Description
24-tooth bicycle sprocket. Inner mounting hole diameter: 36.5 mm, outer diameter: 100 mm. Also used in the chain drive of walk-behind tractor seeders, planters, and diggers, or to increase traction power instead of the standard 19-tooth sprocket on "Ukraina" bicycles.
24-tooth (24T) Rear Bicycle Sprocket for Snap Ring — Concave (Dish)
The 24-tooth (24T) rear drive sprocket is designed for installation on coaster brake rear hubs (such as KT, Velosteel, KhVZ), as well as planetary hubs (Shimano Nexus, SRAM, Sturmey Archer) with a snap ring mounting interface (3-spline). The sprocket features a concave (dished/offset) shape, allowing for easy chainline adjustment by flipping it during installation.
Key Advantages and Features:
- Traction Gear Ratio (24T): The 24-tooth sprocket provides easier hill climbing and a smoother start, making it ideal for road, city, and cargo bikes.
- 3-Spline Interface: A standard, proven method of securing to the hub driver using a snap ring.
- Offset (Concave) Design: The dished profile allows the chainline to be shifted inward or outward by 3–5 mm simply by flipping the sprocket during installation.
- Durable Hardened Steel: Wear-resistant metal with a black protective coating, resistant to tooth deformation under high loads.
- Weight-Reduction Cutouts: 5 oval cutouts in the sprocket body reduce the overall weight of the part without sacrificing strength.
