12 Myths in Cycling (1): Wider Tires Are Slower

Off The Beaten Path

When we started to publish Bicycle Quarterly 15 years ago, it seemed that most of the technical aspects of bicycles were well-established.

We’ll explain why we (and everybody else) used to believe them, and how things really work. Let’s start this series with the biggest one:
