Description
If you’re running a 520 chain setup and want a rear sprocket that actually lasts, the Renthal TwinRing 48T delivers. This isn’t just another aluminum sprocket—the hybrid construction pairs a lightweight 7075 T-6 aluminum core with an electro-less nickel-coated steel ring, giving you three times the lifespan of all-aluminum alternatives without the weight penalty of solid steel. The self-cleaning mud grooves and reinforced socket head screws mean less maintenance and better durability when you’re pushing hard in demanding conditions.
