Cycle wheel rim and method of manufacture

摘要

A cycle wheel having a U-shaped radial cross section, with two lateral sidewalls located on opposite sides of a median plane of the rim and each demarcated by an outer surface facing away from the median plane, on the one hand, and a bridge connecting the sidewalls and including an outer surface facing toward the axis of rotation of the wheel, on the other hand. At least one median zone of the outer surface of the bridge, which has a transverse width measured perpendicular to the median plane and greater than 4 mm, is machined over the entire circumference of the rim.

1. A rim for a cycle wheel, said rim comprising:
two lateral sidewalls located on opposite respective sides of a median plane of the rim and each of the two lateral sidewalls comprising an outer surface facing away from the median plane; a bridge connecting the sidewalls to one another and comprising an outer surface facing an axis of rotation of the wheel; the two lateral sidewalls and the bridge forming a U-shaped radial cross section; the outer surface of the bridge comprising a machined median zone of the outer surface of the bridge extending along an entirety of a circumference of the rim; and the machined median zone having a transverse width, measured perpendicular to the median plane, greater than 4 mm.
