fibre material used in cycling must be bonded in some regard, usually with a two-part epoxy resin. Most frame manufacturers build frames with sheets of carbon fibre that is pre-impregnated with uncured resin.

Durability is one question. A crash that might scratch the paint on a steel frame could cause significant, hard-to-repair damage to a carbon frame. Since carbon fiber frames are generally more rigid than other materials, these stresses can lead to structural failures while in motion.
