This shot is lifted from the flickr stream of Robert, aka ‘paris-roubaix’. Click on the photo to go through to his flickr if you are interested in Scottish Cycling history or vintage road bicycles, there is a wealth of great stuff there.
Here’s a 1954 front cover of the old Scottish Cycling magazine. Pictured are the Wallacehill Cycling Club having a drum-up. No Chryston Wheelers type fire. A bit more sophisticated, they’re using a Primus stove.
