Zipp Service Course SL Stem for Sale, Reviews, Deals and Guides

A nice lightweight stem at a good price.

A stem is a very straightforward part. Seldom does one fail do it's job, but this one does it's job while looking stylish, lean, and clean. Carbon stems have nothing on this unit. The 7-series alloy and ti hardware make it a premium part at 1/3 the cost of carbon at exactly the same modulus (stiffness). Perfect.

This is a great, high quality, lightweight titanium stem. Zipp is always a great option.

The Service Course SL is the best bang for your buck. It's reliable, strong, light weight and it looks great!

As we all know, Zipp makes some of the absolute best carbon road wheelsets in the world. They also make -fantastic-cockpit components. The "Service Course" SL is simply one of the BEST road stems made in the sport -especially for the price. Super high quality (3-D forged, aircraft grade, 7050 aluminum alloy), strong, light weight (Zipp says 135g in size 100mm) ...and... affordable. That is a combination that is hard to beat. In addition, Zipp's Service Course SL stem in their "beyond black" finish is absolutely stunning, one of the best looking road stems on the market today. This is bike jewelry. Install note: I strongly rec the use a quality torque wrench or one of Park's excellent new torque keys ($45) to tighten the bolts down to spec (6 Nm max). Don't over tighten. And you don't need to if you use a torque wrench.
