Thus a quill stem made to fit a 28.6 mm (1 + 1 ⁄ 8 in) steerer tube has an outer diameter of 25.4 mm (1 in). For 25.4 mm (1 in) steerer tubes the quill diameter is most often 22.2 mm (7 ⁄ 8 in) but some older American bicycles used 21.15 mm. Some older French bicycles used 25 mm steerer tubes with 22 mm diameter quill stems. [6]
Head tubes can use one of several size standards Bicycles; The head tube of a bicycle is sometimes designated by the fork steerer column it accepts. This can lead to confusion, since head tube inside diameters are dependent on the headset standard. For example, frames that take 25.4 mm (1 in) steerer columns can have three different inside ...
Frame size was traditionally measured along the seat tube from the center of the bottom bracket to the center of the top tube. Typical "medium" sizes are 54 or 56 cm (approximately 21.2 or 22 inches) for a European men's racing bicycle or 46 cm (about 18.5 inches) for a men's mountain bike.
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 ...
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.

The size of the seatpost is dependent upon the internal dimensions of the seat tube of the bicycle frame. They come in various diameters, lengths and offsets. Offset is the distance between the centerline of the seatpost tube, and the centerline of the clamp area. Shims are often available to adapt a too-small seatpost to a too-large seat tube.

Nominal Pipe Size (NPS) is a North American set of standard sizes for pipes used for high or low pressures and temperatures. [1] " Nominal" refers to pipe in non-specific terms and identifies the diameter of the hole with a non-dimensional number (for example – 2-inch nominal steel pipe" consists of many varieties of steel pipe with the only criterion being a 2.375-inch (60.3 mm) outside ...
