What types of bicycle spare parts are there?

When it comes to maintaining, improving or repairing your bike, choosing the right parts is crucial. Whether you're a road rider, mountain bike enthusiast or e-bike user, each component has a role to play in ensuring your comfort, safety and and your performance. Here's a rundown of the most common bike parts and what they're used for. They're all available on 50factory.com !

The main categories of spare parts

There are a huge number of bicycle parts, but they can be divided into a few broad categories. These components are essential to ensure the proper functioning of your bike:

• Transmission : These are the parts that allow you to transmit your pedaling power to the rear wheel. Among them, we find the derailleurs, chains, cassettes, and cranksets. They directly affect your ability to shift, accelerate, and tackle climbs.

• Brake : Braking systems are essential to ensure your safety on the road. Whether you opt for disc brakes, brake pads or cable and housing systems, it is important to choose the right parts for your bike for responsive and powerful braking.

• Wheels and tires : Wheels and tires are the foundation of any good bike. A well-maintained wheel and a tire that is suited to your riding style provide better grip and a smoother ride. At 50factory.com, you will find a wide selection of wheels, rims and spokes to suit all terrains.

• Accessories and components : From the seat post to the stem, including par Grips, handlebars, and pedals, these elements contribute to the comfort and safety of your bike. A good choice of saddle can prevent pain during long rides, while efficient lighting is essential for riding safely at night.

TRANSMISSION PARTS

La transmission is the heart of your bike. It is responsible for shifting gears and transmitting the force from your legs to the rear wheel, to allow you to move forward smoothly. Each component in this category plays a key role in ensuring smooth gear changes smooth and efficient. Here are the essential components of the transmission and their role:

• Derailleurs : The derailleur guides the chain over the various sprockets of the cassette at the rear or the chainrings at the front. They allow you to change gears by moving the chain over the rear cassette or the front chainrings. A well-adjusted and quality derailleur ensures precise and fast gear changes, which are essential for smooth riding, whether on the road or mountain biking. Brands like Shimano offer derailleurs adapted to each type of practice, offering precision and robustness.

• Derailleur hangers : Derailleur hangers play a crucial role in the smooth running of your drivetrain. They connect the rear derailleur to the frame. They hold the drivetrain in place and prevent it from breaking if there is an impact. If necessary, they can break off to protect the frame. We offer a variety of derailleur hangers that are compatible with different bike brands and models to ensure smooth and precise shifting.

• Chains : The chain is the link between the crankset and the cassette. It transfers the power of your pedal strokes to the rear wheel. It is important to choose a chain compatible with the number of gears on your cassette to avoid chain drop. A well-maintained chain extends the life of your entire drivetrain. We offer chains of different brands and models, suitable for all types of bikes, as well as quick releases for easy installation and replacement.

• Cassettes : The cassette groups together several sprockets of different sizes, allowing you to adjust the development of your bike according to the terrain. Thus, the cassette determines the number of gears available on your bike. The more sprockets there are, the more possibilities you will have to adjust your effort on both climbs and descents. A cassette with a wide range of sprockets is ideal for difficult climbs, while a tighter cassette will be suitable for the road and flat courses.

• Pedals : Cranksets come in a variety of designs, from those designed for mountain biking to models for road bikes. A good crankset provides better power transmission, for smooth and efficient pedaling.

BRAKING PARTS

Braking is one of the most important elements for the safety of a cyclist as well as that of other road users. Depending on your type of bike and your practice, you can choose from several types of brakes :

• Disc brakes : Known for their power and reliability, disc brakes are particularly suited to wet and muddy conditions. They offer powerful, progressive braking and require little maintenance. They are an ideal choice for high-end mountain bikes and road bikes. However, they require specific components such as suitable rotors and calipers.

• Brake pads : If your bike has rim brakes, brake pads are a key part of your braking system. They provide direct contact with the rim to slow or stop the bike. Brake pads should be changed regularly to ensure effective braking and prevent damage to the rims. Pads are easy to change and are often more cost-effective than disc brake systems.

• Cables and sheaths : Don't neglect your brake cables and housings! They are essential to ensure smooth transmission of your pressure on the brake lever to the brakes. A worn cable can compromise the responsiveness of your brakes. Cables in good condition ensure responsive and precise braking.

At 50 Factory, we offer a wide selection of products suitable for different braking systems, thus guaranteeing your safety during every outing!

THE WHEELS ET THE TIRES

Wheels and tires are critical components of your bike's performance and comfort. They affect speed, grip, and rolling resistance:

• Wheel : The choice of wheel depends on the type of bike you are using and your riding style. For a road bike, light and stiff wheels allow for greater speed and maneuverability. For mountain bikes, wheels must be more robust to absorb shocks and provide good traction on rough trails.

• Tires : The tire is the only point of contact between your bike and the ground, so it is crucial to choose a model that is suited to your practice. 50factory.com, we offer a range of tires for every need, whether it's slick tires for the road, knobby tires for mountain biking, or reinforced tires for electric bikes.
