To the best of my recollection the bike I rode to school in the 70s (drop handlebars and (v esoteric) bar end gear levers) was generically recognised as a 'racing bike'. I was aware of the Herne Hill track a few streets away on Burbage Road (built for the London Olympics aiui) but never had the curiosity to go in and have a look (let alone 'race'). The only item I have left from it is a Brooks Competition, resurrected and used for about 20,000km last decade before retirement and in the 'never know when useful' box now.
