The present invention is directed to a wax with graphene compositions offering 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.

An energy chain comprising rollers on a number of chain links of the upper strand and/or of the lower strand. The rollers project, at least to a slight extent, beyond narrow sides of the lateral plates in the direction of the respectively opposite strand, in order to allow for rolling action when the energy chain is displaced. The invention provides for the rollers to comprise a wheel body made of plastic and having a hub, a rim and a radial region, which connects the hub and rim. The material thickness of the radial region is reduced in comparison with the rim such that radial impacts during the course of the rolling action can be damped by elastic deformability of the radial region of the roller itself. This significantly reduces the development of noise and vibration caused by rollers located opposite one another coming into contact with one another. The invention also proposes a roller subassembly and/or a chain link made up of two opposite lateral plates with corresponding rollers and, as a further aspect, a special way of fastening the rollers on successive lateral plates.

A bicycle chain includes a plurality of link units in series connection, and each of the link units includes two outer link plates, two inner link plates, and a pin. Each outer link plate includes two outer plate end portions and an outer plate connecting portion between to the outer plate end portions, and each outer plate end portion has a bore. Each outer plate end portion of the outer link plate has two cut portions on an edge thereof. The cut portions of the outer link plates provides a space, which is helpful to derailing the chain onto another sprocket in a low interference and a fast and smooth way.

An injection-moulded plastic part for a cable carrier, particularly a side part of a chain link produced in an injection moulding process. The injection moulded part has a visible, identifiable marking on a first side, particularly the outside. The at least one marking comprises a data code marking having a 2D code for data encoding which is introduced into the plastic body directly in the injection moulding process so that said marking is provided on the first side to be machine-readable. The invention likewise relates to a corresponding injection moulding tool having a number of first symbol regions and second symbol regions for producing the data code marking in the injection moulding process.

A hybrid chain belt which includes a toothed rubber belt and a pair of chains comprising a plurality of interleaved or laced sets of inner chain links and a plurality of interleaved outer or external links immediately adjacent the inner links mounted to the sides of the toothed belt. Each of the inner links and outer links has a pair of spaced apertures for receiving at least one pin which passes through the apertures of the links. The pins extend through the teeth of the rubber belt. Alternatively, the pair of chains may be replaced with outer links with either two apertures or a single aperture.
