Product Description

The design team for the new Thomson 31.8 stems had a tough goal: make a stem better than the Thomson Elite Road and Mountain Stems. Early tests showed us that our competitors? 31.8 stems were heavier and weaker than Thomson Elite 25.4 and 26.0 stems. At Thomson our new stems were not done until they were stronger, lighter and longer lived than the legendary Thomson Elite.The new Thomson X4 for Mountain and X2 for Road allow you to realize the benefits of stiffer forks and stiffer 31.8 bars. They offer precise steering, tracking, and more control while riding, all wrapped up in a beautiful design. 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.

If you want strength, stiffness and reliability...Buy a Thomson bicycle stem!...I have been mountainbiking for 15 years and I have found the Thomson aluminum stem to be an excellent stem when "weighing" strength vs. weight vs. durability...All my race bikes use Thomson stems - light enough and very confidence-inspiring with the 4-bolt front plate...'nuff said...Ride On!
