Sprocket - Drive - Front - 520 - JTF577 Series - 15 Tooth - Rubber Cushion - XT550 - XT600

JT Sprockets are computer designed to achieve ultimate strength while retaining as little weight as possible. Made from chromoly steel alloy they meet or exceed all possible industry standards and have indeed become an industry standard in themselves. This RB series sprocket is also rubber cushioned to dampen chain impact allowing for a reduction in drivetrain noise / vibration / harshness. Remember to always replace sprockets and chain as a set. Running a new sprocket or chain in an otherwise worn out system will only cause premature wear and further expense and headache.
