Buyer’s Guide

How to choose the best Bike Sprocket

The purpose of a bike sprocket is to allow the chain to travel around the sprocket teeth. Without a sprocket the chain would be free to slide along the frame of the bike. This could cause problems because the chain could slip off the rear wheel causing the rider to fall. Also the chain could become damaged due to rubbing against the frame. With a sprocket the chain travels around the sprocket teeth which prevents these issues from occurring.

There are two types of chains; single-speed and double-speed. Single speed chains only go around one sprocket while double-speed chains go around both sides of the sprocket. Double-speed chains are stronger than single-speed chains because there are twice as many links per inch. However single-speed chains are easier to maintain because they require fewer parts.

Types Of Bicycles

Bicycle frames vary depending on the type of riding style. There are road bicycles mountain bikes BMX bikes cruiser bikes and track bikes. Road bicycles are designed for long distance rides and are typically built using steel tubing. Mountain bikes are designed for rugged terrain and are typically built using aluminum tubes. BMX bikes are designed for short distances and are typically built using plastic tubing. Cruiser bikes are designed for city streets and are typically built using steel tubing. Track bikes are designed for racing and are typically built using carbon fiber.

Sprocket Types

There are three different types of sprockets; fixed gear freewheel and hub gears. Fixed gear sprockets are attached directly to the axle of the rear wheel. Freewheel sprockets spin freely and are connected to the crank arm via a ratchet mechanism. Hub gears are mounted inside the front fork and connect to the pedals.

Chain Type

Single-speed chains are either straight or V-shaped. Straight chains are commonly found on single-speed bikes. V-shaped chains are common on double-speed bikes.

Bike sprockets are important parts of bicycles. Without these components there wouldn’t be any way to get the wheels turning. There are many different types of sprockets available today each designed to perform specific functions. Some sprockets are meant to provide power while others are designed to increase speed. In order to determine which type of sprocket best suits your needs you must understand exactly what function you require.

Types of Bicycle Sprockets

There are two main categories of bicycle sprockets; fixed gear and freewheel. Fixed gear sprockets are attached directly to the rear wheel axle. Freewheel sprockets allow the rider to spin freely around the axis of the hub. Both types of sprockets are commonly found on mountain bikes road bikes BMX bikes and children’s bikes. However there are several differences between the two types of sprockets. For example fixed gear sprockets are generally stronger than freewheel sprockets because they cannot rotate within the frame. Additionally fixed gear sprockets are typically heavier than freewheel sprockets due to the fact that they are permanently affixed to the axle. Finally fixed gear sprockets are easier to maintain since they do not require lubrication.


Both fixed gear and free-wheel sprockets are very useful tools. However there are certain situations where only one type of sprocket will suit your needs. For instance if you ride primarily on flat ground a fixed gear sprocket will likely suffice. Conversely if you frequently climb hills a freewheel sprocket will prove beneficial. Regardless of whether you ride a fixed gear or freewheel bike always ensure that you select a high quality sprocket. Poor quality sprockets can cause serious problems including damaged spokes and broken chain links.

How To Choose A High Quality Bicycle Sprocket

In order to choose the right sprocket for your bike you must first identify its intended usage.

Bike sprockets are important parts of bicycles. The sprocket is responsible for turning the chain around the rear wheel. There are many different types of sprockets available today. Each type has its own advantages and disadvantages. Here are some features to look for when choosing a sprocket.

Chainring Size – Chainrings are measured in teeth per inch (TPI). Most modern road bikes use 11-28 TPI chains. Some mountain bikes use 10-25 TPI chains. Road racing bikes typically use 12-24 TPI chains. Mountain biking uses smaller chains because there is less weight being carried.

Number of Gears – Bicycles generally have three gears. However some have four or five. The number of gears determines how fast the rider can go. More gears allow the cyclist to climb hills faster.

Material – Bicycle sprockets are made of steel aluminum titanium carbon fiber ceramic or plastic. Steel is the most common material. Aluminum is lighter than steel and is commonly found on mountain bikes. Titanium is stronger than steel and is commonly found on high end road bikes. Carbon Fiber is strong and light. Ceramic is very hard and durable. Plastic is cheap and easy to mold into complex shapes.

Shape – Shapes include round oval square hexagonal octagonal and triangular. Round is the most popular shape. Oval is slightly wider than round. Square is widest at the top and narrowest at the bottom. Hexagonals are shaped like six sided dice. Octagons are eight sides. Triangles are wide at the base and taper towards the tip.

Finish – Finishes vary depending on the manufacturer. Polished finishes are shiny and reflective. Black oxide finish is matte black. Chrome plating is chrome colored. Anodizing is a process where metal is electroplated with another metal. The result is a color change.

Size – Sizes range from 1/8″ to 3″. Smaller sprockets fit small sized wheels. Larger sprockets fit large sized wheels.

Different Types Of Bicycle Chain

Bicycle chains are very important parts of bicycles. The most common type of bicycle chain is called “freewheel”. Freewheels are designed to be able to rotate freely while being connected to the rear wheel hub. There are two main types of freewheels; fixed-gear and freehub. Fixed gear freewheels are attached directly to the pedals and cannot spin freely. Freehub freewheels allow the rider to change gears by turning the pedal backwards and forwards. Most modern bicycles use freehub freewheels because they are easier to maintain and repair.

Types Of Chains

There are many different kinds of bicycle chains available today. Some of these include single speed double speed triple speed and five speeds. Single speed refers to a bike where only one gear is provided. Double speed refers to a bike with two gears. Triple speed refers to three gears. Five speed refers to four gears plus a fifth gear which is sometimes referred to as “coaster” or “cruise.” All of these refer to the number of teeth per inch (TPI) on the chainring. For example a 10T chain has ten teeth per inch.

Chain Tensioners

The tensioner is a small spring loaded mechanism that holds the chain tight around the chainrings. Without a tensioner the chain could slip off the ring causing serious injury. In addition the chain could wear unevenly and cause premature failure.

How To Check Chain Tension

To check the chain tension pull back on the handlebars and watch the chain. If the chain moves too far forward there is no tension. If the chain does not move at all the chain is too loose.

Chain Lube

Lubrication is essential to maintaining good performance and preventing problems. Many cyclists apply grease to the inside of the chain rings. Others lubricate the outside of the chain using oil. Oil works best if applied regularly. However grease is effective immediately and lasts longer.
