Both quill and threadless stems come in a variety of bicycle handlebar clamp diameters. The ISO standard for the clamping area of a handlebar is 25.4 mm (1 inch), which is used on mountain bikes and many Japanese-made road handlebars. However, the Italian unofficial standard is 26.0 mm, which is the most common clamp size for road bars.
a 2006 Tete de Course, designed for road racing, with a head angle that varies from 71.25° to 74°, depending on frame size. Due to front fork suspension, modern mountain bikes —as opposed to road bikes —tend to have slacker head tube angles, generally around 70°, although they can be as low as 62° (depending on frame geometry setting).
In the days of quill stems, a road stem was clearly identifiable from its "7" shape, but nowadays it can be hard to tell the difference between a "road" (26.0 mm [1 + 1 ⁄ 32 in]) and "MTB" (25.4 mm [1 in]) stem. Manufacturers frequently omit the clamp size from advertising or packaging.
Bicycle racers seeking the greatest saddle-to-handlebar drop for better aerodynamics will often forego spacers and cut the steerer tube down to exactly match the headset bearing cup stack height plus the stem height. Cutting the steerer tube to its minimum length prevents switching to a taller stem or to a headset cups with a higher stack height.
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 ...
Fairing: a full or partial covering for a bicycle to reduce aerodynamic drag or to protect the rider from the elements; Fender or mudguard: curved pieces of metal or plastic above the tires which catch and redirect road spray thrown up by the tires, allowing the rider to remain relatively clean.
