Today is the day I’m sure a bunch of you have been waiting for! Profile Racing have released a bunch of videos giving us a look at all the different slack options for their Z-Coaster that has been in the works for quite a while. They have even released a video showing you how to change the slack cam ring which gives the first look INSIDE the hub since that has been top secret until now… Even the samples the team riders are on are welded sealed so they couldn’t open them! Check out the different videos below! The final video may of interest to most of us!! The Z-Coaster should be available by the end of April if all goes to plan!
