However, they can be noisy and wear down the rotor faster than organic pads.
Organic brake pads, on the other hand, are made of natural materials such as rubber, resin, and kevlar. They are quieter than metallic pads and provide better modulation, which means you can control the braking power more precisely. They are also gentler on the rotor and don’t produce as much heat. However, they wear down faster than metallic pads and are not as suitable for extreme riding.
Brake Pad Materials
Mountain bike brake pads can be made of different materials, each with its own strengths and weaknesses. Metallic pads are made of metal fibers and can be further classified as sintered or semi-metallic. Sintered pads are made of metal particles that are fused together under high pressure and heat. They are more durable than semi-metallic pads and can handle extreme riding conditions. Semi-metallic pads are a combination of metal fibers and other materials such as resin or kevlar. They are quieter than sintered pads but not as durable.
Organic pads are made of natural materials such as rubber, resin, and kevlar. They are softer than metallic pads and provide better modulation. However, they wear down faster than metallic pads and are not as durable.
Choosing the Right Brake Pads
When choosing brake pads for your mountain bike, consider the type of riding you will be doing and your personal preferences. Metallic pads are ideal for downhill and aggressive riding, while organic pads are better for cross-country and trail riding. Consider the weather conditions as well – metallic pads are better for wet and muddy conditions, while organic pads are better for dry conditions.
Also, consider the type of brake system on your bike. Disc brakes use different pads than mechanical or v-brakes. Hydraulic brakes require specific pads as well. Be sure to check the manufacturer’s recommendations before purchasing new brake pads.
In conclusion, understanding the different types of mountain bike brake pads and their materials is important when choosing the right ones for your bike. Consider the type of riding you will be doing, the weather conditions, and the type of brake system on your bike to make an informed decision.
