What to Compare Before Buying
- Handlebar size: This kit is made for 31.8 mm handlebars, so the clamp size should match your bar.
- Fork size: It fits a 28.6 mm 1-1/8″ fork, so the steerer tube size matters for compatibility.
- Adjustment range: The stated ±80° angle adjustment and 110 mm maximum raise height affect how much position change you can make.
- Cable length: Longer cable routing may be needed after changing stem height or angle.
- Included spacers: Check whether the included spacer sizes work with your setup before installing.
Compatibility, Size and Fit
This stem riser is aimed at bicycles that use a 31.8 mm handlebar and a 28.6 mm 1-1/8″ fork. The stated dimensions and adjustment range make exact fit the main buying check. If your bar or fork uses a different size, this kit is not the right match.
Because the stem position changes, brake and cable length should be checked before installation. That matters any time the handlebar height or angle will be changed from the current setup.
