FR Skates Brake Assembly For 4 Wheel Frames

I needed a heel break for my Seba Trix 2, to be able to attend a inline instructors course. The Seba heel breaks seem to be no longer available, the only pair I could find online where with an Australian store and shipping costs ruled them out.I noticed an article that mentioned the FR breaks, so decided to give them a try. They fitted like a dream and the Seba Trix2 have selectable height adjustment on the front and rear wheels to allow for rockering. The FR breaks come with a bolt that allows you keep the rocker setting you desire.They seem pretty solid but I have not skated using it yet.
