Chain tensioner

thingiverse

A compact, adaptable accessory has been cleverly crafted by cyclists to improve chain retention and riding smoothness on Gazelle bicycles - this component goes under the name of chain tensioner. Its functionality stems from using an adjustable spring or screw to carefully monitor and adjust tension as needed to compensate for various conditions during cycling like dirt buildup and slight movement along chain stays due to uneven surfaces traveled. It generally requires users with intermediate level experience handling DIY tools but offers reliable outcomes upon successful installation according to Gazelle manuals which are designed keeping specific needs in mind that differ from brand model variations so please always refer first.
