Flange
From WikiPedalia
A raised circular rib around a part.
- The usual use for this term in bicycle usage is to refer to the part of a hub that the spokes attach to.
- Most hubs in current production are "small-flange" or "low-flange" designs, where the flange is no taller than it needs to be to provide a suitable place for the spoke holes to be drilled.
"High-flange" or "large-flange" hubs have a larger flange, usually drilled out for lightness. They transmit torsional forces with less stress to the spokes than small-flange hubs do, but this is not a problem in practice with modern equipment. High-flange hubs can make a wheel with slightly greater lateral strength than equivalent small-flange hubs, because the spokes create a wider bracing angle to the rim. This makes them popular with track sprinters, who create greater-than-normal side loads on their wheels. - A less common bicycle use of "flange" is to describe a particular style of axle nut, commonly seen on cheaper bicycles. See track nut.
