Abstract
A bicycle speed change lever assembly comprises a fixed support shaft, and a control lever pivotally supported on the support shaft and always subjected to a tension tending to pivot the lever in one direction. The lever has a boss portion housing a click ring formed with an arcuate series of clicking recesses. The click ring is co-rotatable with the lever boss portion. A ball is retained by a non-rotatable retainer disc in facing relation to the recess series. In one operational mode, the lever is given a rotational friction overcoming the tension, while the ball is backed up by a mode selector in a manner such that the ball comes into clicking engagement with the recess series with the capability of slight retreating movement.
