Thomson's X4 is an exceptional combination of strength and weight. Enduro and downhill riders can run Thomson confidently, yet X4 is light enough for cross country and cyclocross. X4 offers precise steering and tracking for the ultimate in control while riding. Too many modern mountain bike stems sacrifice strength and torsional stiffness for a few grams of saved weight. The Thomson X4 is the leader in strength and stiffness. The Thomson 35mm X4 stem allows you to realize the benefits of stiffer forks and stiffer 35mm bars. X4 offers precise steering, tracking, and more control while riding, all wrapped up in a beautiful design. This 35mm X4 is based on proven design and features a traditional steerer clamp that is shaped to save weight and to be knee friendly. Enduro and downhill riders can run Thomson confidently. The stem body is forged AL7050 where every surface is machined while the faceplate is forged from AL6066 and 100% machined. The X4 is built and tested to the same standards as Thomson's aerospace parts and is the perfect stem for all-around mountain biking. SM-E177.
