United Purge Stem. Everyone 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. United wanted to design a stem that clamped tight and evenly whilst being strong and durable so being made with fully CNC 6061 Ali block it does that and more. 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. The stem comes with a 49mm reach and a 34mm rise. Giving you the option to ditch those ugly headset spacers and tidy up the look of your bike. Available in Black or Polished.
