Make Shimano Di2’s “hidden” hood buttons easier to hit, especially with winter gloves or when you’re riding hard. These slim button boosters sit under the rubber hood and increase the effective contact area of each button, so presses feel more deliberate and consistent.

Why you’ll want them

- Bigger target: easier to find and press the hood buttons without hunting for them. 
- Clean install: fits under the hood, no adhesives, and can be removed later.
- Set of 4: covers the full set of hood-top buttons (left and right lever).
- 3D printed part: lightweight, simple, and does the job.
