The term he used was “expectation differential.” I was speaking with a custom bike builder about how people react to his bikes, TIG-welded, steel creations, beautifully painted, and he said that the biggest shock for most people was how well a steel bike could ride. He said there was a huge “expectation differential” between what they think steel is like, and what it is actually like here in the 21st century.
To be clear, expectation differential is the difference between how you expect something to be and how it actually is.
Most folks last rode steel in the ’80s. They’ve been riding aluminum and carbon (sometimes Ti), and now they expect today’s steel to be heavy and clunky. Then they get on a modern steel bike and they can’t believe how well it rides. It’s not that they can’t have their socks knocked off by a new carbon fiber bike. It’s that they expect to have their socks knocked off. The differential is smaller.
Another example from my own experience is the modern suspension fork. I am a very occasional, if enthusiastic, mountain biker, so I went something like a decade (it was more actually) without updating my trail bike. When finally I did it, it was really to get to a different wheel size, rather than feeling I was going to get great benefit from a new bike.
I was wrong. Suspension forks have come a long way. First time out on my new bike, my mind was veritably blown as I floated over rock and root. I was faster, more confident, and finished the ride feeling less beaten. Huge expectation differential.
This week’s Group Ride asks, what cycling product or experience has provided you the greatest expectation differential? Where were you coming from, and where did you get to? Was it a bike? A shoe? A tire lever?
