Renthal Twinring Rear Sprocket 52T Orange 2240-520-52GPOR

If you're running a 520 chain setup and want a sprocket that won't fail mid-race, the Renthal Twinring 52T delivers the durability you need without the weight penalty. By combining a lightweight 7075 T-6 aluminum core with an electro-less nickel-coated steel outer ring, this sprocket outlasts standard aluminum options by 3x while staying significantly lighter than all-steel alternatives. The self-cleaning mud grooves and reinforced socket head screws mean less maintenance and more consistent performance when conditions get gnarly.
