Simplified diagram of gear inches: As the rear sprocket is halfed in size, the distance traveled by the rear wheel doubles, at half the torque. Gear inches is an imperial measure corresponding to the diameter in inches of the drive wheel of a penny-farthing bicycle with equivalent ( direct-drive ) gearing.
A close-ratio transmission is one which is described relative to another transmission for the same vehicle model. The relativity applies only for the transmissions offered for a single make and model; that is, there is no specific threshold value or accepted industry standard that determines whether the steps between gears constitute a normal or close-ratio transmission.
A chain drive and rear derailleur gear change, the most popular system in use today A shaft-drive with crankset and rear gear hub. Bicycle drivetrain systems are used to transmit power on bicycles, tricycles, quadracycles, unicycles, or other human-powered vehicles from the riders to the drive wheels.
In most vehicles with a manual transmission, the driver selects gears by manipulating a lever called a gear stick (also called a gearshift, gear lever or shifter). In most automobiles, the gear stick is located on the floor between the driver and front passenger, but some cars have a gear stick that is mounted to the steering column or center ...
The average manual car driver takes between 500 ms and 1 s to perform vertical gear changes (i.e. 1st-2nd, 3rd-4th, 5th-6th) and 1 - 2 s to perform horizontal gear changes (i.e. 2nd-3rd, 4th-5th). Shift time is also dependent on gear throws (distance between gears), ease of movement, ergonomics of the gear stick , and gearbox condition.
Distinguishing it from the GM 14-bolt 9.5-inch ring gear rear differential is the latter's utilization of C-clips to retain axles, differing from the free-floating axle mechanism of its heavy-duty counterpart.
