Abstract: The present invention relates to a bicycle chainring (1) for engagement with a drive chain provided with rollers, the bicycle chainring (1) comprising: a plurality of teeth (2, 3) extending radially from a periphery of the chainring (1), wherein the plurality of teeth (2, 3) comprises a plurality of narrow teeth (3) and a plurality of wide teeth (2), wherein each tooth (2, 3) comprises a front flank (5) and a rear flank (6) with respect to a drive direction (DD) and two opposing side surfaces (9), wherein at least one side surface (9) of each wide tooth (2) comprises a protrusion (7) extending therefrom in an axial direction of the chainring (1), wherein each protrusion (7) comprises a respective groove (8) arranged halfway between a top land (10) of the respective wide tooth (2) and a root circle (11) of the respective wide tooth (2), wherein the groove (8) extends throughout the protrusion (7) in a direction substantially parallel to the top land (10).

Abstract: The present invention relates to a chain guide for a bicycle rear derailleur comprising a cage, a guide pulley rotatably mounted to the cage, a circular tension pulley rotatably mounted to the cage, and means for connecting the chain guide to a movable member of a rear derailleur so as to move the chain guide with respect to a bicycle cassette, wherein the guide pulley and the tension pulley are adapted to be engageable with a bicycle chain and wherein the tension pulley is rotatably mounted to the cage by mounting means and an interposed bearing, wherein the mounting means of the tension pulley are arranged so as to be spaced from the center of rotation of the tension pulley and wherein the mounting means are stationary in respect to the cage in the mounted state of the chain guide.

Abstract: The present invention relates to brake pad for a bicycle or a motorbike disc brake assembly comprising: a backing plate (1) having a front surface (2) and a rear surface (3), a friction pad (4) disposed on the front surface (2) or the rear surface (3) of the backing plate (1), and a backing plate extension (5) extending from the backing plate (1), wherein the backing plate extension (5) is provided with at least one cutout, wherein the at least one cutout has an inner wall surrounding the cutout, and wherein at least a part of the inner wall is provided at an inclination other than 90° with respect to the area of the backing plate extension (5) adjacent to the cutout.

Abstract: The present invention is directed to aqueous compositions with wax and graphene. These compositions offer surprising benefits in reducing bicycle or motorbike chain lengthening, particularly in off road environments with high dirt and water levels such as during mountain biking or off-road biking. The invention is further directed to a method of preparing such compositions and to the use of such compositions on bicycle or motorbike chains.

Abstract: The present invention is directed to a sensor for detecting the angle of a bicycle shoe or bicycle pedal in respect to a predetermined level and to a method of using a sensor to detect this angle. The sensor can be connected to a signaling device to notify the cyclist when the angle is less than 20 degrees such that the cyclist can lift one or both of his heels to exert more optimal power to the bicycle pedal.
