I carry tools in a backpack. I lend tools to friends who don’t have what they need strapped to their bikes… 😉
You know those days when you don’t want to wear a backpack, so pop your multitool, pump, tube, wallet and phone into your jersey pockets? (Water in bottles on frame). And then the sun comes out, the world warms up by a significant amount and you decide to take your rather hefty top layer off? Can you ride alongside me to carry that layer, please? 😀
I don’t know where they came from but I have a couple of small, cheap velcro wrap things which are useful for the above, and that’s about it for me. I can imagine that other people might use them in a more imaginative way than I do.
And this:
WTF are you going to do with 30 metres of velcro?
