Key Features
- Higher Gear Ratio: The 15-tooth design provides more speed per RPM compared to standard 10T or 12T sprockets, making it the go-to choice for open-trail riding and higher top speeds.
- Stainless Steel Manufacturing: Unlike standard carbon steel sprockets, this stainless steel version offers exceptional resistance to rust and oxidation, ensuring the teeth stay sharp even in wet or muddy environments.
- Optimized Thermal Endurance: Engineered with high heat resistance to prevent the sprocket from softening during long, high-RPM rides, maintaining precise chain engagement at all times.
- Universal 35mm Mounting: Features a 35mm bolt-hole spacing designed to fit the standard 20mm shaft locking plates used by major Chinese pit bike manufacturers.
- Precision Mechanical Timing: Designed to mesh perfectly with any 420-pitch chain, reducing mechanical drag and ensuring efficient power transfer from the crankshaft to the rear wheel.
