For all you boozehound elitist hipsters on one geared bike who enjoy a drink...Here is a tip I have. I believe it is not an original trick but I will take partial credit. The tip is quite simple. Always carry a spare folding tire for sake of stupid accidents. Now for the good part. The weight penalty serves a great purpose. Wrap the tire around your favorite 22ounce bottle of ale (no 40's damn it) and then put it in between your water bottle cage. The trick is properly wrapping the bottle. The insulation of the tire will keep the beer cool on a hot day if you are going on a short 1/2 mile run. Best of all if you have a water bottle cage on your seat tube the bottle remains upright and there is little yeast disruption!
