An arrangement for actuating a shift element for a bottom bracket gearbox (1) includes a shift ring (4) rotatably mounted in a housing (3) and assigned to a gearbox component. A shift pawl (5) for locking or releasing the shift ring (4) is assigned to the shift ring (4) for shifting a gear stage. A support region mechanically reinforces the housing (3) and is provided at least along a contact region (14) between an inner wall (8) of the housing (3) and an outer circumference of the shift ring (4). The contact region (14) is defined by reaction forces (16) acting when the shift ring (4) is locked.
