Carbon bike for commuting – concerns about durability

Asked by: Luke Schmus

What is a disadvantage of using carbon Fibre for bikes?

Disadvantages of carbon fiber bikes



They are more expensive. The cost of manufacturing with carbon is higher than with aluminum, so, consequently, its cost to the market is also higher. That is why they are specific models for the mid-high range since their spare parts are also more exclusive and expensive.

Is it easy to damage a carbon bike frame?

Hansell says, ‘It’s quite hard to damage carbon “just a little bit”, so if it looks like a crack then chances are it is a crack. ‘Also, the elasticity of carbon fibre is usually less than the paint, so if the paint is cracked, there’s a high chance there’s been some kind of trauma to the carbon too. ‘

What is the lifespan of a carbon bike frame?

Myth: A carbon frame won’t last as long as a metal one. Reality: 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.

Does carbon fiber weaken over time?

The carbon fibres used are very strong, but the resin needed to hold them together is potentially susceptible to degradation over time. Thomas Leschik, chief technology officer at Lightweight highlights this degradation as a factor which will alter the frame’s properties.

Are carbon bikes durable?

Carbon fibre is used extensively in high-tech industries from aerospace to formula one to SpaceX. It is chosen for its incredible strength, durability and low weight. All fantastic properties for building quick bikes.

Do carbon bike frames fatigue?

“Like any material, carbon fiber has a fatigue rate, just like steel or aluminum or titanium or anything,” he said. “No maintenance can keep a frame from fatiguing eventually.” In cases where Giant’s manufacturing is responsible, Juskaitis says the company will negotiate “to make things right.”

What happens if you drop a carbon bike?

Small crashes like that should not break it. Unless you fell on the frame sideways with your whole body weight and quite some momentum I wouldn’t worry. Carbon is strong, it’s hard to damage the fibers without scratching or breaking the paint (and even when the paint is damaged the fibers are usually fine).

Can a cracked carbon fiber bike frame be repaired?

Yes, you can! The process of repairing a carbon fiber bike frame that is cracked, damaged, or split is to lay new carbon fibers and epoxy them in the same direction as the original fibers. The end result is a stronger bicycle frame than the original build at a negligible weight gain.

Can you fix a crack in a carbon bike frame?

“Repairing a carbon composite frame is definitely possible but it’s a complicated process — one best performed by people with experience, knowledge and the correct tools. Original manufacturers and specialist composite bicycle repair companies are best suited to repair composite frames.”

How long will carbon fiber last?

However, some factors do influence its durability, like its matrix. Furthermore, the intense use of composites and environmental factors could affect its durability and potential applications. In general, scientists anticipate carbon fiber parts to last for over 50 years.

Is carbon fiber more durable than aluminum?

Carbon fiber is not as durable as aluminum. Carbon fiber is unpredictable, as analysis and failure results are not as controlled as they are in the case of aluminum. Carbon fiber shatters, and may crack or chip. Aluminum versus carbon fiber is cheaper, but carbon fiber is tensile and not ductile.

How do you maintain a carbon bike?

Cleaning and Washing



It’s fine to wash carbon bicycles and components like you would any other using warm soapy water and a hose. Yet, as with any bike, it’s never a good idea to aim the water directly at bearings (headsets, cranks, etc) because that can wash the grease out.

Are carbon bikes less durable?

Carbon mountain bikes are very durable in general. The power-to-weight ratio is 18 percent higher than aluminum. High-end mountain bike frames can take up to 700 KSI (kilopound per square inch) before they snap.

Are carbon mountain bikes fragile?

Durability. The myth that carbon is fragile again rears it’s ugly head, but it is just a myth. While both frame materials are susceptible to catastrophic failure, carbon fiber frames tend to be stronger per pound than their aluminum equivalents.

How long does a carbon fork last?

every 5000 cycles. Every fork will eventually break. Strong forks will last more than 10,000 cycles with a load of 270 lb.

What are the disadvantages of carbon fiber?

Disadvantages of carbon fiber composite production with hot-press forming: High costs of production implementation.



Disadvantages of carbon fiber composites:

• The biggest disadvantage of carbon fiber composites relates to its production costs. …
• Another disadvantage relates to some limitations at the design phase.

Why is carbon Fibre good for bikes?

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.”

What are the drawbacks of carbon?

Carbon dioxide gas can be toxic and very harmful to humans, It increases the temperature of the Earth’s atmosphere, It causes the global warming effect that has bad effects on the Earth.

What are the advantages of carbon Fibre?

Carbon fibers or carbon fibres are fibers about 5–10 micrometres in diameter and composed mostly of carbon atoms. Carbon fibers have several advantages including high stiffness, high tensile strength, low weight, high chemical resistance, high temperature tolerance and low thermal expansion.

What are the pros and cons of carbon fiber?

The pros of carbon fiber material is that it is lightweight, and usually stronger than regular steel AND aluminum. The cons of it are definitely the cost. The material is more expensive, because it is more labor and technology intensive. It’s gotten more affordable, but is still mainly used in luxury sports cars.

What are the three main reasons for using carbon fiber?

The main advantage of carbon fibers compared to other fibers are the high tensile strength, high stiffness, low density, and a high chemical resistance. All these advantages can be combined with an adequate (polymer resin) matrix material to give excellent mechanical properties of composite parts built from both.
