Fixed screwed sprocket 18 teeth

Why choose an 18 tooth fixed gear sprocket for your fixie ?

The fixie world—minimalist, sleek, and full of character—continues to attract urban cyclists who value simplicity and control. At the heart of this stripped-back setup lies the transmission, where every component plays a key role. One essential piece ? The 18 tooth fixed gear sprocket. This small but mighty part strikes the perfect balance between responsiveness and ride comfort. Let’s take a closer look at why it deserves a spot on your rear wheel.

The fixed sprocket: core of the fixie transmission

On a fixed gear bike, there’s a direct connection between your crankset and the rear wheel. No freewheel, no coasting—if your legs move, the bike moves. If you stop pedaling, so does the wheel. This creates a unique riding experience where control and cadence are everything.

The 18 tooth sprocket is central to this setup. It defines the gear ratio, impacting how far you go with each pedal stroke and how your bike responds in traffic, on hills, or during skids.

Why go with an 18 tooth fixed gear sprocket ?

The 18t sprocket is a popular choice among urban riders and fixie purists for its well-balanced gearing. It’s not too light, not too heavy—just right for everyday riding.

Key benefits of the 18t sprocket :

• Versatility: Pair it with a 46-tooth chainring and you get a 2.55 ratio (46/18)—perfect for city riding, rolling terrain, and quick accelerations.

• Smooth Pedal Stroke: Provides fluid cadence without sacrificing speed, even on slight inclines.

• Precision Control: Ideal for skidding and responsive braking—especially when riding brakeless.

Technical specs

A quality 18 tooth fixed gear sprocket usually features:

• BSA thread (1.37" x 24 TPI) for compatibility with most standard threaded fixie hubs.

• High-strength steel construction, often chromoly or heat-treated for better durability under chain tension.
