A saddle-ride vehicle includes a chain slider. The chain slider is integrally provided with an upper slider portion, a lower slider portion, and a vertical connection portion, while the chain slider has an open loop shape in which a front end portion of the upper slider portion and a front end portion of the lower slider portion are formed to be separable from each other. A swingarm has an engagement projection that is provided in a front portion of the swingarm and that protrudes outward from a surface of the swingarm. The front end portion and the front end portion engage, while overlapping with each other, with the engagement projection.

A shifting and gear assembly for a transmission has: a hollow shaft; first and second gears on the hollow shaft, the hollow shaft defining at least one first aperture and at least one second aperture in axial alignment with the first and second gears respectively; at least one first cam follower and at least one second cam follower disposed in alignment with the at least one first aperture and the at least one second aperture respectively; a cam disposed in the hollow shaft, the cam having a minimum cam contact surface having a width measured in a direction parallel to a central axis of the hollow shaft. A distance between the first and second cam followers is less than or equal to 1.1 times the width of the minimum cam contact surface. A shift actuator is operatively connected to the cam for selectively translating the cam in the hollow shaft.

A chain stay for a bicycle has: a first side wall having front and rear ends; a second side wall having front and rear ends, the second side wall being laterally spaced from the first side wall, the front end of the first side wall being forward of the front end of the second side wall; a third wall extending between the first and second side walls, the third wall defining an aperture therethrough permitting the passage of a flexible drive member of the bicycle therethrough; and a top wall connected to tops of the first, second and third side walls. At least a portion of the third wall extends downward from the top wall and from one of the first and second walls toward another one of the first and second walls. A width of the aperture is less than a distance between the first and second walls.

A shifting and gear assembly for a transmission (102) has: a hollow shaft; first and second gears (244A, 244B) on the hollow shaft, the hollow shaft defining first and second apertures (434) in axial alignment with the first and second gears; first and second shift pawls (430) disposed in the first and second apertures (434); a cam (416) disposed in the hollow shaft; and a shift actuator operatively connected to the cam (416, 512) for selectively translating the cam (416). In response to the cam (416) being axially aligned with the first shift pawl (430), the cam (416) displacing the first shift pawl (430) radially outward to engage the first gear (244A) to rotationally fix the first gear (244A) to the hollow shaft. In response to the cam (416) being axially aligned with the second shift pawl (430), the cam (416) displacing the second shift pawl (430) radially outward to engage the second gear (244B) to rotationally fix the second gear (244B) to the hollow shaft.
