Many riders always envy the riding speed of those riding celebrities, and always complain that they ride too slowly, not enough to ride chic and handsome rides. Don't worry too much about these problems, maybe these problems are the reason why you don't ride fast enough, let's take a look at which ones!
Setting a tire pressure that is too low can have a big impact on your bike and even limit the maximum speed you can ride, meaning that you may have to work twice as hard to catch up with your companion because the tire pressure is too low. 
It's a good idea to check your tire pressure before you travel.
Low tire pressure can lead to a lot of problems. As you ride, the tires continue to release air outward, and the tires under long-term riding will slowly deflate, which is different from a puncture, it will not be completely deflated, but the air pressure is not enough when riding, which will increase the friction with the ground, thereby increasing the riding resistance. It is recommended that you take a little air into the tires when riding. Keep the tire pressure between maximum and minimum.
If you're out for a ride, you're likely to run into headwinds. In fact, headwinds are quite common. However, you can take the opportunity to exercise your strong thighs and build stronger leg strength.
The chain and wheel set of the bicycle also need to be maintained regularly, otherwise it will affect your riding speed and make you more difficult to ride. For example, the smoothness of a chain that has not been lubricated for a long time cannot be compared with those that are often lubricated and maintained. If the wheel hub is not maintained, it will not be as smooth and efficient when riding at high speeds. If you want to ride fast enough, regular maintenance of chains, hubs and other components is a must.
The quality of the brakes is also an element that makes you feel the slower ride. The purpose of the brake accessories is to keep the brake pads as close to the disc or rim as possible to ensure the best braking effect. It doesn't matter if you're using disc brakes or regular V-brakes. In the long run, brake pads can cause scratches and wear on the rim or disc. This can also lead to the culprit of slow speed, you can first check whether the rim is deflection, whether the brake pads are deformed, etc., and if necessary, you can adjust it by fine-tuning.
Road conditions are also one of the factors that affect how fast or slow you can ride, and here we are not talking about the kind of climbs, but we look flat, but when you ride, it feels difficult to walk along this road. You can use computers and other equipment to understand the situation of riding roads, so that you can know yourself and your opponent.
In addition to excluding some of the previous conditions, there will be slow riding, that is likely to be the cause of your own body, it is likely that you lack exercise for a long time, your cardiopulmonary function is not strong enough, this problem is not to change to a more advanced car, find a familiar road can solve the problem, only if you continue to practice, constantly improve yourself, surpass yourself can do it, others are irreplaceable.
