The 8 Best threadless Stem risers (2023 reviews)

This WAKE stem riser comes with enough spacer-rings to put your existing handlebar riser at the right height and allow the stem cap and long stem bolt to fully engage. It is a forged 6061 aluminum alloy material with polished anodized finish, solid, secure, and durable. The long bolt and stem cap forces the assembled units together and down, then clamping the top and bottom riser sections together and to the bike for a solid steering connection. It extends the stem so you don't have to lean forward as far.

This riser extension is only 2.7 inches, but coupled with the top riser and raised handlebars the difference is more than 8 inches overall. It can freely adjust the gasket to fit your own height. If you don't feel like you are in control when leaning way forward to stay on your handlebars this gets the bars UP for an easier reach, several adjustments available to get just the right fit. It is long enough to add additional spacers which you can purchase separately.
