Bicycle hydraulic component operating device

摘要

A bicycle hydraulic component operating device is provided with a main body, a hydraulic cylinder housing, a piston, an operating lever, and a fluid reservoir tank. The main body includes a handlebar mounting portion and a gripping portion. The hydraulic cylinder housing is supported by the main body. The piston is movably disposed within the hydraulic cylinder housing. The operating lever is pivotally disposed around a pivot axis relative to the main body to move the piston within the hydraulic cylinder housing in response to pivotal movement of the operating lever relative to the main body. The fluid reservoir tank is in fluid communication with the hydraulic cylinder housing. The fluid reservoir tank is supported by one of the main body and the operating lever at a location spaced from an area directly above the hydraulic cylinder housing while the bicycle hydraulic component operating device is in an installed position.
