I also have the GP3s on my hybrid and really like them. I recieved these as a gift and never really thought that I would utilize the little bar ends, but now every time I get on a bike without them it just isn't the same. Sometimes when going up a steep hill or really getting on it at an intersection I put my hands on them slightly similar to the way you would the hoods on drop bars and it seems to help with the momentum of getting going (this could very possible just be in my head though...). I could never imagine needing the super long bar extensions that you see a lot of people using, but these are just enough to move your hands around a bit and relieve some of the built up tension caused by a long ride. If nothing else they do make for a good coat rack to hang stuff on.
