At DMG Motorsports, we present the SUPERSPROX Edge Rear Sprocket, a lightweight 45-tooth steel sprocket designed for 525 chain applications. Its CNC-machined construction delivers a precise fit, while the durable black Tri-Zink finish helps resist corrosion. The Edge design offers a modern upgrade over traditional stamped steel sprockets and may reduce weight by 5%–15%, depending on the model.

Features:

• CNC-machined steel construction for long life and superior fit
• 45-tooth rear sprocket for 525 chain
• Durable black Tri-Zink finish for corrosion resistance
• Lighter than traditional steel sprockets; weight reduction varies by model
• Edge aluminum insert discs fit into the sprocket inset
