Ergal Ultralight Rear Sprocket (525-42t) | Hard Ansed Renthal

Renthal® Ultralight™ Hard Anodised Rear Chainwheels are specifically designed for Street and road racing applications. CNC machined from the same 7075 T6 material as Renthal's offroad chainwheels, with increased longevity from the hard anodising finish. Hard anodizing is an integral surface coating which significantly increases the surface hardness and wear resistance of the rear sprocket. They are available in a variety of tooth sizes. ULTRALIGHT Designed to keep revolving un-sprung mass to an absolute minimum and power transfer at a maximum, Renthal Ultralight™ rear chainwheels are 66% lighter than steel. CNC MACHINED Each Ultralight™ Rear Chainwheel that leaves Renthal's engineering facilities in the UK is individually CNC machined to the tightest possible tolerances, ensuring an accurate and reliable fit. HIGH-QUALITY MATERIAL High strength specially enhanced 7075 T6 aluminum alloy is used to create the perfect rear chainwheel, that is both lightweight, durable, and strong. HARD ANODISING To help improve overall wear resistance of Renthal Road Chainwheels a hard anodizing coating is applied which increases the hardness of the material giving better wear resistance. FACTORY FIT As used by the Kawasaki World Superbike team. 2013, 2015, 2016, 2017 and 2018 World Superbike championship winning chainwheels.
