Zipp beautifully balances weight savings and strength with Service Course SL Stem. The 100mm version tips the scales at just 125 grams thanks to a 3D-forged 7075 aluminum construction which also yields incredibly stiff performance and exceptional durability.

I bought this stem in the 130 mm. to put on my 2021 Trek Checkpoint ALR 5 that came stock with a 110 mm. stem. I am 6 foot tall with longish arms and wanted to be stretched out a little longer. BTW, the 20 extra mm. comes to around 3/4 of an inch, or .79 to be exact. I installed in the negative 6 degree position which still has a little rise but less than the positive 6 degree. This changed my position for the best and made for a little racier bike that my original setup....As for the product itself, It looks spectacular. Bigger, with sublime graphics that I love.... In fact, I loved it so much that several months later, I did my whole cockpit with ZIPP.... Stem, plus Bar & Tape, & seatpost. I love it.... Of course we are talking aluminum here, but all for less than 350$.... But the stem is definitely the highlight.... Do It.
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.
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.
