About This Product
Chain elongation causes a decrease in transmission efficiency. It also accelerates chain and sprocket wear and shortens their lifespan. KANA Tightmaster is an automatic tension type with a built-in spring and comes with a standard idler.
*The black-dyed surface treatment of the included idler sprocket will be discontinued with the current stock. Due to replacement, products before specification changes may be mixed in. It is not possible to specify with or without black dyeing. Thank you for your understanding.
