    Abstract: The invention includes a method for manufacturing a cycle wheel rim having, in radial cross section, two lateral flanges and a bridge, the rim having an outer surface facing outward of the rim and defined by the bridge and by at least a portion of the flanges. The manufacturing method includes the following: extruding a section; bending the section; assembling the ends of the hoop formed from the section by joining one to the another; drilling holes in the bridge for fastening the spokes; machining the entire outer surface in a radial plane and on at least a portion of the circumference of the rim.

    Abstract: The driving wheel of a bicycle or moped is fitted with radial spokes for ready detection of angular divergence between hub and rim under the action of torque. The angular position of the hub is detected by means of a perforated disk having openings which pass in front of a photoelectric sensor. A hoop attached to the rim is provided with rectangular notches which also pass in front of a photoelectric sensor. The signals produced by the sensors are sent to an electronic unit for computing the torque from the time interval by which the hoop lags with respect to the disk. In addition, detection of the passage of disk openings serves to calculate the speed which is displayed together with the power obtained by electronic multiplication of the torque by the speed.

    Abstract: An aerodynamic bicycle rim, the bicycle rim comprising a circumferential clincher portion adapted to seat a clincher bicycle tire, a nose a set of sidewalls, each sidewall extending radially from the nose to a respective circumferential outer edge to form a rim body having a maximum rim body width that is greater than a maximum width of the clincher bicycle tire and spaced radially inward of the clincher portion and radially outward from a centerline of the rim body. The aerodynamic bicycle rim seats the clincher bicycle tire to form an asymmetrical cross-sectional shape in which the widest part of the rim body is spaced from a centerline of the asymmetrical cross-sectional shape and there is a tangent line tangent to the clincher bicycle tire and a sidewall of the set of sidewalls, the tangent line tangent to the sidewall radially inward from the respective circumferential outer edge.
