Ergo Shifting
Campagnolo ErgoPower is an integrated gearshift and brake lever system designed by Campagnolo for racing bicycles. It allows shifting gears without having to remove a hand from the bars, unlike previous down tube shifting systems. It was launched in 1992 to compete with Shimano Total Integration (STI). It is characterized by having three separate levers per unit: one each for braking, upshifts, and downshifts. Ergopower levers may be disassembled for servicing. Details ErgoPower levers contain the mechanism inside the main body of the unit, rather than in the top of the brake levers as STI does, and there is no sideways action on the brake lever. Instead, the "flipper" that changes to a smaller cog on STI levers changes to a larger cog, and there is a small lever (sometimes called a 'mouse ear') on the inside of the brake hood body that shifts to a smaller cog.

Campagnolo Centaur Ergopower Shifter - Rear View
Campagnolo is an Italian manufacturer of high-end bicycle components with headquarters in Vicenza, Italy. The components are organised as groupsets (gruppi), and are a near-complete collection of a bicycle's mechanical parts. Campagnolo's flagship components are the Super Record, Record, and Chorus groupsets with all three representing their recent shift to 12-speed drivetrains. Super Record and Record are the top groupsets, followed by Chorus, Potenza, Centaur and Veloce. Campagnolo also produces aluminum and carbon wheels, as well as other components (like carbon fiber seat posts, and bottle-cages). History Founded by Tullio Campagnolo, the company began in 1933 in a Vicenza workshop. The founder was a racing cyclist in Italy in the 1920s who conceived several ideas while racing, such as the quick release mechanism for bicycle wheels, derailleurs, and the rod gear for gear changing. Campagnolo has been awarded more than 135 patents for innovations in cycling technology. A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shifter (bicycle Part)
A bicycle shifter or gear control or gear levers is a component used to control the gearing mechanisms and select the desired gear ratio. Typically, they operate either a derailleur mechanism or an internal hub gear mechanism. In either case, the control is operated by moving a cable that connects the shifter to the gear mechanism. Location Traditionally shifters were mounted on the down tube of the frame or stem. For ergonomic reasons, they tend to be located somewhere on the handlebars on modern bicycles. Mechanisms There are various types of shifter: * Grip shifter - a wheel with click stops surrounding the handlebar is turned until the desired gear is reached, though typically one gear at a time * Trigger shifter - a lever is pulled or pushed to change gears one at a time * Thumb shifter * Road bike shifter - integrated with brake levers, sometimes known as a "brifter". In 1990, Shimano introduced their Shimano Total Integration, STI, shifting levers for road bicycles, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bicycle Brake
A bicycle brake reduces the speed of a bicycle or prevents it from moving. The three main types are: rim brakes, disc brakes, and drum brakes. 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 order to convert, via friction, kinetic energy of the bike and rider into thermal energy to be dissipated. History Karl Drais included a pivoting brake shoe that could be pressed against the rear iron tyre of his 1817 . This was continued on the earliest bicycles with pedals, such as the boneshaker, which were fitted with a spoon brake to press onto the rear wheel. The brake was operated by a lever or by a cord connecting to the handlebars. The rider could also slow down by resisting the pedals ...

Racing Bicycle
A racing bicycle, also known as a road bike is a bicycle designed for competitive road cycling, a sport governed by and according to the rules of the Union Cycliste Internationale (UCI). Racing bicycles are designed for maximum performance while remaining legal under the UCI rules. They are designed to minimise aerodynamic drag, rolling resistance, and weight, and balance the desire for stiffness for pedaling effiency with the need for some flexibility for comfort. Racing bicycles sacrifice comfort for speed compared to non-racing bicycles. The drop handlebars are positioned lower than the saddle in order to put the rider in a more aerodynamic posture. The front and back wheels are close together so the bicycle has quick handling, which is preferred by experienced racing cyclists. The derailleur gear ratios are closely spaced so that the rider can pedal at their optimum cadence. However, racing bicycles must retain the ability to maneuver safely within a tightly-packed pe ...

Down Tube
A bicycle frame is the main component of a bicycle, onto which wheels and other components are fitted. The modern and most common frame design for an upright bicycle is based on the safety bicycle, and consists of two triangles: a main triangle and a paired rear triangle. This is known as the ''diamond frame''. Frames are required to be strong, stiff and light, which they do by combining different materials and shapes. A frameset consists of the frame and fork of a bicycle and sometimes includes the headset and seat post. Frame builders will often produce the frame and fork together as a paired set. Variations Besides the ubiquitous diamond frame, many different frame types have been developed for the bicycle, several of which are still in common use today. Diamond In the diamond frame, the main "triangle" is not actually a triangle because it consists of four tubes: the head tube, top tube, down tube and seat tube. The rear triangle consists of the seat tube joined by p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shimano Total Integration
Shimano Total Integration (STI) is a gearshift system designed by Shimano for racing bicycles. It combines the braking and gear shifting controls into the same component. This allows shifting gears without having to remove a hand from the bars, unlike previous down tube shifting systems. This component is usually referred to as a "shifter (bicycle part), shifter" or "dual-control levers", or occasionally "brifters". In late 1989, Shimano introduced their "Rapidfire" shifting for mountain bikes. This brought indexed shifting to the handlebars - something previously only available on downtube shifters or thumb shifters. This mechanism operates like a ratchet, the larger lever applying tension to the gear cable, the smaller one incrementally releasing it. The Rapidfire mechanism was subsequently adapted to be used in STI levers. In 1990, Shimano introduced their STI shifting levers for road bicycles, which completely integrated the brake lever and shifter. It also redesigned the ...

SRAM Double Tap
SRAM Double Tap is an integrated gearshift and brake lever system designed by SRAM Corporation for racing bicycles. It allows shifting gears without having to remove a hand from the bars, unlike previous down tube shifting systems. It was launched in late 2005 to compete with Shimano Total Integration and Campagnolo ErgoPower. It is characterized by having a single shift lever per unit that the rider moves inward a short distance for upshifts and a longer distance for downshifts. It is lighter and smaller than competitors because it has few parts. In 2010 SRAM expanded the Double Tap technology from the original drop handlebars to flat handlebars on flat bar road bike A flat bar road bike, also called a fitness bike, is a hybrid bike optimized for road usage or a road bike with a flat handlebar in place of a drop bar.
