Shop all Thomson | Shop all MTB Stems
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 is only part of the story. 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.
