I got given a second hand bike the other day, thought it just needed some air in the tyres but turns out the back inner tube was fucked, by the end of the day I’d basically completely disassembled the thing and put it back together (including fucking Kmart selling me a tube that had a fucking hole in it). My hands were covered in grease, and the bike was back in excellent order, rode so much better.

I basically only changed a tyre, but I was out in the yard in the afternoon sun, some music playing, and at the end of the day I had something to show for what I did. Can’t recommend it enough.
