The product is made of steel ,so it is very durable, at the same time it has holes it to make it light weight and it is very functional product.. I like it very much
There strong sprockets vortex has always been good to me the 520 don't last very long when pulling acceleration but that what's you get have to sacrifice that for acceleration 525 530 are built to last but you loose the tiny bit odd acceleration from the weight ride vortex be happy
