Great stem

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.

Beyond Black is the best std stem

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.

Works well

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

Solid

Been using these stems for years - just simple and solid. Weight is a wee bit pudgy 140gm for the 110mm - but great price from BTD ! )

Strong and Light

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

Not great on my super-light carbon handlebar

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.

Simply the best stem in the non-carbon game.

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!

Solid stiff good looking stem

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.
