Make Sure to Check Size

  • Familiarity: I've used it several times

I thought I ordered the right size but they were a little too small. I would recommend checking the measurements before I didn't.

easy, clean.

  • Familiarity: I've put it through the wringer

super easy to install, give a clean look and keep it clean inside.

Must have for custom builds

    I like to have a set of these on hand in the tool box when working on Di2 bikes. Always nice to have them on have for custom builds when using Di2 as well. High quality rubber, but check fit before using.

    Check fit before purchasing

      I'm sure these would work fine on the right bike, but they didn't fit my 2012 Trek Madone. Be sure to measure the hole before purchasing. They are not universal, and I have no idea what bike they fit.
