I use the Ergon GC2 grips and they are a very good product. In retrospect I would have purchased the GC3 or GX3 for the longer bar ends. I don't have exceptionally large hands but I find the GC2s to be just a little smaller than I'd like. I use a bar-end mirror and there is some interference when using the bar ends. At first I tried riding with the mirror shaft in between 2 of my fingers but that was not comfortable. Now I place my hand ahead of the mirror - effectively losing some of the area where my hand would normally rest. This is another argument for longer bar ends as the mirror would likely become a non-issue. Other than that I have nothing but praise for the grips. Even with the mirror I get more hand positions and the numbness that I used to experience has been greatly reduced.
