UK Patent 661,138 - Cyclo Benelux main image

This patent covers the first Cyclo Benelux design, and is mainly concerned with the decision to off-set the pivot of the pulley cage from the line between the centres of the two pulleys. It explicitly mentions that this improves the shify by giving a more constant ‘chain gap’ - a simple fact that Tullio Campagnolo did not seem to fully grasp until 1963.
