Nice collection of product info.
I too attended Interbike many times, as both a vendor and a dealer.
I always made note of the useless products, the money and effort put into them
and the presentations to try and sell them.
There are many, but my all time favorite useless item was the
Inclinometer. Small plastic tube, similar to a carpenters level, mounted next to a scale.
This thing was mounted to the top tube of the bicycle.
As you rode, the small ball in the tube would indicate the slope you were currently riding at.
First, the thing was difficult to read, especially while riding.
Second - who cares!
Sorry, no photo at this time.
