Rohloff AG

Later he struck out on his own and founded Rohloff AG, where he first invented an advanced narrow chain that soon became the industry standard for road-bikes and was used by several Tour de France winners, and the manufacturing methods therefore. He personally designed "the green beast", a proprietary machine for manufacturing SLT-99 chains.[3] Rohloff AG became an OEM chain manufacturer for Campagnolo.
