Fixed gear lockring: the essential part for a reliable fixie transmission
In the world of fixed gear bikes, every component of the drivetrain plays a critical role. While the fixed cog is the heart of the setup, it can't function properly without one often overlooked but essential part: the lockring.
What is a fixed gear lockring ?
The lockring is a small threaded ring that screws onto the rear hub, right after the fixed cog. Its job is simple but crucial: to lock the cog in place and prevent it from unscrewing when backpedaling — a common motion when braking on a fixie.
Why is it so important on a fixed gear bike ?
Unlike traditional bike drivetrains, a fixie has no freewheel and no derailleur. The rider is in constant engagement with the rear wheel: when the wheel spins, the crankset spins too. During a leg-powered brake, strong reverse torque is applied to the cog. Without a lockring, the cog can start unscrewing — which could lead to a dangerous drivetrain failure.
That’s where the lockring comes in: it’s a mechanical safeguard that maintains proper tension and alignment of the cog on the hub.
Key features of a good fixed gear lockring
-
BSA threading (1.29" x 24 tpi): the most common standard, compatible with most threaded fixie hubs.
-
Hardened steel or anodized aluminum: steel offers maximum strength, while aluminum brings lightness and style.
-
Notches for specific tools: a good lockring has slots or teeth that work with a lockring wrench for secure tightening.
-
Slim profile: fits snugly after the cog without interfering with the chainline.
-
🔒 Reverse threading: some models use left-hand threads to better resist loosening under torque.
How to install it properly
-
Thread the fixed cog onto the hub by hand.
-
Use a cog wrench to tighten it securely.
-
Then thread the lockring against the cog.
-
Use a lockring tool to firmly tighten it.
-
Spin the cranks backward to check that everything is snug and secure.
Tips from one fixie rider to another
-
Check the lockring tension regularly, especially if you ride brakeless or in busy urban traffic.
-
If you hear any clicking or feel drivetrain play, inspect the cog and lockring first.
-
Want to personalize your ride? Lockrings are available in custom colors to match your single-speed drivetrain.
To sum it up, the fixed gear lockring may be small, but it plays a huge role in the safety and performance of your fixie. Whether you're a hardcore fixed gear enthusiast or just looking for a solid urban setup, this little piece of your transmission is not one to overlook.
