Just cause I want to. I'm a bartender at a ski resort, I don't have any bills, I rarely buy gas, I live in my van, I eat rice and beans, I don't drink or smoke, I'm not married. In return I have a full ice climbing/mountaineering/backpacking setup, multiple pairs of skis and snowboards, etc. I was born and raised in Flint Michigan and didn't have nice things when I was younger. I'm just playing with my toys before my body starts to give up. I don't really have a parts bin, I just donate or sell what I'm not using.
Fair dinkum, I mean CKs look nice so I can't blame you and I do have 2 of them currently and am considering one for a new bike build.
Rice and beans are also quite good, you season everything right and life is good.
I couldn't do the no parts bin thing but I get it, van life is awesome but offers little space for a parts bin.
However you have a nice looking bike so you did it well : )
