Reading the 'How much does your commuter weigh' post got me curious as to how much stuff the average coommuter carries. I have a baisc tool kit on my bike (tube, co2 cartridges, multitool), fenders, a rack & that's pretty much it. I bring a backpack that carries my change of clothes for work & I bring my iphone & wallet. That is pretty much it for me. I see that some people have like 15 or 20 pounds of gear. My question would bem what you are packing that weights 20 pounds & is it stuff that you use regularly, or stuff that you carry 'just in case'? (Not judging, just honestly curious)
