I have, perhaps, slightly too many bicycles. But they rarely all work at the same time. I am trying to fix this, so I can decide which ones to keep.
I keep discovering repairs I can only vaguely remember having performed. Like this brake arm on my Christiania front-loading trike. It's supposed to be fastened to the frame with a designated "brake arm clip" but I have obviously lost it, problably while changing the inner tube of the rear wheel. So I fastened the brake arm with one of my ubiquitions hose clamps.
I was probably desperate at the time, and proud when I found the solution. But I've forgotten about it completely. And it works so well, I haven't had to think about it while using it.
