What effect does excessive chain tension have on the Front Derailleur?

Excessive chain tension means that the chain will exert greater pressure on the Front Derailleur during the transmission process. This additional pressure causes various components of the Front Derailleur, such as pawls, springs, bearings, etc., to bear greater loads. Long-term operation under such high loads will accelerate the wear of these components and shorten the service life of the Front Derailleur.
In addition to accelerated wear, excessive chain tension may also increase the risk of damage to the Front Derailleur. During the shifting process, an overly tight chain may exert excessive impact force on the Front Derailleur, causing the Front Derailleur to deform, break or damage. In addition, if the chain breaks due to excessive tension, the broken chain may hook the Front Derailleur, further exacerbating its damage.
Excessive chain tension can also have a negative impact on the shifting performance of the Front Derailleur. An overly tight chain may limit the range of movement of the Front Derailleur, making it difficult to accurately push the chain to the target sprocket. This can lead to problems such as uneven shifting, shifting failure or chain falling off, seriously affecting the rider's riding experience.
Too tight chain tension may also cause abnormal noise and vibration during riding. These abnormal noise and vibration will not only reduce the comfort of the rider, but also may cause additional stress and wear on other parts of the bicycle. For example, abnormal noise and vibration may accelerate the wear of components such as bearings and chains, and may even cause other components to loosen or damage.
In order to avoid the above negative effects of excessive chain tension on the Front Derailleur, riders need to check the chain tension regularly and adjust it as needed. When adjusting the chain tension, make sure that the chain is neither too tight nor too loose to maintain good shifting performance and extend the service life of the Front Derailleur. In addition, riders should also clean and lubricate the chain and Front Derailleur regularly to reduce wear and extend service life.
The effects of excessive chain tension on the Front Derailleur are multifaceted, including increased load and accelerated wear, increased risk of damage, affected shifting performance, abnormal noise and vibration, etc. Therefore, riders need to check the chain tension regularly and adjust it as needed to ensure the healthy operation of the bicycle's transmission system.
