Carbon Vs Aluminum Bike Frames

There are four common materials used to build road bikes.

Carbon vs aluminum bike frames.

Aluminum frames possess the shortest fatigue life of any material used to manufacture bicycle frames. The main disadvantage of aluminum frame is harsher ride stiffness and also being the manufacturer is restricted on being able to control the frame flex in comparison to carbon. Conversely carbon possesses the longest fatigue life. It s worth noting that not all carbon fibre is equal and it s possible that a low grade carbon frame could weigh more than a high end aluminum frame.

Steel aluminium titanium and carbon fibre and the material can influence the ride and purpose of the bike so it s good to know the key differences before you make a decision. The aluminum santa cruz bronson frame sells for 1999 while the carbon cc version sells for 3299. Carbon frames are usually a bit lighter than aluminum up to a pound for mountain frames and up to a half pound on road frames. Ride quality is more noticeable on road frames than mountain frames with vibrations being damped by carbon more so than aluminum.

Good aluminum frame road bikes can be as lightweight as cheap carbon frame bikes. It s possible to build very light and capable bikes out of either aluminum or carbon. It s a relatively light and stiff material and generally cheaper to produce than carbon. Sometimes the choice can come down to the material the bicycle frame is made from.

Carbon fiber frames are lighter than aluminum frames because the material is less dense. That begs the obvious question is a 1 5 pound weight saving worth the extra cash. That s a 1300 difference. When it comes to the strength to weight ratio few materials can come close to carbon fiber.

In many cases bike brands will offer both aluminum and carbon frame options to fit a. Carbon however rules supreme in this area. Aluminium was the leader when it came to frame material before carbon become more accessible. The typical aluminum frame possesses a life expectancy of five to 10 years.

For high end road and racing bikes aluminum frames are a strong option when weight influences performance. Most manufacturers provide a lifetime warranty on carbon frames. The transition smuggler aluminum frame sells for 1999 while the carbon version sells for 2999 a 1000 difference. Aluminum mountain bike frames weigh around 1 pound more than comparable carbon frames.
