A chain tool includes a body having a driving hole, a stop portion, and a receiving portion located between the driving hole and the stop portion in an axial direction. A pressing member is received in the receiving portion and is movable relative to the body in the axial direction. A push member is in threading connection with the first threaded portion and is movable relative to the body between a first position distant to the stop portion and a second position adjacent to the stop portion. The pressing member is pressed by the push member and moves in an arcuate path when the push member moves between the first and second positions.

A track chain member comprising a shoe member defining a track chain traveling direction and a lateral direction, the shoe member further defining a first lateral end, a second lateral end, and a ground engaging surface spanning from the one end to the other end; wherein the shoe member further defines a first side void proximate the first lateral end, a second side void proximate the second lateral end, and the first side void terminates a first predetermined distance from the first lateral end and the second side void terminates a second predetermined distance from the second lateral end.

A chain master link tool includes a first lever and a second lever pivotally and releasably coupled together. Each of the first and second levers include a first working portions and a second working portion. The first and second levers are pivotal to an extended position in which the first working portions face oppositely and are disposed apart and cooperatively delimit a connection space therebetween for connection of a master link with a roller chain assembly and the second working portions face oppositely and are disposed apart and cooperatively delimit a removal space therebetween for removal of the master link from the roller chain assembly respectively.

A method and tool provide for removal of a rear bicycle wheel of a bicycle having a wheel with an axle mounted cassette of cogs. The tool includes a chain disengagement element movable with respect to an axle mounted cassette, wherein moving the chain disengagement element moves a portion of the chain away from the axle mounted cassette sufficiently to completely disengage the chain from the axle mounted cassette. This allows for easy removal of the wheel.
