  • Machined from 7000-series aluminum; the stem is a 1-piece design with no welds or joints
  • New steerer clamps save about 20g of weight
  • Wide clamp length (48mm) and patent pending undercut around the handlebar combine to grip the handlebar more securely; provides a stiff ride with minimal flexing or squeaking
  • Steerer tube clamps have a large surface area and go around the steerer tube more that 180° 2 bolts provide and extra level of security
  • Center tubular section is tapered with a constant wall thickness, resulting in a high stiffness-to-weight ratio and torsional rigidty
  • Annodized to maintain a nice appearance and prevent corrosion
  • Thomson logo is applied with a laser, so it will not rub off; laser marking process is specially designed to maintain the integrity of the anodization

  • X4 is engineered to work very well with both carbon handlebars and carbon steerer tubes
  • Every component of the stem, including the fasteners, is 100% American made
