Used Full E Charged chain tensioner blocks/ axle blocks in black for Surron X. As shown in pictures they show signs of wear but have absolutely no issues performance wise and have plenty of life in them. I have changed to a different colour hence why I am selling. Thanks for checking out my listing :). Product Description: Upgrade your axle block chain adjuster to keep your chain at the optimal alignment whilst also adding a bit of style to your ride. With these adjusters, a quick turn of the adjustment screw lets you easily and precisely adjust your chain tension.
