When I was a kid, everything I had was the wrong size. Bikes way too big, shoes too large, pants too big. I was supposed to grow into them.
When I got that little Peugeot, I was only 9 y/o and I couldn't even stand over it. Had to learn to ride on a bike that I couldn't straddle. By the time I finally grew into stuff, it was all beat up.
I promised myself that, if I could afford it, my kids would get stuff that fit. I can afford it, and better yet I like - and my kids also like - used stuff, which is called "vintage" now and cool, doncha know, so I can even better afford it, without feeding the disposable consumer crap machine. I don't mind building my son a vintage bike that will only fit him for a couple of years. He'll be taller than me so this won't be his last bike.
Wonder what the next will be? We could keep doing the vintage steel with modern bits theme. I've got a '61 Specislissima sitting in the basement, wonder how that would look with Di2? Just a thought, just a thought.
