According to Shimano, the biggest difference between these two groupsets is that 105 is 11-speed, while Tiagra is 10-speed. Tiagra offers double and triple crankset options (with three chainrings), whereas 105 only has a double crankset. Many of Shimano's technologies have trickled down from the more expensive Ultegra and Dura-Ace to the 105 R7000, while Tiagra is slightly heavier. More relevant information is as follows: Drivetrain components: The Shimano 4700 groupset and R7000 groupset have always been the most common drivetrain components. Unlike the top-tier DURA-ACE and second-tier ULTEGRA, TIAGRA and 105 are positioned lower with more affordable prices. Drivetrain components include: shifters/front derailleur/rear derailleur/crankset/cassette/chain/brake calipers (or disc brake calipers). Shimano's groupsets are divided into 6 tiers, with the names and model numbers from highest to lowest being: DURA-ACE-9100; ULTEGRA-R8000; 105-R7000; TIAGRA-4700; SORA-R3000; CLARIS-R2000.

I've always used Shimano road bike groupsets, and the 105 series is a cost-effective option, with the R7000 being its specific version update. Simply put, the R7000 has made many small optimizations based on the old 105. For example, the derailleur incorporates a new design, making shifting smoother and preventing hesitation when climbing; the braking system has also been upgraded, offering more responsive performance, especially giving me better control when descending on mountain roads during turns. The weight has been slightly reduced, reducing shoulder fatigue during long rides. It's a bit more expensive, but the parts have broad compatibility, making connections more secure when replacing components. In summary, if you already have the old 105, upgrading isn't a must, but for beginners or those looking to enhance their riding experience, the R7000 is recommended—safe and practical, especially for worry-free night rides.

What to Do When the Car Key Doesn't Work After Just Replacing the Battery?

Smart keys can emit infrared signals, which can unlock one or two doors, the trunk, and the fuel filler cap, as well as operate the car's windows and sunroof. If the car key stops working after replacing the battery, the following situations may occur: 1. Coding failure. The solution is to insert the key into the ignition and turn it repeatedly, being careful not to start the car. After repeating this four or five times, press and hold any button on the key to recode and reactivate it. 2. There may be a leakage fault in the circuit board inside the remote control, or a button may not have popped back up. The engine will only start when the central processor detects that the key is inside the car.

Can You Step on the Accelerator Directly When Starting?

You can step on the accelerator directly when starting. Keep the tachometer around 2000 RPM and gently press the accelerator. Here are some precautions for starting: Start smoothly: During a normal start, ensure the process is smooth and safe, maintain the correct driving posture, avoid looking down at the gear shift, and keep your eyes on the road ahead and both sides. The start should be free from jerking, stalling, or intermittent surging. Coordinate the clutch and accelerator properly when starting: This means learning to use the clutch pedal, accelerator pedal, and brake pedal appropriately during the start. Select the right gear: The gear selection should be based on the car's condition, road situation, and slope. Generally, on flat and solid roads or surfaces, use 1st or 2nd gear to start. In extremely cold weather, on loose soil, or when going uphill, always use 1st gear to start.

Why is the fuel consumption high during startup?

High fuel consumption during startup is due to the instantaneous fuel consumption when the car starts, which can reach 30-40 liters/100km. The fuel consumption then gradually decreases to normal levels while driving. Even rapid acceleration on the road won't result in such high fuel consumption again. Here are some methods to reduce fuel consumption: Clean engine carbon deposits: Excessive engine carbon deposits are a significant cause, mainly due to the use of unsuitable fuel. It is recommended to add a certain amount of cleaning agent when refueling, and after cleaning, it's best to drive at high speed for a while, which helps increase exhaust volume and allows stronger airflow to remove larger carbon deposit particles. Check the oxygen sensor: As an internal control unit of the car, the oxygen sensor mainly monitors the air-fuel ratio of the engine. Once it is damaged, it will cause an imbalance in the engine's air-fuel ratio, leading to a sudden increase in fuel consumption.

Is it harmful to the car if the steering wheel is not straight after parking?

It is harmful to the car if the steering wheel is not straight after parking, and the damages include: 1. Some components such as tires, tie rods, and steering gear are constantly under tension, leading to part aging; 2. Reduced hydraulic pressure in the steering system, resulting in oil leakage symptoms; 3. The vehicle may experience deviation while driving. The reasons for the steering wheel being not straight after parking are: 1. Damage or looseness of chassis components; 2. Improper wheel alignment; 3. Uneven wear of the steering wheels; 4. Deviation in the tie rod ball joints inside the steering gear; 5. Poor parking habits. Solutions for a not straight steering wheel after parking: 1. Tighten or replace chassis components; 2. Perform a four-wheel alignment calibration; 3. Swap the left and right steering wheels; 4. Adjust the tie rod ball joints inside the steering gear; 5. Maintain good parking habits.
