Every day, more and more people are getting into cycling. Whilst this may be a good way to reduce the nation's obesity problems and save the planet at the same time, it's bad news for anyone who has to spend more than a few minutes listening to a bike rider bleat on and on. So You Think You're a Cyclist analyses 50 members of the cycling community, examining what makes this ever-growing tribe tick, just as keen to spend a fortune on a carbonfibre brake lever as they are to throw them selves down a hill on a freezing February morning dressed only in a thin layer of lycra. Over the following pages, a series of case studies will introduce you to some of the most common members of the cycling fraternity, giving you a glimpse into their gear-obsessed world. Starting with the newly turned cycling evangelist, this guy spent the previous 10 years slumped on the sofa with one hand on the remote control, the other shoveling snacks into his mouth.

The jury's out on whether sweat patches on your thrift store tea dress are going to go down well on the vintage style blogs.
