Replacement Pads for Hayden M6 Primary Chain Tensioners

This is the right stuff for everybody looking for smooth power transfer instead of noisy “clunk” shifting. Unlike the original setup, the M6 features a spring beneath the adjuster shoe which exerts proper pressure to the chain. With the original chain tensioner the chain - even when adjusted correctly - still has approx. 10 mm slack and exactly this leads to vibrations and hard shifting.
