When setting out to build the ultimate ultralight cycle touring toolkit, I first examined my old one. My old cycling toolkit was a dark and mysterious beast, I couldn’t really tell you what it contained as I rarely dug that deep.
On the odd occasion I did tip out the contents while looking for a small part I was bemused by what scattered across the floor. I knew there were several types of brake pad, five 4mm allen keys, two multi-tools and a bottle of lube in there, but there were also other more unusual things. Some I’m 70% sure had something to do with bottom brackets, others may not be anything to do with bicycles and I definitely found a bolt that belongs to my desk chair! That would never make it into an ultralight cycle touring toolkit.
