    • The Thomson X4 Stem is stronger and lighter than their older Elite stem. A good part of this weight savings comes from the change in design. Where the Elite used an internal wedge clamp, this X4 relies on a more traditional split clamp for the steerer interface. While it meant losing the knee-saving shape on the Elite, the clamp bolts are pretty minimal given the sculpted design. The Thomson X4 Stem is CNC machined from 7000 series aluminum alloy. It has a 31.8mm clamp diameter. It's available in Black or Silver and with a zero (90) or ten (100) degree rise.
