7S /8S Bicycle Rear Derailleur

If the Bicycle Rear Derailleur does not match the chain for a long time, what impact will it have on riding?

If the Bicycle Rear Derailleur (Bicycle Rear Derailleur) does not match the chain for a long time, it will cause a series of adverse effects on riding. These impacts not only involve riding comfort and efficiency, but may also pose a threat to riding safety. The following are the main specific impacts:
Decreased riding efficiency
A mismatch between the rear derailleur and the chain will result in sluggish shifting, and the rider may not be able to quickly and accurately switch to the appropriate cassette when a shift is needed. This not only consumes more energy, but also reduces riding efficiency, especially when climbing hills or when quick gear changes are required.
Increased wear and tear
A chronic mismatch can subject the chain and rear derailleur to additional friction and wear. The chain can slip on the cassette chainrings, causing accelerated chainring wear; the rear derailleur can also experience additional stress from constantly trying to adjust the chain position, causing its internal parts to wear out faster.
Skipping teeth and chain jams
A mismatch may cause the chain to skip teeth or jam during riding. A skipped tooth is when the chain accidentally comes off the cassette sprockets, while a stuck chain is when the chain gets stuck between the cassette and the rear derailleur and cannot move. Both situations will interrupt the cyclist's normal riding and may even cause the cyclist to fall, especially when driving at high speeds or in complex road conditions.
Increased security risks
Due to unsmooth shifting and possible gear skipping, chain jamming and other problems, cyclists need to always pay attention to the working condition of the shifting system during riding, which may distract their attention and increase safety risks during riding. Especially in emergencies, cyclists may not be able to react quickly, increasing the risk of an accident.
Impaired riding experience
Long-term mismatches can also negatively impact the riding experience. Frequent shifting issues and chain noise can make riding unpleasant and reduce the fun and enjoyment of riding.
Therefore, in order to ensure riding comfort, safety and efficiency, cyclists should regularly check and maintain the bicycle's transmission system to ensure that the rear derailleur and chain are in good condition. If any mismatch is found, adjustments or replacement of relevant parts should be made in time. At the same time, cyclists should also pay attention to the gear shifting operation during riding to avoid excessive wear and unnecessary failures.
