Modern variations in bicycle design require several different chain lengths.
Fitting a standard-length replacement chain isn’t always an ideal option.
M-Wave have made a great solution for professional workshops who need access to specialist chain lengths. Great when a cargo-bike or ‘random Tandem’ turns up looking for a new chain. 
These 15M Mini rolls of KMC made chain (approximately 10 chains) come in a small box on a cardboard reel that can sit on most shelves and allow the mechanic to pull-out and custom cut a chain to the exact length required.
Supplied with 10 joining links.
