Abstract
A gearshift for bicycle gears includes an operating lever arranged so as to be rotatable around a stationary central axis for controlling an operating part arranged in a housing. The operating part is also rotatable around the central axis and has a take-up groove for receiving a gear-shifting cable, whereby a latch interacts with a tooth mechanism on the operating part for winding the cable. The gearshift further includes a release-and-hold mechanism consisting of a first latching disk having a first latching segment and a second latching disk having a second latching segment connected to the operating part, and of a release lever that interacts alternately with the first latching segment and the second latching segment. Arranged on the release lever are a first latching lug and a second latching lug, which alternately engage with the first latching segment and the second latching segment. The release lever is mounted pivotally about a rotational axis arranged substantially perpendicularly relative to the central axis in a stationary fashion. An advantage of the invention lies in the simple operability of the operating lever and the release lever, whereby attention has been given to the ergonomics of the lever that the bicycle gear can be shifted under any circumstances, even when the operating hand of a bicyclist is being used for operating a brake lever.
