§ 02 / About this part
What it is
The RENTHAL SPROCK R 520 40T SI UL SC, sprockets. Stocked by Iron Offroad, the UK MX hard parts specialist.
This rear sprocket reduces unsprung weight to improve suspension tracking and acceleration. It is machined from high-strength aluminium for a balance of durability and lightness. Changing your tooth count allows you to tune your bike for tighter technical tracks or faster open sections. Always install a new chain when replacing sprockets to prevent premature wear on the new teeth. It mounts directly to your rear hub using standard sprocket bolts. This component is a critical wear item for any MX or enduro bike.
