Carbon Vs Aluminum Bike Frames

In many cases bike brands will offer both aluminum and carbon frame options to fit a.

Carbon vs aluminum bike frames.

Carbon however rules supreme in this area. 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. The aluminum santa cruz bronson frame sells for 1999 while the carbon cc version sells for 3299.

A carbon fibre frame will almost always be lighter than an aluminium equivalent and you ll only find carbon fibre bikes in the pro peloton in part because of the weight benefits. Aluminum mountain bike frames weigh around 1 pound more than comparable carbon frames. It s possible to build very light and capable bikes out of either aluminum or carbon. 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.

Most manufacturers provide a lifetime warranty on carbon frames. Sometimes the choice can come down to the material the bicycle frame is made from. That s a 1300 difference. 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. Aluminum frames possess the shortest fatigue life of any material used to manufacture bicycle frames. The density of modern carbon fiber is about 1 9 g cm 3 compared to aluminum which has a density of about 2 3 g cm 3. Aluminium was the leader when it came to frame material before carbon become more accessible.

The transition smuggler aluminum frame sells for 1999 while the carbon version sells for 2999 a 1000 difference. When it comes to the strength to weight ratio few materials can come close to carbon fiber. That begs the obvious question is a 1 5 pound weight saving worth the extra cash. 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.

Carbon fiber frames are lighter than aluminum frames because the material is less dense. A carbon frame will almost always be lighter than an aluminum equivalent. It s a relatively light and stiff material and generally cheaper to produce than carbon. Ride quality is more noticeable on road frames than mountain frames with vibrations being damped by carbon more so than aluminum.
