Our vision of the perfect stem… the X4 is the purist combination of strength, weight and CNC precision, now in 35mm.
Pair with our Elite 35mm riser bars, and an Elite post or dropper for the entire cockpit collection.
The Thomson 35mm stem gives you the benefits of stiffer forks and 35mm bars. X4 stems offer precise steering, tracking, and more control while riding, all wrapped up in a beautiful design.
Fun fact, it’s certified to: CEN ISO 4210-5.
The X4 35mm uses a forged AL6066 body with a 100% CNC machined surface. The faceplate is forged from AL6066 and is also 100% machined.
Based on the proven X4 design featuring:
- Thomson CNC classic feed lines
- Durable 3mm bolts and precision matching faceplate
- All 35mm stems come in block style
Built and tested to the same standards as our aerospace parts!
