Blade

Sheldon Brown's Bicycle Glossary · letter B
← Blackwall Tire · Block →

One of the two "tines" of a front fork.
A spoke that has been flattened in the direction of rotation for improved ærodynamics. "Bladed" spokes are so wide that they will not fit through the spoke holes of a standard hub flange. The usual solution to this problem is to file a notch or two to enlarge each spoke hole. This is very labor-intensive, and risks creating a stress riser which can lead to flange failure.
