aluminum cranks

My friend, who’s very knowledgeable in unicycles, told me that aluminum cranks are pretty weak, and that he bought some that broke within a week. What I want to know if it’s really true that they are weak, and if I should look into some other cranks. Thanks!

depends what kind of riding you do

Also depends what kind of crank is in question. KH Moments are aluminum. They’re extremely hard to break.

Maybe your friend is not so knowledgeable?

Bot much?
