The chain guide extends from the mounting bracket along a path of the drive chain, and preferably includes an upper guide having an inner barrier positioned inboard of the bicycle chain an outer barrier positioned outboard of the inner barrier and an upper barrier positioned above the bicycle chain for preventing the chain from derailing from the chain ring in an upward direction.

Abstract: In a brake system including a master cylinder and an electrically-driven hydraulic pressure generator with front and rear pistons, when the hydraulic pressure generator cannot be operated and a failure of a first hydraulic system linked to a rear fluid chamber of the generator occurs and makes a first hydraulic system open to the atmosphere, the brake-fluid pressure of a second hydraulic system transmitted from the master cylinder to a wheel cylinder via a front fluid chamber of the generator is used to perform braking. A forward-facing third front cup seal provided at an intermediate portion of the front piston prevents the brake-fluid pressure generated by the master cylinder from leaking out from a front supply port via the rear fluid chamber. At the same time, a stopper prevents the pressure of the front fluid chamber from moving the front piston excessively backward. The braking is accordingly secured by use of the second hydraulic system linked to the front fluid chamber of the motor cylinder.
