Video: Two wheel rims take a heavy beating. Was carbon or alloy strongest?

This carbon rim was given a beating, as was its alloy counterpart. The results of this video experiment might surprise you.

 

It may not be the most scientific experiment ever, but the results are still interesting.

The guy in the clip below sets out to test how robust carbon wheel rims are in comparison to their alloy counterparts.



Carbon has a reputation for being light but breaking easily. And while repairing broken carbon is by no means impossible, it is difficult.

Most riders would trust a carbon frame repaired by a reputable craftsman, but few would chance a rim that had been repaired.

And once carbon rims break, that’s a lot of hard earned money up in smoke.

But the test below – using mountain bike rims – suggests the commonly held view that carbon is much more vulnerable does not really hold true.

As we’ve said; this is by no means a scientific experiment.

But it shows the aluminium rim does not stand up to very much pounding.

The carbon takes a beating much better, and according to those who made the clip the carbon rim had already been replaced because it was starting to deteriorate.
