Shimano STI Dual Control shifter and brake lever: 1. Main lever 2. Release lever A. Pulling the main lever towards the rider applies the brake B. Pushing the main lever towards the center of the bike downshifts one, two or three gears depending on how far the lever is pushed (right hand shifter) or changes from a small chainring to a larger chainring (left hand shifter)
Band brake is an alternative to rim brakes but can only be installed at the rear wheel. Coaster brakes are operated by pedaling backward; Brake lever: a lever for actuating a bicycle brake; Brake shifter or colloquially, brifter (see also Shimano Total Integration, Campagnolo ErgoPower and SRAM Double Tap): combined shifter and brake lever control
A maximum of four Blips can be used per bike. The company also took the opportunity to introduce a new shifting convention with this system. The right lever shifts the rear derailleur outboard, the left lever shifts the rear derailleur inboard, and pressing both levers together shifts the front derailleur.

Most bicycle brake systems consist of three main components: a mechanism for the rider to apply the brakes, such as brake levers or pedals; a mechanism for transmitting that signal, such as Bowden cables, hydraulic hoses, rods, or the bicycle chain; and the brake mechanism itself, a caliper or drum, to press two or more surfaces together in ...
During 1904, Frederick George Heath, Redditch, England devised and fitted a hydraulic (water/glycerine) brake system to a cycle using a handlebar lever and piston. He obtained patent GB190403651A for “Improvements in hydraulic actuated brakes for cycles and motors”, as well as subsequently for improved flexible rubber hydraulic pipes.
Road bike shifter - integrated with brake levers, sometimes known as a "brifter". [ 2 ] In 1990, Shimano introduced their Shimano Total Integration , STI, shifting levers for road bicycles, this was an indexed shifting system and the first to integrate shifting with the brake levers.
A shifter may be a single lever, or a pair of levers, or a twist grip; some shifters may be incorporated with brake levers into a single unit. When a rider operates the shifter while pedalling, the change in cable tension moves the chain-guide from side to side, "derailing" the chain onto different sprockets. The rear derailleur also has spring ...
