A derailleur gear selection mechanism for a bicycle having front and rear derailleur mechanisms.
The front derailleur may include an attachment mechanism for securing the derailleur to a bicycle frame member.
The object of the present invention is a bicycle derailleur, especially a rear derailleur, used to change the transmission ratios of gear wheels.
A shifter for a bicycle having a derailleur, comprising a housing adapted to mount to a handlebar of the bicycle.
A bicycle transmission shifting device that includes a cable (20) having a portion of the cable attached to a derailleur and also having another portion of the cable attached to a cable drum (22).
The system (10) includes a fluid actuated shifter mechanism (14) for shifting a drive chain laterally to select different sprockets on a derailleur gear, particularly a rear derailleur gear.
The invention provides a derailleur gear shift system (10) for a bicycle.
The handlebars are used for steering and as hand operated pedals being directly connected to crank gears and derailleur gears.
An adjusting device for cables, especially bicycle cables, used to control gears, brakes, derailleur gears and the like.
A bicycle derailleur gear shifting system having a rotatable handgrip actuator coupled with a derailleur shifting mechanism through a control cable system so as to control the derailleur.
In certain embodiments, the tool includes a derailer (22) for placement between the tire (26) and wheel (28), an extension arm for selective deployment of the derailer into the tire, and a wand (34) for deployment form the derailer.
But this will lead to problems with the drivetrain and to collision of right heel and rear derailer (unless you have a Rohloff 14 gears SpeedHub).
Internal gear hubs are more reliable than derailer systems, and require much less maintenance.
Isn’t it better to triumph by the strength of your muscles than by the artifice of a derailer?

Watch where the batter is standing in relation to the plate.
The reliability and performance of the GranSport rear derailleur were further enhanced with the introduction of the Record rear derailleur, in 1962.
However, all types of gear, except a front derailleur can be used (rear derailleur and gears in the hub).
Remember, overdubbing was forbidden by the union at that time.
I'm perfectly capable of changing my own bandage, thank you.
In addition, the use of the derailleur is less important.
