3T ARX Ltd Stealth Stem

3T ARX Ltd Stealth Stem is a premium ultralight carbon fiber stem engineered to provide the perfect connection between the fork and handlebar for maximum control, stiffness, and riding precision. Named after the Latin word Arx, meaning stronghold and bridge, this race-proven design has been developed to meet the demands of professional cyclists across road racing, gravel riding, cyclocross, and endurance disciplines.

Constructed from high-quality carbon fiber and equipped with lightweight titanium hardware, the ARX Ltd Stealth delivers an exceptional strength-to-weight ratio while maintaining outstanding steering precision and durability. At just 118 grams, it is one of the lightest performance stems available, making it an ideal upgrade for riders seeking weight savings without compromising reliability.

The advanced clamp design has been carefully optimized to provide a secure fit on both carbon and alloy handlebars and steerer tubes while requiring lower tightening torque values. This reduces the risk of damage to sensitive carbon components and ensures long-term cockpit integrity. Extensive in-house testing by 3T demonstrates that the ARX clamp system significantly exceeds CEN safety standards while maintaining excellent compatibility with handlebars from multiple manufacturers.

Finished with sleek 3T Stealth graphics, the ARX Ltd combines elite performance with a refined, professional appearance.
