One-handed lever control

摘要

The principle, for which a patent has been applied, of a one-handed lever control for bicycles (Patent no. 4005102.1), in which the two- chain casting-off means of a nowadays conventional bicycle derailleur can be operated with a hand lever, only about half of the gears being regarded as necessary, has been developed ready for series production. The resultant problem solutions are the subject-matter of this constitute/patent application.
