The most preposterous gadget award goes to the Sogreni Bicycle Trouser Clip, a hand-milled bit of aluminum with a silicone band that will set you back $25 whole dollars. Of course, it is shipped in a timber box filled with wood shavings, so as to protect the fragile aluminum rod.
I have to admit, though, that Sogreni makes some lovely bikes.
