Thomson Elite 31.8 X4 Stem

The X4 starts life as a one-piece 7000 series extruded billet precision solid block of aluminum.

Our vision of the perfect stem… the X4 is the purist combination of strength, weight and CNC precision. Enduro, downhill, track racers – anyone can run the X4 confidently, it’s also light enough for cross country, cyclo-cross and road bikes.

Pair Thomson Elite X4 stems with our Elite or Masterpiece series posts, a seat post collar and handlebar for the entire cockpit collection.
