Ian Smith. Bicycle Wheel Analysis. [2008-12-31]. (原始内容存档于2021-04-18). I conclude that it is perfectly reasonable to say that the hub stands on the lower spokes, and that it does not hang from the upper spokes.
Tom Fine. Hubs hang from the rim!. September 1998 [2010-03-16]. (原始内容存档于2021-05-06). I still say, without any doubt, that the hub hangs from the upper spokes.
Kraig Willett. Hang or Stand?. BikeTech Review. 5 September 2004 [2010-03-16]. (原始内容存档于2010-03-11). A little known semantic debate ... has been raging on the usenet newsgroups for quite some time. The point of contention in this debate is whether or not a loaded bicycle wheel "stands" on the bottom spokes or "hangs" from the top ones?
Samuel K. Clark, V. E. Gough. Mechanics of Pneumatic Tires. U.S. Department of Transportation. 1981: 241. The system of load transmission is analogous to that of a cycle wheel where the hub hangs by the steel wire spokes from the top of the rim, which is loaded at the bottom.
John Swanson. Performance of the Bicycle Wheel, A Method for Analysis(PDF). BikePhysics.com. 2006 [2012-06-25]. (原始内容(PDF)存档于2012-09-15). Radial Stiffness: There's almost -no- vertical compliance in your wheel and people who insist that they can feel the vertical stiffness or “harshness” of a wheel are mistaken. The radial stiffness of a bicycle wheel is ~ 3-4000 N/mm. This equals a deflection of 0.1 mm under a 40 kg load. Sorry princess, but that gets obscured by the amount of deflection in the tires, fork, saddle, handlebar tape, frame, and even your gloves.
Ian. Spoke Patterns. astounding.org.uk. 2002 [2012-06-25]. (原始内容存档于2021-04-14). A radially spoked wheel is about 4.6% stiffer than a tangentially spoked one. Alternatively, if you apply 1000N (about 100kg, 220lb) to each of the wheels, the tangential (four-cross) spoked one deflects 0.0075mm (0.0003 inch) more than the radial spoked. Since the tyre is likely to deflect several millimetres at least (if 3mm, that's 400 times more deflection) I conclude the spoking is unlikely to make a discernible difference to the vertical stiffness of the wheel.
Jobst Brandt. Sheldon Brown's Bicycle Glossary: Radial spoking. Sheldon Brown (bicycle mechanic). 1981 [2012-06-25]. (原始内容存档于2007-12-18). There is no change in radial elasticity between a radial and crossed spoke wheel with the same components, other than the length of the spokes. A 290 mm spoke is 3% stiffer than a 300 mm spoke of the same type. Since spokes stretch elastically about 0.1mm on a hard bump (not ordinary road ripples), the elastic difference between the radial and cross-three wheel is 3% x 0.1mm = 0.003 mm. Copier paper is 0.075 mm thick, and if you can feel that when you ride over it on a glassy smooth concrete surface, please let me know. You have greater sensitivity than the lady in "the princess and the pea" fable.
