Bicycle rim brake

摘要

A bicycle rim brake basically has a first brake arm, a second brake arm and a link. The first brake arm has a first coupling portion configured to pivot about a first pivot axis and a first mounting portion. The second brake arm has a second coupling portion configured to pivot about the first pivot axis and a second mounting portion. The second mounting portion is configured to mount a second friction member. The link is pivotally coupled to the second brake arm about a second pivot axis that is offset from the first pivot axis. The link has a coupling structure configured to be coupled with a movable member and a contact portion contacting the first brake arm. The coupling structure is spaced from the second pivot axis. The contact portion pivots the first and second brake arms about the first pivot axis as the link pivots about the second pivot axis.
