The Powerslide Nexus Trinity Frames - Rockered are available in three different lengths so that you can get the perfect length on this quick and responsive freestyle frame. They have special axles that you can turn up or down to set into rockered settings. They are made specifically for slalom skating as you can easily shift wheels of the same diameter into a banana rocker.  You can adjust each axle individually so you have a lot of rocker options.
