What to Look for Before Buying?
After going through the review section, things must be much more manageable for you. But it can certainly get much easier. However, for that to happen, you would need to consider these factors in your mind:
Before anything else, consider the construction material. Usually, brands will opt for regular polyester cord material for the belts. We are not stating that polyester belts are not great. They last reasonably long and will perform well if the build quality is up to the mark.
However, some of the options out there will utilize highly durable materials, such as X3N carbon. They are highly durable and capable of going through a high level of load, and they will last much longer than the regular materials.
Even with high-quality material construction, the belt might be highly prone to snapping and getting worn out. It will basically happen when the strength of the belt is not up to the mark. So, if you want to get an extended use, we would highly recommend putting the strength on the top of your priority list.
Many riders think that flexibility is not that important. However, it is! If the belt does not have a proper level of flexibility, you will have a tough time trying to slide it onto the drive slots.
On the other hand, if the flexibility is too high, the unit will be highly prone to stretching or shrinking down. And when one of these two happens, the belt will lose its functionality. For that reason, it is pretty essential to choose a belt that has the right amount of flexibility.
Next, check the fitment. In this case, you would need to consider the model of your bike first. Keep that in mind and check whether or not the belt you are getting has the right size, width, and pitch that your bike’s drive requires. If you happen to get something that is not compatible, making it fit will be a big hassle.
Sometimes, the right fitting parts will make you go through tons of hassles when it comes to installing them on your bike. The same thing is applicable for drive belts. Because of that, it is pretty important to check whether the installation process of the belt is simple and hassle-free or not before purchasing.
Difference between a Chain Drive and Drive Belt
Chain drives and belt drives do sound pretty similar. For that reason, many of the new riders get confused among these two. However, there is a good amount of difference between them. And among all of the things that sets them apart, these are the main highlights:
Chain drives are made of steel and metal. On the other hand, drive belts will primarily be made of rubber and carbon fiber. Steel and metal are more durable than rubber and carbon fiber. For that reason, chain drives will last longer than drive belts.
The chain drives are undoubtedly durable and will last longer than drive belts, requiring more maintenance. You would need to get them lubricated from time to time if you want to make them operate optimally. And if you don’t, they will get stuck and make your bike fully inoperable.
In comparison, drive belts require a minimum level of maintenance. They do not need that much lubrication, nor will you need to worry about them getting tangled or stuck while riding your bike.
When you put chain drives and drive belts head-to-head, you will find that the drive belts offer better overall performance. They are quieter and make the bike operate smoothly. On the contrary, chain drives make a good amount of noise during operation. They are not that smooth as well.
