I was excited to take the stupid child trailer adapter off my bike. Having a nice light bicycle and then attaching a pound to the rear axle made me sad. The cheapest and biggest gains on a bicycle are definitely in the rider for the vast majority of people.I remember having a similar conversation with a friend who was trying to justify spending mega $$$ on a new racing bicycle to save a few ounces.
I suggested just not having the extra bagel at breakfast...
