1.What is road bike disc brake?

The basic difference between a traditional rim and a disc brake is where the braking force is applied. Just the name alone shows that difference. Rim brake means that the brake pads clamp directly to the rim to generate braking force, with this mechanism the rim is an important structural part of the base wheel and is the main contact surface that directly affects the brake. .

Road disc brakes are of two types: mechanical and hydraulic

In contrast, the disc brake will be able to move all the functions of the brake to a much smaller diameter rotor attached directly to the center just like the disc brake in an everyday car or motorcycle. The rim brake is mounted on the chassis and fork but it is closer to each wheel axle.

One important difference is how each brake type is normally operated. With a few exceptions to the rim brake, the use of cables for activation means leveraging a steel cable inside a case, as it has been for many years. You only need to pull the brake lever and then pull the lever toward the handlebar, the brake pads can be clamped to the rim.

Disc brakes are more often hydraulic, where cables and covers are often replaced by an uncompressed liquid and a hose in a closed system. When you use pull the lever onto a hydraulic brake It pushes the plunger into the master cylinder, then pushes the liquid through a conduit to the other end. The hydraulic pressure is the force that pushes the pistons of the cylinder tube out and clamps to the rotor gaskets.

2. Why is a disc brake better than a rim brake?

First, disc brakes can produce more stopping power to the wheel, meaning that the operator will need to apply less force at the lever to be able to provide brake contraction assistance. The racer has to use more force even grappling to be able to create more force to have enough power exerted on the rim brake.

Bicycle disc brakes are made from a much stiffer metal material

An added plus is that the braking power can be quickly and fairly easily increased by changing the size of the rotors as you like. A larger rotor wheel will increase the mechanical leverage, while a smaller rotor wheel will save a decent weight for the rider.

Adjust the brake by changing the rotor size

Disc brakes that offer better modulation than rim brakes also mean it’s easier for drivers to measure the accuracy of how much pressure is applied. occurs before the lock on wheels fitted with better discs. The brake disc also tends to be linear and also predictable on rim brakes and it is much more suitable in different weather conditions, especially when compared with the use of brakes on carbon rims – a combination It offers poor performance in wet conditions and can easily get hot in dry weather.

All of these advantages have been boosted on hydraulic disc brakes, which can reduce power and lever losses more than rim brakes with the cable controller.

Especially in these early days of bicycle racing disc brake When using the rim brake, you still have to hold your hand in some key areas. While the disc brakes are not a weight-wise choice, compatible wheels, frames and discs are also heavier. On average, a bike with good brakes will weigh around 500g (a pound heavier) than the disc and that’s a premium example.

Sticking only to the front of the performance, the disc brakes are less aerodynamic than the rim brakes although the accuracy of that difference is still debatable.

The simplicity of the cable drive system also has a lot of advantages. Parts are usually cheap and very popular, there is a very high degree of compatibility between many brands and repairable systems. It is easier when needed, even if it breaks down in the middle of the road with no one to help.

Finally, an aesthetic issue, the rim brakes don’t seem as elegant as the disc brakes. But each has their own choice.

3. How to change the disc brake on Roadbike?

Other conspiracy theories aside around why in some cases the disc brake surface becomes too hot. There are major changes in bicycle technology and making the buyer more persuasive.

The disc brakes are properly designed to avoid affecting the geometry of the frame

The fact of this problem is that the bicycle industry is gradually improving its technology to build and manufacture bicycles. Bicycles are equipped with better and safer brakes.

As mentioned above bikes with heavier hard disks and less aerodynamic than those that are comparable to rim brakes but for many riders different freedoms are provided by way of Switch to disc brakes rather than make up for the failures.

Without worrying about supplying a screw, road bikes provided with disc brakes could easily fit better with large tires and larger rims for improved traction. on more diverse mixed terrains. Since the saddle has to be reinforced to accommodate the brakes, they can be more flexible.

Wheels are further reinforced and improved when using disc brakes

The wheel will probably change and improve more when switching to the disc. Without the use of rim brakes, the rims will be improved with more design to ensure aerodynamics and we often see riders choose more carbon rims and they do not have to worry about the problem of hot rims. again.

With the desired one can move with the accompanying brake disc through an axle. While disc brake installation can be much faster through wheel detachment, there are still many wheel changes to better fit the frame and fork fork. This can lead to problems such as rubbing the rotor wheel, causing the brakes to be terribly hard.

The axle provides a better stable and protected position

We are also hoping that manufacturing companies will continue to find a way to incorporate brake discs into the design of bikes that not only narrow the performance gap when dynamics, but also help reduce weight of vehicle. Keep in mind that these are the early stages of disc brake technology and there is no doubt that things will evolve in the future.

4. Compatibility and standards issues

Disc braking is probably a rump in racing bike compatibility compared to existing rim brakes. Disc brakes not only require specialized accessories on the chassis, forks, and parallel tubes that are ideal for installation. Whereas the wheels require an interface shaft to mount the rotors.

The axle is required to be compatible with the rotor

The methods by which specific disc components are attached to the bike remain in the stream. Although there will be indications that the industry is planning to design a 12mm diameter shaft and brand new drum standards have yet to be established. Such stability will benefit racers or riders. Bike enthusiasts in general have plenty of reasons to look forward to.

There’s hardly any mix or match between brands of disc brakes, at least as well as hydraulic brake options. While there will be a bit of flexibility for combining different vehicle models and models between rim brakes, especially when you use smaller brands, the disc brakes are a lot more restrained.

An example such as hydraulic SRAM disc brakes that can only be combined with SRAM levers, active disc brakes from TRP, SRAM / Avid, Hayes and others can give you more flexibility but even more. is then there should be difference in cable pulling ratio between different models.

5. Ability to maintain

The hydraulic disc brake system has long been widely accepted in the mountain climbing market and is now available on Road bikes. Most of the brakes to maintain good performance require daily maintenance. The rotors cleaning also needs to take place regularly to get the best surface working effect. In addition, should replace fluid in hydraulic brake about 2 times / year for smoother operation.

Disc brakes require specialized repair and maintenance tools. Also, tend to be more expensive during disc-pad replacement, but the difference to the rim brake is in fact a rather large lifespan.

You can completely replace the rim brake for the bike. That’s probably not because at least rim brakes will exist with smaller brands and they have a more common compatibility than disc brakes.

If you are wondering about choosing a sports bike or planning to upgrade your bike, consult with top cycling experts and experienced motorists to choose. get the car, kind of brake like that.
