The photograph is indicative. RYNO sprockets from Thailand are made using specialist techniques and advanced laser machinery, then put through very strict quality control. Their material is made so that the sprockets give maximum performance at the lowest possible cost. Every RYNO sprocket goes through a special heat treatment that increases its strength and its life, which the manufacturer puts at 20,000 km. Every laser-cut sprocket has a different pattern for each part number, so it stands out and smartens up your bike.
