How fast is it better to buy a road bike, and whether it is better to have more or less speed on a r

Regardless of mountain bikes.

Or a road car.

The more speed differences, the better, which is mainly reflected in the difference in the number of teeth between the two adjacent teeth, and the less the difference in the number of teeth, the closer to the continuously variable speed.

The difference in the number of teeth of the 8-speed flywheel is more than two teeth, and the highest-end 11-speed flywheel can achieve more than half of the number of teeth to reach one tooth, so the 11-speed flywheel for a tooth will not cause the load to suddenly be too large or too small, as for the gear will become heavier, this is a bit misunderstood, the flywheel will indeed become heavier, but the chain will become lighter, no matter how much speed the crankset is three highways are two, the more speed the thinner the gear, the same is lighter, the more speed the kit materials are more exquisite, The strength and weight will be much better than the speed, so how much speed to choose only depends on your wallet, you get what you pay for.

When it comes to road bikes, how fast you can go depends on your individual needs and budget.

If you're looking for performance and care about the weight and detail of your vehicle, a 24- or 27-speed road bike is a good choice. These vehicles typically have lighter frames and more advanced components that provide better acceleration and cruising performance.

If you're on a budget, or just want to go on a short ride, an entry-level 21-speed road bike might be better for you. These vehicles are usually** more affordable and can meet basic needs.

It should be noted that the shifting effect and quality brought by different brands and models of transmission systems can vary greatly, so it is recommended to check the explanation of the bicycle forum or consult the opinions of a professional before purchasing. In addition, although it is true that the flywheel will be heavier, the chain and crankset will be lighter, so it will not add much weight overall. Therefore, the choice of speed road bike needs to be considered comprehensively according to individual needs and budget.

So far, the most variable gears are 11 speeds, and the most gears on the market are basically three, and the speed is different, and there will be differences, because the speed and front and rear derailleurs are all complete sets, and they are not universal, so they should be based on what they can accept**, to determine the speed they want to buy, the more expensive they are.

The 11-speed is the most widely available spec on the market, so if you want to get it all at once, buy the 11-speed.

Of course, the more speed farewells, the better.

Selectivity is large.

For different pavements and the distribution of physical strength.

Choose the speed that suits you.

I'm a big truth-teller.

You feel like I have a point.

Expand your knowledge: (Take common mountain bikes as an example).

Speed difference refers to the number of different speed ratios between the front crankset and the rear flywheel of a bicycle. For example, if the front crankset of a mountain bike is 3 pieces and the rear cassette is a plate, then the ratio is 3 7 = 21 speeds, 3 8 = 24 speeds, 3 9 = 27 speeds and 3 10 = 30 speeds.

The higher the speed, the more gears he has with his right finger, because he has to make the rear transmission and flywheel work in harmony.

The higher the speed, the greater the number of flywheels, the thinner the thickness of each flywheel, and the smaller the gap. The main reason is due to multiple influences such as frame, rear derailleur, chain, etc.

The higher the speed, the thinner the chain, and a speed-specific chain corresponds to a speed-specific chain, which cannot be mixed. The main reason is limited by flywheel clearance.

The higher the speed difference, the longer the toggle back (the longer the distance between the two introductes) is due to the tension of the chain and the flywheel during the shift.

It is better to buy a 24-speed road bike, and it is easier and faster to adjust.

1. Common mountain bikes on the market are 21-speed, 24-speed, 27-speed and 30-speed.

Background: Born in 1977 in San Francisco, on the west coast of the United States. At that time, a group of young people who were keen to ride beach bikes to have fun on the hillside had a whim: "It would be very fun to be able to ride a bicycle down the mountain." ”

So the design of the off-road bike began, and it was two years later that the official name was mountain bike. Since then, "downhill competition" has emerged as a new sport in sports competitions, where athletes ride mountain bikes and glide downhill along prescribed downhill routes at high speed.

Choose as fast as you want on your mountain bike.

It mainly depends on your own purpose and budget for buying a car.

1. The budget is very sufficient: if there is a competition demand, the 30-speed one is more suitable, the 27-speed one can also be, and now the 27-speed car is very common. Generally repentant walking, pressing the road.

For long and short rides, a 27-speed one is sufficient, and the performance is not bad.

2. Limited budget: to participate in some low-end competitions, such as small competitions of friendship between colleges and universities, etc., a car with a 27-speed 2500 or so is about the same; Ordinary travel, pressing the road, riding on the long and short posture silver road, 24 speed is enough, and about 1500 can be done.

It is better to buy a 24-speed road bike, and it is easier and faster to adjust.

1. Common mountain bikes on the market are 21-speed, 24-speed, 27-speed and 30-speed.

3. The previous 21-speed and 24-speed shifts were almost imperceptible. The current 27-speed and 30-speed are also readily available. It is recommended to buy a 27-speed mountain bike, which can handle almost any surface.

4. If you choose a car at 27 speeds, but different brands, different models of transmission systems, the transmission effect and quality brought by it are simply worlds apart, when you buy more to see the explanation of the bicycle forum, don't be deceived by dishonest merchants.

5. Mainly look at the budget and purpose. 1,000 to 2,000, 24-speed 2,000 up to 27-speed, 24-speed is enough, budget is sufficient and go directly to 27-speed.

Bicycle condition check:

Normal riding use does not require any technology, but in the maintenance of the bicycle, the most important and basic one, before riding, the condition of the bicycle to check, is very important, but also often forgotten, so before riding, remember to do the following checks:

Check your riding position: If you're not riding a bike that you don't own, remember to adjust the saddle to the right height before riding.

Check the tightness of the screws in each part: check whether the quick release of the front and rear wheels and seat cushion rod is locked, check whether the handlebar has been fixed, and whether other screws are loose.

Check the tires: check whether the tire pressure is sufficient, if it is insufficient, hit it to the appropriate pressure, check whether the tire wall is cracked, whether the cut tread is too shallow, and if necessary, replace the outer tire.

Check the brakes: try to pull the front and rear brakes to check whether the brakes can really brake.

Check the front wrist: brake the front brake, shake the body back and forth, if there is a gap between the wobbly and the front wrist must be readjusted.

Check the transmission: After starting, try to change the front and rear gears separately, whether you can smoothly change to each gear, and whether there will be strange noises.
