BBB 'HIGHSIX OS' STEM 130mm 31.8 +40/-30D ADJUSTABLE BLACK ALLOY

The HighSix OS stem is a game - changer for oversized trekking handlebars. It offers ultimate freedom in handlebar adjustment. With a maximum 40 - degree upward tilt, it raises your upper body, relieving lower - back pressure. A 40 - degree downward angle gives you a sleek, aerodynamic position.

Using the HighSix OS stem is easy. First, loosen the bolts on the stem. Then, adjust the handlebar to your preferred angle, either up to 40 degrees upwards for a more comfortable, upright position or 40 degrees downwards for a more aerodynamic stance. Tighten the bolts securely once you're satisfied with the adjustment. When using, make sure the bolts are always tightened properly to avoid any safety issues. For maintenance, regularly check the bolts for looseness and clean the stem with a mild soap and water solution. Dry it thoroughly to prevent rust.
