Bike Stems

Strong but lightweight, Thomson stems create the ultimate riding experience. Bike stems are available for mountain biking, road biking, and BMX.

X4 : 31.8 & 35mm MOUNTAIN

Since its inception the X4 has been the best combination of strength and weight available. Constructed from one solid piece aircraft grade aluminum we didn’t sacrifice torsional stiffness or strength for a few grams of weight savings.  The X4 offers precise steering and tracking for the ultimate rider control, all while executed in an elegant design. So strong, however extremely lightweight, enduro and downhill riders can run Thomson confidently, yet X4 is light enough for cross country and cyclocross.

G2 : 31.8 Road/Gravel

The Thomson G2 features a lighter, 2-bolt handlebar clamp. The torsional stiffness and overall strength of the G2 Road stem allows you to realize the benefits of the modern stiffer forks and 31.8 bars. G2 offers precise steering, tracking, and more control while riding, all wrapped up in an elegant design.

Made in our Macon GA facility, the G2 benefits from a low 36mm stack height, and is available in a 10° positive or negative rise complete with opposing graphics.
