Product: RK steel rear sprocket, 45 teeth, 525 pitch, part number 32-35F-45 (steel construction)
Purpose / Use: Fits riders who want a durable, low-cost replacement rear sprocket, suitable for general street/track use where strength and wear resistance are prioritized over weight savings
Material: Steel (carbon/alloy steel)—not lightweight but durable
Pitch: 525 (standard size for many bikes)
Performance Considerations:
• More wear-resistant than aluminum sprockets; less prone to rounding or failure under load
• Slightly more mass (and thus rotational inertia) compared to lighter materials
• Good option where strength and longevity are more important than weight
