§ 02 / About this part
What it is
The RENTHAL SPROCKET R 520 50T BK SC TWIN, sprockets. Stocked by Iron Offroad, the UK MX hard parts specialist.
This rear drive component uses a dual-material design. The outer steel ring handles the chain torque and resists tooth wear. The inner aluminium section reduces unsprung weight at the hub. Replace this when teeth begin to hook or show visible thinning. Always fit a new chain and front sprocket at the same time to prevent premature wear on the new teeth. Check your chain tension after the first heat cycle. This part is built for high-hour enduro use and gritty MX conditions where standard aluminium rings wear too quickly.
