I hope it is made better than the LET pump pulleys, they failed quickly due to the rads being too small, the bolt faces shattered as well.

Another case of the quick buck being more important than part testing, some members forgave the maker for the poor design.
Aluminum is a cheap and easy material to machine, but it is prone to failure much sooner, see the aluminum SC pulleys for more proof.
