Sport Bicycle Freewheel (7-Speed)

7-Speed Bicycle Freewheel (14–28T, Threaded Mount)

7-speed threaded freewheel block is designed for installation on the rear hub of mountain (MTB), city, road, and hybrid bicycles. The design includes 7 driven sprockets and an integrated ratchet freewheel mechanism. The part screws onto the rear hub via standard threads and provides crisp and precise gear shifting in 7-speed and 21-speed (3x7) drivetrains.

Key Advantages and Features:

• Popular Gear Range (14–28T): The optimal tooth count allows for easy selection of the required cadence for both uphill climbs and high-speed riding on flat surfaces.
• Standard Threaded Mount: Screws onto most threaded hubs in the budget and mid-range segments (Shimano, SunRun, Shunfeng, Quanindo, etc.).
• Durable Hardened Steel: The wear-resistant alloy with a protective anti-corrosion coating guarantees the longevity of the sprockets under chain load.
• Simple Replacement: Quick installation using a standard bicycle freewheel removal tool.

Compatibility with Bicycles and Chains:

• Bicycle Types: Mountain (MTB), cross, city, road, and folding bikes with a 7-speed drivetrain (or 21-speed with a 3-speed front system).
• Compatible Chains: Standard 6–7–8 speed bicycle chains (1/2" x 3/32").

Maintenance Tip: When replacing a 7-speed freewheel, it is recommended to check the condition of the chain. If the old chain is significantly stretched, it may skip on the new sprockets, so they are often replaced as a pair.
