Good morning, I went to change out my grips on my Giant Explore E+ 2 not realizing the controller is somewhat integrated into the grip and locking mechanism/coller. When i try to put on new grips the controller coller wont tighten leaving it very loose. Anyone know a way around this? I was changing to some Ergons due to arthritis in the hands. I find they help a little. The old grip has a ring of plastic that fits under the controller ring that gives helps provide a snug fit.
