EBike 13Tooth Chain Sprocket (Steel + Rubber) Key benefits Optimized 13tooth profile designed to improve drivetrain performance on soft tail frame bicycles, helping deliver more consistent engagement and smoother pedaling. Durable steelandrubber construction resists wear and compression during use so the sprocket maintains shape and function over time. Lightweight at approximately 90 g to preserve bike agility and minimize added mass while still providing stable support for the chain. Precise inner diameter of about 9 mm for broad compatibility with many ebike shafts and hubs, making installation straightforward on compatible models. What this sprocket solves Replaces worn or damaged sprockets with a component that balances durability and weight to restore reliable chain engagement. Reduces the risk of premature deformation under load thanks to its compressionresistant construction, extending service life between replacements. Keeps handling responsive on soft tail frames by avoiding unnecessary weight while still providing needed strength. Specifications Teeth: 13 (smart design tailored for soft tail frames) Materials: steel core with rubber elements for compression resistance Weight: approximately 90 g Inner diameter: approximately 9 mm Practical applications Daily commuting: swap in this sprocket to a worn part and maintain smooth, reliable pedaling for city or suburban rides. Weekend trail rides: use on soft tail ebikes to preserve responsive handling while benefiting from a durable, compressionresistant component. Maintenance or light upgrades: ideal for routine drivetrain maintenance or when upgrading to a lighter yet robust sprocket without changing the bike's drivetrain geometry. Compatibility and installation notes Inner diameter of about 9 mm fits a wide range of ebike shafts and hubs; confirm your bike's shaft size before to ensure compatibility. Designed specifically with soft tail frame bicycles in mind; check fitment against your model's specifications. Why choose this sprocket Purposebuilt tooth count and profile for improved engagement on soft tail frames. Balanced steelandrubber build delivers durability without unnecessary weight. Clear sizing and straightforward compatibility to make replacement and upkeep simple and reliable.
