The present invention is directed to compositions with solvent, 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.

A transfer case having a chain drive disposed in a housing. The housing defines a vent aperture and a sump. A lubricating fluid is disposed in the sump and portions of the chain drive travel through the lubricating fluid so that a lubrication surge zone and a splash lubrication zone are formed. The vent aperture is disposed in at least one of the surge zone, the splash lubrication zone and the sump when the transfer case is disposed in at least one orientation in a predetermined range of operating positions in which the transfer case can be operated. A breather relocation conduit is employed to permit air to be vented from the housing to the vent aperture without intaking lubricating fluid into the breather relocation conduit.

A chain guide for a bicycle having may include a base frame and a height adjustment member connected to the base frame and slidable relative to the base frame and lockable in a first position by engaging a first locking member. A retaining member may be pivotally connected to the height adjustment member and may be pivotable about a pivot axis a retaining position, in which the retaining member is positioned to obstruct lateral movement of the chain away from the chainring thereby preventing lateral misalignment between the chain and the chainring, and a removal position, in which the retaining member does not obstruct lateral movement of the chain away from the base frame while the height adjustment member is locked in the first position. The pivot axis may be spaced apart from the first locking member.

A crank arm comprising a crank arm receiving portion, a sprocket, a sprocket guard comprising a sprocket guard receiving portion, a nut engagable with a bolt fixing the sprocket to the crank arm receiving portion, and a third fastener engaging the sprocket guard receiving portion through the bolt.

A device is provided for protecting, allowing cleaning, servicing and/or lubrication of one or more components of a bike or vehicle in use. The device is formed from at least one blank of material including a first portion arranged to act as a shield element so as to at least partially shield at least one component of the vehicle or bike in use, and at least a second portion. The second portion includes at least one wall joined to the first portion by at least one fold line. The at least one wall and fold line are arranged such that when the second portion is assembled and/or erected in use it defines a tray or container portion joined to the first portion.
