At the bottom of the fork, fork ends hold the wheel. Usually, either the axle is bolted to the fork, or a quick release skewer passes through a hollow axle, clamping the axle to the fork. A bicycle dropout (drop out, frame end, or fork end), is a slot in a frame or fork where the axle of the wheel is attached. The term fork is sometimes also ...
Horizontal rearward-facing track fork end (not a dropout) 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 ...
Fork crown: the point at which the two blades of the fork meet below the steerer tube. Fork end: paired slots on a fork or frame at which the axle of the wheel is attached. See also Dropout; Frame: the mechanical core of a bicycle, the frame provides points of attachment for the various components that make up the machine. The term is variously ...
The rear triangle connects to the rear fork ends, where the rear wheel is attached. It consists of the seat tube and paired chain stays and seat stays. The chain stays run connecting the bottom bracket to the rear fork ends. The seat stays connect the top of the seat tube (often at or near the same point as the top tube) to the rear fork ends.
Road racing bicycle forks have an offset of 40–50 mm (1.6–2.0 in). [7] The offset may be implemented by curving the forks, adding a perpendicular tab at their lower ends, offsetting the fork blade sockets of the fork crown ahead of the steerer, or by mounting the forks into the crown at an angle to the steer tube.
The fork crown, which joins the steering tube to the fork blades, may have either an external or internal socket design. In most lugged steel frames, the lugs have a simple pointed shape. The lug's curves maximize the strength of the joint, while minimizing the possibility of stress risers , which would otherwise make the frame prone to ...
A belt-driven bicycle is a chainless bicycle that uses a flexible belt, typically a synchronous toothed design, in order to transmit power from the pedals to the wheel. The application of belt drives to bicycles is growing, especially in the commuter bicycle market, due to the low maintenance and lubrication-free benefits.
