Shimano Tourney MF-TZ20 / MF-TZ500-6 Bicycle Freewheel (6-speed, 14ā28T, threaded)
The original Shimano Tourney MF-TZ20 6-speed bicycle freewheel is designed for installation on the rear hub of mountain (MTB), city, folding, road, and youth bikes. The part screws onto the hub using standard threads and combines a block of 6 driven sprockets with an internal ratcheting freewheel mechanism. Shimano's proprietary technology ensures crisp, quiet, and smooth gear shifting.
Key Benefits and Features:
- 100% Genuine Shimano: Precise tooth geometry and high reliability of the internal ratchet mechanism.
- Smooth Shifting Technology: Specially profiled teeth and chamfers facilitate chain transition from one sprocket to another under load.
- Classic Gear Range (14ā28T): Optimal gear selection for comfortable climbing and confident acceleration on flat roads.
- Protective Anti-Corrosion Coating: A combined finish (black large sprocket + bronze main sprockets) protects the part from wear and rust.
Compatibility with Bicycles and Drivetrains:
- Bicycle Types: Mountain, city, road, folding, and youth bikes with a 6-speed (or 18-speed 3x6) drivetrain.
- Hub Type: Rear hub with classic right-hand threading.
- Compatible Chains: Standard 6/7/8-speed bicycle chains (Shimano HG40, KMC Z6/Z7).
