Bicycle Chain Sprocket (19T, 3 Splines)

19-tooth driven bicycle chain sprocket. Inner hole diameter: 36 mm, outer diameter: 82 mm

Rear Bicycle Sprocket 19T (teeth) — 36 mm fit (three-spline, keyed)

The 19-tooth (19T) rear driven sprocket is designed for installation on the rear hub of road, city, folding, and single-speed bicycles, as well as models with coaster brake hubs (such as "Ukraina", Torpedo, HVZ) and internal gear hubs. The sprocket is secured to the driver/hub using 3 internal slots (splines) and a snap ring, ensuring reliable torque transmission from the chain to the wheel.

Key Advantages and Features:

• Optimal Gear Ratio (19T): Provides a balance between an easy start, comfortable hill climbing, and good rolling performance on flat roads.
• Reliable Three-Spline Mount: The 36 mm mounting diameter with 3 slots prevents the sprocket from slipping on the hub even under high loads.
• Durable Hardened Steel: The wear-resistant metal alloy is resistant to tooth abrasion and the impact of wide single-speed chains (1/2" x 1/8").
• Classic Dished Profile: Allows for chainline adjustment by installing the sprocket with the dish facing inward or outward.

Compatibility with Hubs and Bicycles:

• Coaster Brake Hubs (Single Speed / Torpedo): "Ukraina", "Aist", "Minsk", "Desna", "Salyut", HVZ, PVZ, Velosteel, and their modern equivalents.
• Internal Gear Hubs: Shimano Nexus (3, 7, 8 speeds), SRAM, Sturmey Archer (for three-spline fit).

Sprocket selection tip: The more teeth on the rear sprocket (e.g., 19T or 21T instead of 16T), the easier it is to pedal when starting and going uphill, but the maximum speed at the same cadence will be slightly lower.
