Freewheel screwed 7 speed

7-Speed freewheel 14-28: a classic bicycle drivetrain component

The 7-speed freewheel 14-28 is a key component in the world of cycling, especially for entry-level and mid-range bikes, including city bikes, hybrid bikes, and leisure mountain bikes. Easy to install, affordable, and reliable, it remains a popular solution for screw-on drivetrains. But what exactly are its features? Who is it for? And how do you choose the right one?

What is a screw-On freewheel ?

A freewheel is a drivetrain component that holds the rear cogs of a bike. Unlike modern cassettes that mount onto a freehub body, a freewheel screws directly onto the rear wheel hub. It contains an internal ratcheting mechanism that allows the rider to pedal forward and coast freely.

A 7-speed 14-28 model means it includes 7 cogs, ranging from a small 14-tooth cog (for faster speeds on flat terrain) to a large 28-tooth cog (for easier climbing).

Key features of the 7-speed freewheel 14-28

• Number of gears: 7 cogs

• Gear range: 14 / 16 / 18 / 20 / 22 / 24 / 28 teeth (may vary by brand)

• Mount type: Screw-on (standard BSA threading: 1.37" x 24 tpi)

• Compatibility: 7-speed drivetrains with rear derailleurs and shifters (indexed or friction)

• Chain compatibility: 6/7/8-speed chains (width 7.1 to 7.3 mm)

• Typical use: City bikes, hybrid bikes, leisure MTBs, vintage or older bicycles

This 14-28 setup is ideal for versatile riding: it offers enough gear range to handle climbs with ease while allowing for smooth cruising on flat roads.

Benefits of a 14-28 screw-on freewheel

• Simple installation – no need for a freehub body, just screw it onto the threaded hub

• Budget-friendly – one of the most cost-effective drivetrain solutions

• Versatile – suitable for urban commuting, leisure rides, and recreational cycling

• Widely available – easy to find both new and used, and compatible with many older setups

Who is it for ?

The 7-speed freewheel 14-28 is ideal for casual cyclists, touring enthusiasts, or those looking to restore an old bicycle or maintain a reliable hybrid. It’s also common on entry-level bikes, kids' bikes, folding bikes, and rental fleets.

It’s a great option for anyone seeking a simple, durable drivetrain that’s easy to maintain and doesn’t require complex upgrades.

Compatibility and maintenance tips

Before replacing an old freewheel, check the following:

• Your rear hub is threaded, not a modern freehub body

• Your rear derailleur can handle a 28-tooth large cog (check total capacity)

• Your chain is in good condition, as worn chains can skip on new cogs

Regular cleaning and lubrication of your drivetrain—chain, derailleur, and freewheel—will extend its lifespan and maintain smooth performance.

Conclusion

Simple, versatile, and affordable, the 7-speed freewheel 14-28 is a tried-and-true option for a wide range of bicycles. It provides a balanced gear range, is easy to install, and keeps maintenance to a minimum. A solid choice for riders who value efficiency without complexity.
