The Zipp Service Course SL Stem (in Beyond Black) is my personal favorite when lusting for aluminum. Super stiff, lightweight, and dependable. AND... it looks damn good!

Installed on wife's Cervelo S3 - no issues. Looks good.

Well it's a stem. Plenty stiff, solid, and lightweight. Does require a Torx key so make sure you have one in your toolkit when riding.
Does cost a bit more and it's a stem. But IMO, the stem helps the look of the bike.
The beyond black matches the bike well so I got to give it 4 stars.
