Understanding Bike Brake Cables
What Are Bike Brake Cables?
Bike brake cables are responsible for transmitting force from the brake levers to the brake calipers, resulting in the wheels slowing down and eventually stopping. They are made up of a steel inner cable and an outer housing.
How Do They Work To Stop The Bike?
When you squeeze the brake lever, the cable moves through the outer housing and eventually pulls the brake calipers towards the wheel rim. This creates friction, and the wheel slows down or comes to a complete stop, depending on how hard you apply the brakes.
The more force you use on the brake lever, the more the brake pads will clamp down on the rim, and the faster you will stop.
Different Types Of Bike Brake Cables — Caliper Brakes, Cantilever Brakes, And Disc Brakes
There are three main types of bike brakes: caliper brakes, cantilever brakes, and disc brakes. Each type of brake has a unique cable system.
Caliper Brakes
One of the most common types of bike brakes, caliper brakes are widely used on road bikes and some hybrid bikes. The brake cable attaches to a single bolt on the brake caliper, and when the lever is squeezed, the cable pulls the caliper arms together, forcing the brake pads to clamp down on the rim.
Cantilever Brakes
Cantilever brakes feature a more complicated cable system than caliper brakes. The brake cable attaches to a straddle cable, which creates a “v” shape and attaches to each of the brake arms. When the brake lever is squeezed, the brake cable tightens, pulling the straddle cable and the brake arms together, forcing the brake pads to clamp down on the rim.
Disc Brakes
Disc brakes use a completely different system than caliper or cantilever brakes. The brake cable attaches to a brake lever, just like other brakes, but instead of pulling a brake caliper, the cable pulls a small piston in the brake lever.
This piston pushes hydraulic fluid through a hose and into a brake caliper attached to the wheel hub. The caliper then squeezes the brake pads onto a rotor, stopping the wheel from spinning.
Pros And Cons Of Each Type Of Brake Cables
Each type of brake cable has its pros and cons, depending on the type of cycling you do.
Caliper Brakes
Pros:
- Lightweight
- Low profile
- Easy to maintain
Cons:
- Limited tire clearance
- Not as powerful as other brake systems
- Can wear out brake tracks on rims
Cantilever Brakes
Pros:
- Works with a wide range of tires and rim widths
- Offers more stopping power than caliper brakes
- Self-centering
Cons:
- Complicated design can make maintenance difficult
- Straddle cable can interfere with some bags and racks
- Requires more brake cable than other types of brakes
Disc Brakes
Pros:
- Offers the most powerful stopping ability of any brake system
- Consistent performance in all weather conditions
- Minimal rim wear
Cons:
- Heavy
- Can be more difficult to maintain
- Requires specific wheel and frame compatibility
By understanding the different types of bike brake cables and how they work, you can choose the best type of brake system for your riding needs and preferences.
Getting To Know Gear Cables
If you’ve ever ridden a bike, then you already know that successfully changing gears is vital to a smooth, efficient ride. And when it comes to gear shifting, knowing about gear cables is essential.
What Are Gear Cables?
Gear cables are thin, wire-like cables that connect the gear shifters on your handlebars to the derailleurs or hub gears located on your bike’s frame. When you change gears by moving the shifters, the gear cables lengthen or shorten and move the derailleurs or hub gears, causing the chain to move up or down the gear cassette, resulting in a gear change.
How Do They Work To Change Gears On The Bike?
As you move your gear shifters, gears cables activate the derailleurs or hub gears, which move the chain between the gears in the cassette. The gear cables pull or release tension in the derailleur, causing it to move the chain sideways, up, or down the gear cassette, changing gear ratios.
Different Types Of Gear Cables – Derailleur Cables And Hub Gears
There are two types of gear cables – derailleur cables used in bikes with derailleur gears, and hub gears cables used in bikes with internally geared hubs.
Derailleur Cables
- Derailleur cables are used with derailleur gears on most bikes.
- They give riders a broad range of gears for different terrain types.
- The cables change gears quickly and accurately, making them great for racing and fast-paced rides.
- However, they can be challenging to maintain, as they can become dirty and tangled.
Hub Gear Cables
- Hub gear cables are used in bikes with internally geared hubs, which means the gears are located in the rear wheel.
- They are weather-resistant and low maintenance, making them ideal for commuting bikes.
- They offer fewer gears compared to derailleur gears but give smooth and reliable gear changes.
- They are slightly heavier and can make the bike feel less agile.
Knowing the advantages and disadvantages of each type of gear cable can help you choose the right one for your riding needs. Remember always to keep your gear cables clean, lubricated, and correctly tensioned to ensure a smooth gear change every time.
The Differences Between Bike Brake And Gear Cables
The Fundamental Differences Between Brake Cables And Gear Cables
Bike brake cables and gear cables may look alike, but they have distinctive differences. Knowing these differences can help you choose the right cable for your bike. Here are some key factors that set them apart:

The thicker cable allows for the required braking force, while the shorter length reduces the risk of stretching or snapping. Gear cables, on the other hand, are longer and thinner, allowing for easy shifting between gears.
- End fittings: The ends of the brake and gear cables differ as well. A brake cable’s end is straight, whereas gear cables have a barrel-shaped end fitting to connect to the derailleur and shifter.
How To Differentiate Between The Two Types Of Cables
Identifying brake cables from gear cables is not as tricky as it seems. Follow these simple tips to differentiate between the two:
- Thickness: The thickness of the brake cable is noticeable and sets it apart from the gear cable.
- Color: Brake cables generally have a silver-colored coating, while gear cables can come in different colors.
- Functionality: Brake cables should be connected to the brake levers or calipers, while gear cables connect to the gear shifters and derailleurs.
Similarities Between Bike Brake And Gear Cables
Although bike brake cables and gear cables vary in their characteristics, they share some similarities:
- Material: Both types of cables are usually made of stainless steel or galvanized steel, which are flexible, rust-resistant, and have a long life span.
- Maintenance: Regular cleaning and lubrication of both cables are essential to improve longevity and performance.
