I need to change my Shimano Deore brake pads soon. I was thinking of trying out the Kool Stop brakes. Went to the Kool Stop website to check out the goods. Now, I'm confused.....which brake pads should I get for my Deore brake set-up (which are V-brakes, right?)? Better to get the whole pad assembly, which, according to my research, would be the threaded type? Or do I just get inserts (or is that at all possible)?
