I changed the Speedplay Zero cleats on my cycling shoes this morning and turned the old ones into belt buckles:
I had previously tested the buckle subframes with unused cleats, but now that they are fitted with used cleats they look a lot better. When I wear out a tyre I will use its carcass to make a belt to fit each buckle. I think they will look great with a Vittoria Corsa tubular. I want to use a tyre I have worn out as it is more meaningful than a made-for-purpose leather belt.
I like turning things which have reached the end of their useful life (so far as their designed purpose is concerned) into something useful and/or artistic.
