The Deus XC stem has been dramatically re-designed to minimize weight. We’ve kept the same performance enhancing features that have made our stems some of the industry’s best. However, we’ve trimmed the excess weight, making this stem ideal for high level cross country riders and racers. Features a four bolt bar clamp to hold bar securely in position and forged 7050 aluminum for high strength and fatigue resistance at a very light weight. Interlocking U-Shaped Handlebar Faceplate eliminates “stress risers” which cause your bar to bend or break–this is particularly important for carbon bar users. Thermal heat transfers and machined in logo adds tremendous aesthetic value to this high end stem. Built for cross-country.

The Thomson X4 is stronger and 30 grams lighter than the Thomson Elite 25.4 mountain stem. It features a traditional steerer clamp that is shaped to save weight and to be knee friendly. Light enough for cross-country or road. The X4 is absolutely the best combination of strength and weight available. Thomson stems are the strongest in the industry, meaning freeride and downhill riders can run Thomson confidently.
