This rule is occasionally broken where a very large number of spokes is used, or the wheel is unusually small in diameter, either of which reduces the amount of increased ...

[ 1 ] [ 2 ] [ 3 ] Although these wires are considerably stiffer than a similar diameter wire rope , they function mechanically the same as tensioned flexible wires, keeping the rim true while supporting ...
