Description
If you’re running a 520 chain and demand sprocket durability that won’t compromise your bike’s weight, the Renthal TwinRing rear sprocket delivers the performance advantage you need. The dual-ring construction—pairing a lightweight 7075 T-6 aluminum inner ring with an electro-less nickel-coated steel outer ring—outlasts conventional all-aluminum sprockets by three times while staying significantly lighter than all-steel alternatives. Self-cleaning mud grooves and permanent thermal bonding mean you get extended service life and reduced maintenance, giving you more time riding and less time worrying about wear.
