当编得很好的钢丝辐条轮承受径向负载（如车手坐在自行车上）时，车轮与地面接触处附近会略有凹陷，其余部分则基本保持圆形。 所有辐条的张力都没有显著增加，轮毂正下方的辐条张力还有所降低。 对如何描述这种情形存在争议。 有人认为轮毂“站”在正下方那根张力减小的辐条上， 还有人认为轮毂“挂”在正上方那根张力较大的辐条上。

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?"

"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]. "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]. "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."
