With current pandemics like the domino effect, many road races and cycling events have been cancelled. Everyone knows that exercise improves immunity, but at-home exercise is a good alternative because it increases the risk of crowded sports. Cyclists should be familiar with cycle trainers. It takes more time to prepare and train than running. A full-fledged cycle trainer may be a love-hate partner.
This time, I would like to introduce you to the cycle trainer
Does the cycle trainer hurt the cycle? For many cyclists, one of the questions before buying a cycle trainer is whether it will hurt your favorite bike. Many people think this is nonsense, but I think that the bike trainer fixed to the frame puts more stress than normal riding, and the frame is not so sturdy, so the frame may be damaged. There are also people.
In fact, the problem of cycle trainers scratching their bikes is not only mentioned in word of mouth between cyclists, but also in the explanation of maintenance of major brands. For example, brands such as Specialized and Trek have clearly defined in their maintenance specifications that damage caused by a bike trainer mounted on a carbon bicycle frame is not covered by the warranty. In response to this issue, Swift also summarizes the relevant warranty specifications of major brands for bike trainers on its website. See below for details.

But don’t worry too much. The Cycling tips website interviewed various brands on this issue. Brands are more concerned about bike damage when disassembling or assembling the cycle trainer than overusing the bike frame while working. The manufacturer believes that the bike can be damaged due to improper installation (over-loose or over-tightened, improper quick release, etc.)
In short, we know that, if used correctly, cycle trainer damage is essentially non-existent. Rather, it’s important to note that sweat can damage the metal parts of your cycle trainer. Sweat accumulated in the room accumulates on the bicycle and is prone to corrosion. Of course, you can minimize the risk by wiping the bicycle and performing maintenance. If you still have doubts, choose an older road bike. Alleviates the worries that occur while riding.
Things to keep in mind when training with a bike trainer
Generally, commercially available cycle trainers can be divided into three types: roller trainers, frictions, and direct drive types.
As the name implies, a roller trainer is a trainer that puts a bicycle on a roller stand, and this roller functions as a “treadmill”. The friction trainer puts the rear wheels on the table and gives resistance to the tires. A direct-drive trainer is a drive resistance unit that eliminates the need to use rear wheels. In addition, there is little wear on the outer tube, the rear wheels are removed, the frame is directly connected, and it is driven by a chain.
Among them, the roller trainer is very popular
Among cyclists because it can be used anywhere without disassembling the bicycle. It is often used as a means of warming up before the race. You need to keep your balance when riding the roller trainer. You can simulate the actual road conditions well, and also give feedback and practice getting off the saddle. However, using a roller trainer requires some practice and adaptability. It is difficult for beginners to use because it is easy to fall if you make a mistake.
The bikes on the other two cycle trainers
are fixed and basically similar to a flywheel in the gym. It’s easy to use even for beginners because you don’t have to worry about the balance.
The most common are friction trainers, which have the advantage of being cheap and have many options.
Since the direct drive trainer uses the chain as a direct resistor, it requires relatively little noise and vibration.
There is a more important issue than choosing any cycle trainer.
It is the moment of inertia. On a real road, the law of inertia works, so the trainer finds it easy to pedal and the bike moves forward without having to press hard.
The moment of inertia on the bicycle trainer simulates the inertia under real road conditions. The larger the moment of inertia is assumed, the stronger the simulated force will be and the closer. It will be to the actual feeling of riding a bicycle.Without inertia, the problem of “heavy one leg and light one leg” is likely to occur, so major manufacturers are adding heavier, larger diameter inertial wheels to increase the moment of inertia. In addition to the conventional inertial wheels, heavier wheels and outer tubes can be prepared to increase the moment of inertia, allowing the actual road surface to be reproduced more faithfully.
In today’s era when power training is the mainstream
it is a big trend to have a power meter function. Even if you don’t have a power meter, it’s a good idea to buy a sweatshirt for your power bike that can change your resistance. The main reason is that the combination of intelligent variable resistance capabilities and training software (like Swift) allows you to more effectively simulate real resistance. Erg mode allows you to get more effective and intense training.
