So I wanna buy a couple of freeride 530 racks.
I have Rhino Aero bars and Rola Sport.
This link here says that to use the racks with my Rola Sport bars, I need some fit kit.
Here is the 'fit kit' link
In the installation video I saw no one using bolts like this and I'm interested in knowing if I need them and what they are for
Also will this rack fit my Giant Anthem X2/Giant Talon frames & Road Bikes?
