The official price tag is 519 euros! Maybe it’s to justify the cost or to deter people from buying ATS Speed Drive, Schlumpf made this statement:
“Please notice: the internal parts were modified in order to correspond with the higher proload of the belt compared with a chain. Always ask for the original Schlumpf speed-drive made in Switzerland!”
