Carbon Vs. Aluminum Wheels
By Lexa W. Lee


Carbon fiber wheels for bicycles have some advantages over traditional aluminum wheels,
such as less vibration and greater ride comfort.
In addition, the prices of carbon wheels are competitive, as of 2010.


Vibration
Carbon in a wheel increases the strength and stiffness of the rim,
which in turn helps reduce the loss of power produced by the rider,
according to "High-Performance Composites" by Jared Nelson.
Aluminum is less stiff and more likely to wobble and vibrate
because it cannot maintain the shape of the wheel as well as carbon.

Weight
Less carbon than aluminum is needed to make a stiff rim,
resulting in lighter wheels and significantly increased rider comfort.
This is especially important in performance or racing bicycles.

Costs
The manufacture of tubular carbon rims was previously much more labor-intensive
and required more steps than aluminum wheels.
When manufacturers started making the tubes separately,
as is true for consumer-level bicycles, manufacturing costs fell.
