I know my Sporty is no touring bike, but during my 50 mile highway ride to work each morning I would love to be able to bring a cup of coffee. Most of the cupholders I have seen are either way too bulky, or way too flimsy. I would like to find one that is not too difficult to put on and off so I can get it off there when I'm out cruising. Am I asking for too much, or does anyone have any suggestions? Coffee in my camelback will never work!
