The chain ring I chose

After loosing my old derailer in an accident (luckily it was only a cheap one), I used the occasion to mount the brand-new cranks and chain ring. Now I think I am riding Germany's only single-gear recumbent bike!
(New gears are already ready to be mounted, but the bike is not...)

The first picture shows how the bolt circle diameter for the new chain ring is slightly different, which is why I also bought new cranks.

Making new filters for our organic waste bin

Just like every summer our organic waste bin has become a paradise for the flies. None of us knew where to buy those carbon-fabric air filters for the bin, so I just went to the next Baumarkt and bought some large sheets of air vent filters. From that we can cut enuf garbage filters for the next decade!
