Sometimes called a goose neck, [1] a stem's design belongs to either a quill or threadless system, and each system is compatible with respective headset and fork ...
Note that, on a bicycle, as rake angle increases, head angle decreases. Trail can vary as the bike leans or steers. In the case of traditional geometry, trail decreases (and wheelbase increases if measuring distance between ground contact points and not hubs) as the bike leans and steers in the direction of the lean.

[14] [16] The steerer had to be cut to the correct length in order to adjust the height of the stem. [14] MC3 was a third version that was only the stem, thus the handlebar was not welded. [14] Klein held a patent (US 5433465 ) for an improved method of routing cables through the frame of a bicycle, that reduced aerodynamic drag and stress on ...
Gear inches is one way of measuring the gear ratio(s) of a bicycle, so that different gears and different bicycles can be compared in a consistent manner. 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.
Kickstand: a folding attachment used for assisting a bicycle to stand up on its own.

A single-speed bicycle is a type of bicycle with a single gear ratio and a freewheel mechanism. These bicycles are without derailleur gears, hub gearing or other methods for varying the gear ratio of the bicycle.
When sizing a fork to a frame, the diameter of the fork steerer or steer tube (1″ or 1⅛″ or 1½″) must not be larger than that of the frame, and the length of the steerer tube should be greater than but approximately equal to the head tube length plus the stack height of the headset. Adapter kits are available to enable use of a 1 ...
