I've been out on this bike a lot more now and the bar inners have become second nature and my preferred position. I can brake and shift to the smaller cog on the right or the smaller ring on the left with the flick of a finger in the inner position. I need to move my hand to shift the other way though, but I was expecting that. It isn't nearly as hard as using bar end shifters, something I just never understood.
And the rest of the grip is really good too. It has a nice platform for you hand. But it was telling that after 10+ years of riding this bike with only the flat bar I settled into the inner position and having my hands wide on the bar felt less comfortable.
