With a modern Oring chain (RK Xring) there is no necessity to have that cesspool of oil and grime. Wash the chain and sprocket when washing the bike, spray some compatible chain lube on a clean rag and run the chain through the rag, no more cesspool, and a much longer life chain, and a quieter chain too. No more cesspool, and hardly no adjustments to be made. No more cesspool.
