Toe Clip Straps

I've mentioned before that I don't care for toe clips on my pedals. I feel any performance advantage they give is offset by the inconvenience and increased potential for injury compared to clipless pedals or regular flat pedals.

However, the straps that are used to tighten the toe clips are just about the handiest thing out there. They can be used as a general-purpose tie-down for all sorts of things. For example:

Making a u-lock holster in a front basket

Also handy for keeping wine bottles from rolling around

 Or securing a musical instrument case so it can't bounce out of a rear basket

The mandolin is worth five or six times what the bike is, I DON'T want it flying off if I hit a pothole. 

You can also wrap a spare inner tube and a tire lever up in a rag, and use a toe clip strap to attach the bundle to the underside of your saddle, to make a minimalist flat repair kit, complete with a rag to wipe your hands on (assuming you've attached your pump somewhere else).

In short, these things are handy. My preference is to scrap the clips themselves, but save as many of these as you come across.
