Great stem!

The Tall-Stack is a fabulous stem that does just what it's supposed to do: replace an unsightly stack of spacers and give you a little leeway to run a slightly taller set-up without a using an "upright" stem. It's clean, smooth, and shiny, with an elegant single bolt at the front. I couldn't be happier.

Very Clean

I bought a 110mm stem in Noir. It's a real beaut. Thanks V/O

Tall-Stack Stem, 31.8mm

Gorgeous stem but a bit noisy

I absolutely love the aesthetic of this stem. It brings a clean and classic look to a build and does a great job of making some extra stack above the headset look tidy. However, the stem creaks quite a bit. I am going to try using a longer bolt on the steerer tube to see if that does the job, but it’s a persistent annoyance. I’ve fully removed the stem and cleaned it multiple times, and while that temporarily quiets the creaking it always returns. I’ve never had this issue with more conventional stems with 2-bolts on the steerer tube. Still love it but wish this issue would be addressed!

Tall stack stem in noir

Beautiful & functional stem that puts you in a more upright position but with a traditional & classy look. All for a reasonable price. I couldn't be happier with it.
