I've had mine well over a year and it still has no intention of cracking yet, they're decent as long as you don't go around hitting it with hammers, make sure you get a carbon protector for the thought because they're much easier to break when they're dented. As long as you're not a complete basher it shouldn't be a problem, I've go a few videos of me riding i so you know what sort of stuff it can handle.
Suppose it also depends on what frame too though, the maladies were complete poop in terms of cracking as far as I'm aware, never heard of an alaki cracking...
EDIT: BASHRING any day!
