RENTHAL 112U-520 Ultralight Grooved Rear Sprocket

Renthal Ultralight™ rear chainwheels are manufactured to extremely tight tolerances from 7075 T6 aluminium alloy which is 66% lighter than steel, yet incredibly durable. Their advanced tooth profile, concentricity and accuracy of fit provide maximum power transfer and long-life. Renthal´s combination of a high strength base material and exceptionally hardwearing surface result in significantly increased chainwheel life over other brands. Weight: - 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. Material: - High strength specially enhanced 7075 T6 aluminium alloy is used to create the perfect rear chainwheel, that is both lightweight, durable and strong. Mud Grooves: - Ultralight™ Rear Chainwheels feature Renthal´s self-cleaning mud groove technology between each tooth. This prevents mud build up that traditionally leads to quicker wearing components. Colours: - Ultralight Rear Chainwheels are available in 6 colours to help you personalise your setup. The available colours are Black, Blue, Red, Green, Orange and Silver. The anodised surface finish provides an integral coating preventing corrosion. A 15-step process is carefully carried on on each chainwheel individually. Specifications: - Chain Pitch: 520 - Net Weight: 0.42 Kg - Teeth: 50
