Carbon Versus Aluminum Bike Frames

While both aluminum and carbon bikes will offer a little bit of flex in this way carbon bikes will offer a far greater amount of power.

Carbon versus aluminum bike frames.

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. Ride quality is more noticeable on road frames than mountain frames with vibrations being damped by carbon more so than aluminum. Carbon fiber frames are lighter than aluminum frames because the material is less dense. Most bike frames will be made of either steel titanium aluminum or carbon fiber steel and titanium are the most popular options for custom and handmade bike building.

Great road bikes for under 1 000. Carbon fibre can be relatively easily manipulated by designers to create frames with the particular balance of properties they want whether that s low weight comfort stiffness. That s a 1300 difference. These are kind of a novelty at this point.

Conversely carbon possesses the longest fatigue life. Aluminum frames possess the shortest fatigue life of any material used to manufacture bicycle frames. For more info check out my carbon fiber vs aluminum frame guide. These joints are similar to carbon fiber.

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. This means more speed more enjoyment and more confidence while you re riding. Aluminium was the leader when it came to frame material before carbon become more accessible. Having said that bamboo is a legitimate bike frame material.

The vast majority of modern bikes however will be made from aluminum or carbon fiber. 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. This means carbon bikes feel much faster while accelerating and will be much more responsive when setting off. Buy carbon if you want the lightest and stiffest road bike money can buy or because you want to go aero.

Most bamboo bikes are made by starting with strong bamboo poles then binding the joints together with fiber and resin. The transition smuggler aluminum frame sells for 1999 while the carbon version sells for 2999 a 1000 difference. 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. That begs the obvious question is a 1 5 pound weight saving worth the extra cash.

It s a relatively light and stiff material and generally cheaper to produce than carbon. Most manufacturers provide a lifetime warranty on carbon frames.
