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. Simply tighten the front bolts to lock your bars in place evenly then clamp down on the back to fully secure your bars in place. ###section### Product Specs TYPE: Top Load REACH: 49mm RISE: 34mm CLAMPING DIAMETER: 22.2mm WEIGHT: 382g
