Description
If you’re running a 520 chain on dirt or adventure terrain, sprocket wear directly impacts your power delivery and chain life. The Renthal Twinring 51T combines a lightweight aluminum core with a steel outer ring, delivering the durability of all-steel designs while cutting rotational mass—giving you sharper throttle response and longer intervals between replacements. The self-cleaning mud grooves and permanent interference-fit construction mean less maintenance and more time riding hard.
