Hycline 7-Speed Freewheel 14-28T — Threaded Rear Hub Fit, High-Tensile Steel, Smooth Shifting

The Hycline Bike Freewheel 7 Speed 14-28T is a threaded, high‑tensile steel cassette-style freewheel built to deliver smooth, reliable 7-speed shifting for a wide range of bikes.

This freewheel fits standard threaded rear hubs and provides a familiar 14-16-18-20-22-24-28T gear progression in a compact, robust package. Made from high‑tensile steel, it balances strength and longevity while the precision internal thread ensures an accurate fit on compatible hubs. It ships lightly lubricated for immediate installation and is engineered for controlled chain engagement during shifts without exotic materials or unnecessary weight.

How does this freewheel improve shifting on my bike?

The Hycline 7-speed uses a uniquely profiled sprocket and shift ramps to guide the chain cleanly between cogs, reducing missed shifts and chain hang-ups. Its tooth geometry is designed to work with common 7-speed drivetrains like Shimano and Sram systems for consistent performance.

• Specialized shift ramps and tooth profile for precise chain control
• Compatible with Shimano and Sram indexed shifting
• Even 14–28T progression for predictable cadence changes
• High‑tensile steel cogs for durability under load

How easy is it to install and maintain?

Installation is straightforward on any bike with a standard threaded rear hub; the precision internal thread helps the freewheel seat correctly and rotate smoothly. The unit arrives with lubrication applied, and routine maintenance is limited to periodic cleaning and re‑lubrication depending on riding conditions.

• Threaded design fits standard rear hubs without adapters
• Pre‑lubricated for immediate use out of the box
• Low‑noise rotation thanks to high‑precision threading
• Simple maintenance: clean and add chain/freewheel oil as needed

Which bikes and drivetrains are compatible with this Hycline freewheel?

This freewheel was designed for broad compatibility with many bicycle types that accept threaded freewheels, such as older MTBs, cruisers, BMX, fat bikes, hybrids and some e‑bikes. It pairs with most standard 7‑speed derailleur systems, including those from Shimano and Sram, though cassette hubs and multi‑speed freehubs use different standards.

• Works with threaded rear hubs (classic freewheel standard)
• Compatible with Shimano and Sram 7‑speed drivetrain components
• Suitable for MTB, BMX, hybrid, cruiser, fat bike and many e‑bikes
• Not for use with cassette/freehub systems that require splined cassettes

What are the physical specs and construction details?

The Hycline 7‑speed freewheel weighs about 427 g (15.1 oz) and contains seven steel cogs in a 14–28T range. High‑tensile steel provides strength for demanding rides, and the compact stack fits most older hub threads while keeping overall weight reasonable.

Who is this for: The Hycline Bike Freewheel 7 Speed 14-28T is aimed at riders who need a dependable, serviceable 7‑speed freewheel for threaded hubs — whether restoring a classic bike, upgrading a commuter or fitting a replacement on a trail bike. Choose this product if you want a robust steel construction, predictable gear steps, and broad compatibility with Shimano and Sram 7‑speed drivetrains. If you require a splined cassette for a modern freehub, check your hub type before purchasing. Images are illustrative; minor factory lubrication marks are normal and not damage.
