SIXPACK RACING Your Part Millenium Stem - Precision Engineered MTB Stem

Unleash the full potential of your mountain bike with the SIXPACK RACING Your Part Millenium Stem. Engineered for the most demanding riders and aggressive terrain, this premium aluminum stem is the ultimate upgrade for your MTB cockpit, delivering unparalleled control, stiffness, and a bold, self-confident aesthetic. It’s the pinnacle of German engineering, designed to connect you to your bike and the trail with absolute precision.

Based on our popular Millenium Stem, the new Your Part Millenium Stem with all-black look and frontal logo placement is even more self-confident and provides a functional and visual upgrade of all cockpits.The CNC-machined body with one-piece front clamp is made from 7075 aluminum not far from Sixpack´s headquarters in Germany.

The one-piece clamp wraps around the handlebar with its 213°, providing that extra handlebar clamping force and stiffness.

The stem has a clamping width of 55mm.

The stack height is 36mm.

It is available in two lengths (35mm & 45mm), with two clamp diameters (31.8mm & 35mm), each with 0° rise.The Your Part Millenium stem is assigned to ASTM category 5.

Unmatched Clamping Power and Stiffness

Experience a new level of front-end rigidity and security. The innovative one-piece clamp design is a game-changer for aggressive MTB cycling. By wrapping an incredible 213° around the handlebar, it distributes clamping forces more evenly and effectively than any traditional two-piece faceplate. This superior connection eliminates the risk of handlebar slippage under heavy impacts and boosts torsional stiffness, translating every rider input directly to the front wheel. The result is razor-sharp handling and the confidence to push your limits through rock gardens, drops, and high-speed corners.

Engineered for Aggressive, Modern Riding

Designed specifically for the geometry of modern trail, enduro, and downhill bikes, this stem puts you in the perfect attack position. The available short lengths of 35mm and 45mm provide hyper-responsive steering and a direct feel, allowing for quick line changes and precise control. The 0° rise maintains a low, aggressive front end, ideal for weighting the front wheel on steep descents and maintaining traction in fast turns. This setup is the preferred choice for gravity-focused riders seeking maximum performance.

Built to the Highest Standards

Certified for the most extreme demands of gravity riding, the Your Part Millenium stem is assigned to ASTM Category 5. This is the highest industry standard, confirming that the stem has been rigorously tested and approved for everything from aggressive enduro racing to the punishing forces of downhill and freeride. Ride with the absolute peace of mind that your equipment is built from premium aluminum and engineered to withstand the toughest conditions imaginable.
