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.

Frequently asked questions

Is your question is not listed? Contact us HERE. We will do our best to get back to you within 24 hours.

Will these fit my shifters?

They’re intended for Shimano 12-speed Di2 road levers like Ultegra R8170 and Dura-Ace R9270.

Do I need tools or to remove my bar tape?

No tools needed. You just roll the hood forward, place the boosters, then roll the hood back.

Will they cause accidental presses when I change hand position?

The idea is to make presses easier while still requiring a deliberate push. Button sensitivity depends on your hood position and how you rest your hands, so do a quick test ride after fitting.

Do they interfere with the rubber hood sitting flush?

They’re designed to sit under the hood without bulging. If your hood doesn’t sit flush, remove and re-fit, and make sure the part is aligned in the correct spot.
