Shimano Di2 Button Cap for Dura-Ace R9270, Ultegra R8170 | R9250 R8150 Improve Shifting Feel

Transforms access to shifting from that button - without them activating-a shift through those buttons, particularly under stress conditions, is a virtual lottery. There are very few things Shimano gets wrong the original design of these buttons is one of them - this upgrade makes them feel like OEM equipment again. Buy them and the rest of the value from your large investment in the groupo. John

This is awesome. No more searching for the little button anymore

For something so small, it sure has a big impact! My thumbs could never seem to find the hidden Di2 buttons when I need them… until now! Buy with confidence. Love them.

Such a simple idea but so effective. Much more positive feel than the basic button, and makes it much easier to use. Will be recommending to all my Di2 friends!
