EVERY ONE KNOWS THAT RE-SETTING YOUR BARS IS THE WORST POSSIBLE THING. IT TAKES FOREVER FOR YOUR MIND TO AGREE THAT THE BARS FEEL HOW THEY DID BEFORE SLIPPING. WE WANTED TO DESIGN A STEM THAT CLAMPED TIGHT AND EVENLY AT THAT. WE HAD SEEN STEM BOLTS SNAP FROM A ROCKY PLATE AND UN-EVEN TIGHTENING. WITH THE PURGE STEM WE WANTED STRENGTH AND DURABILITY SO WE WENT WITH A FULLY CNC 6061 ALI BLOCK INCLUDING A CNC’D UNITED GRAPHIC ON THE SIDE. YOU WILL NOTICE THE CLAMPING SYSTEM CLAMPS COMPLETELY SHUT UP FRONT. THIS IS TO STOP THE UN-EVEN TIGHTENING.
