    Reconsider what you think of aluminum.

    More recently known for their advances in the world of carbon, the engineering wizards at Zipp have shown they still know and value innovative aluminum componentry with the Service Course line. Zipp continues to impress us with its Service Course Stem, offering a highly functional design that originally addressed the needs of pros and now is available for the rest of us. It provides exceptional stiffness, lightness, and positional flexibility, but it does so at a reasonable price in comparison to more expensive, often heavier stems.

    Zipp 3D forges the Service Course Stem from 7075 aluminum. This forging process aligns the grain structure of the aluminum, giving the material strength that allows for a thin-walled final structure and smooth shaping that complements today's sculpted carbon frames. Zipp uses durable titanium TORX head bolts on the stem to provide consistent, precise torque readings, and the bolts are more difficult to strip than traditional hex-head bolts when making pre-race adjustments.

    The Service Course Alloy Stem is offered in a range of seven sizes from 70 to 130mm in 10mm increments. Each length is available in two angle options — the ±6° option is ubiquitous these days, but the ±17° models remind us of a bygone era where stems were dead flat and oh-so pro. It has a 31.8mm clamp diameter and is a perfect match for Zipp handlebars, and the 1-1/8" steerer clamp has a stack height of 41mm.

      I was very surprise by the change in design this year. Not only because of the logo but also the handlebar stem was completely redesign. I love the way it looks on my bike. The colors go great with my bike. Very happy with my purchase.
