Tandem popularity began to decline after World War II until a revival started in the late 1960s. In the UK The Tandem Club was founded in 1971, new tandems came on to the market from the French companies Lejeune and Gitane, and in the USA Bill McCready founded Santana Cycles in 1976.[3] Modern technology has improved component and frame designs, and many tandems are as well-built as modern high-end road and off-road bikes.
