Master Link: Some Highlights

Author: AngieKTurner | Posted: 08.06.2012

A masterlink, also known as quick release link, is a bicycle chain accessory, which allows convenient reconnection and removal of installed bicycle chains without the need for chain tools. These links act like a set of the chain’s outer plating, so joining a pair of the chain’s inner plate ends. These tools are needed to get the chain’s length adjusted. Adjustments are necessary while shortening a brand new chain for primary fitting.

Masterlink is available in two major styles. In both the cases, the link set consists essentially of two outer plates. Now, each one of these, in turn, resembles the chain’s outer plate. Keeping such considerations in mind, let us now throw some light on the oldest masterlink variety available today- the straight chain line compatible.

These links have been around for quiet some time now, serving generations of bicycle owners. It essentially features two pins, which again are connected to the same plate. It is used in a plethora of bicycle systems like the hub geared, single speed or drive train systems. In the drive train system, especially, the outer plates featuring the two pins are spaced at more or less the same pitch as the chain itself. The pin’s free ends are grooved to have the right effect. Both the pins form an extremely loose fit in the inner plate’s bushings. The pins, therefore, slide through the rollers of the chain.

This connecting chain link comes with different kinds of side plates. In some, the side plates are simply raised to the top. In others, the side links are straight. Since chains on derailleur-fitted bikes or bicycles are reversed for a portion of their excursion through drive trains and because certain cogsets feature close ramp tolerances, these links might cause serious malfunctions if an inappropriate selection is made. Bushingless chains, on the other hand, feature smaller projections and are used primarily on bicycles having large cogsets. This is because their tolerances are known to be more critical or delicate than those having seven speeds only.
