ZippService Course SL Stem(Return to Product Page)

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

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!

Good looking stem got it to match zipp handlebars

Aside from getting a custom painted stem this stem is pretty sweet looking. The stem itself has you locked onto your bars. Ive had no problems sprinting in the drops or on the hoods.

For only a few grams more than the carbon product and a whole lot less money, gets the job done.

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.

It is really nice looking, stiff, and light weight

Zipp makes a great lightweight stem for climbing with confidence. It feels very solid when your sprinting up a hill.

90mm Zipp stem left clamp marks on my super-light carbon bar (Easton EC90 SLX) and made a squeaking sound as weight shifted. Maybe better with an alloy handlebar. Would not use again with my carbon bar. Shifted back to Easton EA90 100MM stem and bar is secure and does not squeak even out of saddle up hill with heavy pressure on bar. Now waiting to get a 90MM Easton stem so fit and functionality is perfect.

Great stem for the money! Looks sleek and cool!

This is a great stem at a reasonable price.

Very light, stiff, and uses 25 torx bolts , which I like.

Great stem - well made with outstanding bolts. Not much to say other than it does its job well. Good weight and value for price. Looks awesome as well.

fairly light and reasonably price, no problems
