I’m in the process of trying to fix my bicycle. At some point last week, it decided that it needed more attention and proceeded to pop my back tire. You think that changing a tire would be easy. It’s not. Sort of. It’s easy enough to get it off, change the inner tube and get tire back on the wheel. The hard part is making sure the wheel is straight and doesn’t wobble and so on and so forth. I’m having some troubles with this last part. The wheel is fighting me. I shall prevail.
