grrla 9 Report post Posted December 16, 2015 Hi guys!I've always wondered why the TUUK LS2 and Edge holders have copper rivets at the back instead of aluminum rivets (I think?)Also, I'm planning on replacing my Lightspeed Pro holders to Edge ones, are the rivet placements the same between the two kinds? (Size 280)Thanks in advance! :) Share this post Link to post Share on other sites
