Thomson X4 31.8 Bicycle Stem
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.<br /><br /><b>Product Features</b><ul style="list-style-type: disc; margin-left: 25px;"><li>Material: 7000-series aluminum</li><li>Bar Diameter: 31.8 mm</li><li>Steer Tube Diameter: 1.125 in</li><li>Length: 50 mm, 70 mm, 90 mm, 100 mm, 110 mm, 120 mm, 130 mm</li><li>Rise: 0 deg, 10 deg</li><li>Bar Attachment: 4-bolt</li><li>Weight: 174 g</li><li>Recommended Use: XC, freeride</li><li>Manufacturer Warranty: 3 years</li></ul>
