This innovation enabled bicycle riders quickly to change gears while in motion by releasing the axle, moving the rear wheel slightly forward by applying tension to the chain, actuating the fork to change to a larger sprocket, and tightening the quick release again; or else releasing the axle, actuating the fork to change to a smaller sprocket ...
This is one of the keys to keeping the cost of this form of racing down. A chain drive system might cost around $500, whereas a quick-change rear end like those used on sprints and midgets cost upwards of $10,000. Gearing on a mini-sprint is determined by changing either the front or rear sprocket or a combination of both.
Sprint cars use "quick change" rear ends. This allows the teams to quickly change the gear ratio for different size tracks. [12] Most cars use a torsion bar suspension system. Different size bars either soften or stiffen the suspension. Torsion bars, and specialty shock absorbers are the key ingredients in the handling of sprint cars.
Quick Change is a 1990 American crime comedy film directed by Howard Franklin and Bill Murray (in their directorial debuts) and written by Franklin. [4] Based on the novel of the same name by Jay Cronley , the film stars Murray, Geena Davis , Randy Quaid , and Jason Robards .
They also are allowed to utilize quick-change rear ends and aluminum wheels, whereas the IMCA modifieds are forced to race with heavier cast-iron engines, partial stock frames, steel wheels and Ford 9-inch (230 mm) rear ends.
A fork end, [1] fork-end, [1] or forkend [2] is a slot in a bicycle frame or bicycle fork where the axle of a bicycle wheel is attached. A dropout is a type of fork end [3] that allows the rear wheel to be removed without first derailing the chain. Track bicycle frames have track fork ends, on which the opening faces rearwards. Because they do ...

When the rear end has a heavy load, the braking is not as effective. The weight is concentrated on the rear end of the vehicle, and the rear brakes need to do all of the work. When braking quickly in this situation, the front brakes will be easier to lock up because of the lack of weight transfer to the front of the vehicle. Self-levelling ...
