Cogset: the set of rear sprockets that attaches to the hub on the rear wheel; Cone: holds bearings in place, pressed against the cup; Cotter: pin for attaching cottered cranks; Coupler: to connect tubing together; Crankset or chainset: composed of cranks and at least one chainring
Chainrings (also called "chain rings", [11] "chainwheels" or "sprockets", although sprocket is used this way mostly in the BMX community [3]) engage the chain to transfer power to the (usually rear) wheel. They usually have teeth spaced to engage every link of the chain as it passes over; however, in the past, some designs (called skip-tooth or ...
There is some disagreement as to whether the word axle or spindle should be used in particular contexts. The distinction is based on whether the unit is stationary, as in a hub, or rotates, as in a bottom bracket. [2] American bicycle mechanic and author Sheldon Brown uses axle once and spindle four times in his bottom bracket glossary entry. [3]
Q factor is a function of both the bottom bracket width (axle length) and the cranks. Bottom brackets axles vary in length from 102mm to 127mm. Mountain bike cranks are typically about 20mm wider than road cranks. [6] A larger Q factor (wider tread) will mean less cornering clearance (while pedaling) for the same bottom bracket height and crank ...
Front/rear gear measurement uses two numbers (e.g. 53/19) where the first is the number of teeth in the front chainring and the second is the number of teeth in the rear sprocket. Without doing some arithmetic, it is not immediately obvious that 53/19 and 39/14 represent effectively the same gear ratio.
This can give information about the distribution of axles. For example, provide manufacturers the chassis configuration 8×4×4 to show that the vehicle has two steered front axles and two driven rear axles, compared to the chassis configuration 8×4/4 where the vehicle has one steered front axle, one steered rear axle (the fore axle) and two ...
A swing axle is a simple type of independent suspension designed and patented by Edmund Rumpler in 1903 for the rear axle of rear wheel drive vehicles. This was a revolutionary invention in automotive suspension, allowing driven (powered) wheels to follow uneven road surfaces independently, thus enabling the vehicle's wheels to maintain better ...
The twist-beam rear suspension (also torsion-beam axle, deformable torsion beam, or compound crank) is a type of automobile suspension based on a large H- or C-shaped member. The front of the H attaches to the body via rubber bushings , and the rear of the H carries each stub-axle assembly, on each side of the car.
