The DATE STAR-AHEADx1 is the basic BMX handlebars compressor which provides basic compression when you upgrade your fork or handlebars.
It is compatible with all the forks that have the "tube neck" without thread inside. Original MATE X forks have such a threaded neck, therefore a threaded compressor nut should be used in those cases. However, pretty much everything else nowadays is using straight or tapered fork tubes without a threaded neck.
