Bicycle gearing is the aspect of a bicycle drivetrain that determines the relation between the cadence, the rate at which the rider pedals, and the rate at which the drive wheel turns. On some bicycles there is only one gear and, therefore, the gear ratio is fixed, but most modern bicycles have multiple gears and thus multiple gear ratios.
Continuously variable transmission. A continuously variable transmission (CVT) is an automated transmission that can change through a continuous range of gear ratios. This contrasts with other transmissions that provide a limited number of gear ratios in fixed steps.
Beier variable-ratio gear. The Beier variable-ratio gear or Beier variator is a mechanical drive offering a continuously variable gear ratio between input and output. The gear relies on the inter-meshing of a number of thin disks. By varying their separation, the effective radius of one disk varies, thus changing the overall gear ratio.
Automotive transmissions. A hub gear, [1] internal-gear hub, [2] internally geared hub[3] or just gear hub[4] is a gear ratio changing system commonly used on bicycles that is implemented with planetary or epicyclic gears. The gears and lubricants are sealed within the shell of the hub gear, in contrast with derailleur gears where the gears and ...
A transmission (also called a gearbox) is a mechanical device which uses a gear set —two or more gears working together—to change the speed, direction of rotation, or torque multiplication/reduction in a machine. [1][2] Transmissions can have a single fixed-gear ratio, multiple distinct gear ratios, or continuously variable ratios.
Weber State Wildcats. The Weber State Wildcats are the varsity athletic teams representing Weber State University in Ogden, Utah in intercollegiate athletics, sponsoring 16 teams. The Wildcats compete in NCAA Division I FCS and are charter members (1963) of the Big Sky Conference. [2] The mascot is Waldo the Wildcat and team colors are purple ...
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 commonly used metric alternative is known as metres of development or rollout distance, which specifies how many metres a bicycle travels per revolution of the crank.
