Ask Pinkbike: Rim Width, Angle Headsets, and Carbon Cranks
Micro-fractures are also theoretically a problem with aluminum as compared to steel. And yet we see tons of aluminum on DH bikes. When you say "carbon tends to fail", i presume that to mean in theory. There's no evidence that modern free-ride or DH specific carbon components and frames have a higher failure rate than aluminum.

Interesting that this is being downvoted. The bulk of pinkbike readers must not be ready to look at the difference between thin and thick walled carbon. My bet is that someday they will begin to make that distinction. It really is a significant difference.

fabdemaere - the strength of carbon fiber is from the carbon fiber, not the plastic bonding it together. when there is a structural failure, it is because the carbon broke. The plastic is fairly meaningless in that context. Scratched carbon only weakens to the depth of the scratch. That is the point of the whole thick vs thin carbon discussion. Matt76 - I was referring to the ultra light weight carbon bars weighing in at 180g to 200g. The renthal you mention is indeed thicker and is also almost 50% heavier. Again, distinguishing between thick and thin materials is critical. Ultra thin walled components can be ruined by minor surface damage. The same is not true of thick walled components.

josh090 - they are much lighter and stiffer for the weight. But yeah, that difference isn't worth the cost to a lot of people. I've bent an aluminum crank (spider) beyond being able to use it. I've yet to do that to carbon. Not that this proves anything.

Rampage breaks everything. But i've not heard that this actually happened. If it did, which crank model and a result of what?

I've seen aluminum cranks snapped near the pedal too. It is an interesting question... just how tough are carbon cranks. So far I've only heard (and provided) anecdotes. My observation is that there is nothing to suggest that carbon is more likely to break.

In my experience, thick carbon handles scratches just as well as aluminum. This means that carbon cranks can handle damage just as well as aluminum. It is the paper thin handlebars that you don't want to scratch or gouge. Those 180g to 200g handlebars are literally the thickness of your fingernail. The same is true of ultra-thin-walled carbon frames. But cranks? They're thick carbon. Carbon cranks are solid as hell and hold up just fine after being gouged. On top of this, they typically only get damaged from rock stikes at the tip of the crank. Plastic crank boots solve that problem. In other words, there is no evidence that i'm aware of to suggest that carbon cranks can't handle damage like aluminum cranks.

Video: Biggest Attempted Front Flip in Mountain Bike History
Looking at a photo sequence from the side you can see that he actually hit the landing just fine. He was just under rotated.

Opinion: Do You Suffer From Bike Envy?
I'm thinking the exact opposite. More durable frames and components are available now than ever before. Yeah, you can buy fragile, light-weight stuff but you don't have to.
