2. Bicycle wheel - Wikipedia

   en.wikipedia.org/wiki/Bicycle_wheel

   The formerly popular 27 inch (630 mm) wheel size is now rare. Children's bicycles are commonly sized primarily based on wheel diameter rather than seat tube length (along the rider's inseam) dimension. Thus, a wide range of small bike wheels are still found, ranging from 239 mm (9.4 in) diameter to 400 mm (16 in).

3. Spoke - Wikipedia

   For example, a 32 spoke wheel has 16 spokes per side, 360° divided by 16 equals 22.5°. Multiply 22.5° ("angle between adjacent flange holes") by the number of crossings to get the angle a—if 3-crosses, the 32 spoke wheel has an angle a of 67.5°. Regarding r 3: The size of the spoke holes in the flange does not matter for the needed spoke ...

   The correct length of spokes required can be calculated using rim diameter, hub flange diameter, hub width, lacing pattern, and number of spokes. See [ 2 ] and. [ 3 ] [ self-published source ] These calculations can be done either by hand (the old-fashioned way - with a pen, paper and calculator) or by using a computer.

6. Spoke nipple - Wikipedia

   en.wikipedia.org/wiki/Spoke_nipple

   Nipples 12 and 16 mm. A spoke nipple holds a bicycle wheel's rim to each spoke. The spoke nipple is a headed cylinder with threading on the inside through part of its length (there is an unthreaded lead-in nearest the "flats"). Traditionally, the nipples fit in holes in the rim, so that the head of the nipple is on the outermost part of the rim ...

7. Gear inches - Wikipedia

   en.wikipedia.org/wiki/Gear_inches

   For example, consider a 700c × 23 mm tire, which has a nominal cross-section of 23 mm. 700c wheels have a rim diameter of 622 mm. Hence the wheel diameter is (2 × 23 mm) + 622 mm = 668 mm which is equal to 26.3 inches (rounded to 1 decimal place). 26 inch mountain bicycle wheels have a rim diameter of 559 mm. This ignores factors that ...

8. ISO 5775 - Wikipedia

   The inner width of the rim on which the tire is mounted should be about 65% of the tire's nominal section width for tires smaller than 30 mm and 55% for those larger. The section height of a tire is usually identical to its section width (for tires less than 28 mm, 2.5 mm have to be added to the width to get the height).

9. Wheel sizing - Wikipedia

   en.wikipedia.org/wiki/Wheel_sizing

   Another setup option of staggered wheel fitment is called double staggered, having smaller diameter narrow width wheels in the front with larger diameter and wider width wheel in the back. For example, a vehicle may feature 18 in × 8 in (460 mm × 200 mm) wheels in front and 19 in × 10 in (480 mm × 250 mm) in the rear.
