Description
If you’re running a 520 chain on your race bike, transmission efficiency directly impacts your power delivery and lap times. The ThreeD 520 Z uses precision forging and strategic lightening holes to deliver a stiffer, more responsive chain that accelerates harder while shedding unnecessary weight. This isn’t just a chain—it’s a measurable upgrade to your drivetrain’s performance and longevity.
The special pin design with dual holes allows ThreeD to remove material without sacrificing strength, while edge-cut inner plates reduce friction during sprocket engagement. You’ll notice smoother power transfer, better heat dissipation, and less mud accumulation during trail or track use.
