Components-Carbon vs. Aluminum

Bike parts are lighter and offer better performance than ever. The gains are largely due to improvements in material technology, such as switching from metal to carbon fiber parts. These lighter and “better” parts come with a bit of uncertainty, though. It has long been rumored that carbon parts can suddenly and unexpectedly fail if they suffer even a small scratch in a crash. We wanted to know if this urban legend is actually true and how much damage truly makes a carbon part dangerous. To find out, we sat down with the designers at one of our favorite carbon manufacturers, Renthal. This is what they had to say.

RBA: Components like bars, stems, seatpost rails or other parts can easily be damaged in a crash. Are carbon parts more susceptible to failure than alloy ones if they suffer damage?
