Nieuwe stuurnok van Thomson voor lefty en headshok vorken

Lefty® & Headshok™ X4 : 31.8 Mountain


The Thomson Elite X4 Stem for Cannondale® Lefty® and Headshok­™ forks grew from the legacy of the Thomson Elite stem. A great all around modern stem to fit 31.8mm diameter handlebars. Finally Thomson is a choice for Headshok­™ and Lefty® riders.


This is the first Thomson stem to fit the popular Cannondale Lefty and Headshok fork. This stem is built for forks that have a steerer tube. Some newer Cannondale Lefty equipped bikes have a one piece stem/steerer tube assembly and this stem is not for such bikes. All the benefits Thomson X4 stem riders have enjoyed on 1.125″ forks are now available to Cannondale riders. Torsional stiffness, steering precision, long life, and that Thomson machined look. 

The Thomson X4 stem allows you to realize the benefits of stiffer forks and stiffer 31.8 bars. X4 offers precise steering, tracking, and more control while riding, all wrapped up in a beautiful design. 

Certified to: EN 14766 2006 MTB and DIN CERTCO: 2006 MTB 

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. 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.
