Is a carbon fiber MTB worth it?
For our money, the feel of carbon is superior to aluminum, and may, in fact, be worth the upgrade cost in itself. There are two major factors that we see as a benefit of a carbon frame over an aluminum one: dampening and torsional stiffness.

Are carbon Fibre mountain bikes strong?

The carbon fibres give it strength, the resin holds it together. “Carbon has the highest strength-to-weight per ply,” says Glen. “But that’s only in one direction, so it’s stacked at multiple angles in a bike frame. That means that its strength-to-weight goes down a little, but it’s still higher than other materials.”
Are carbon fiber bikes good?
Carbon fiber is a great bike material for two reasons. First, it’s stiffer at lower weight than almost any other material we know of.
What is a disadvantage of using carbon Fibre for bikes?
Flexible strength and fatigue life is the biggest disadvantage with carbon fiber. Carbon fiber is a very rigid material that doesn’t like to be flexed and bent. As well much flexing causes cracks and fissures in the structure and exposes the individual fibers which aren’t so strong by themselves.

How long will a carbon frame bike last?
Unless they are damaged or poorly built, carbon bike frames can last indefinitely. Most manufacturers still recommend that you replace the frame after 6-7 years, however, carbon frames are so strong that they often outlast their riders.
How long should a carbon bike frame last?
Carbon composite based on epoxy resin shows a very long lifetime during fatigue testing, thus there’s no degradation of the composite over the lifetime of a bike. Only long-term strong UV exposition can harm the epoxy structure, but all our frames have a UV protective agent included in the final paint layer.
How easily do carbon bikes break?
When made well, carbon fiber can be tougher than steel and quite safe. But when made incorrectly, carbon-fiber components can easily break. The parts are built by layering fibrous carbon that’s bound together with resin.
