Question 1: I use a certain speed rear derailleur, a certain type of transmission system. What tail hook should be used?

Answer: The tail hook lifting lug is an accessory of the frame (except for the hook rear derailleur), and has nothing to do with the gear shift and rear derailleur used.

Question 2: My bike is a XX brand frame, which tail hook should I use?

Answer: It is impossible for us to know which tail hook is used for all frames. Please send a picture to us to confirm (the picture found on the Internet, please check whether

it is the same as your own bike tail hook. Some brands may have different tail hooks for different batches)

Question 3: How strong is your tail hook here? Is there any steel?

Answer: Most of the materials used are 6061 aluminum alloy. Why not use steel? Because when you accidentally crash the bike, you may encounter the transmission and cause

deformation to affect the speed function. The rear hook is made of aluminum alloy to allow certain deformation, thereby protecting the transmission from damage. In the event

of a serious bump, the rear hook can be broken, and it can be replaced with a new one afterwards, thereby reducing the cost of frame maintenance. The strength of steel is too

high to provide protection.

Question 4: Is the one you recommended can definitely be used? What should I do if the tail hook I bought cannot be installed?

Answer: As long as the pictures you take are clear and accurate, there is almost nothing wrong with the model number recommended based on our experience. Of course, if there

are any uncertain factors, we will tell the truth, and you will decide whether to place an order. We only promise that the tail hooks sent are consistent with the photos.

Question 5: Why is the quality of your tail hook so bad? Why did it break after just being used. Is there any warranty

Answer: The function of the tail hook is the same as that of a fuse. If there is a problem with the speed change, the tail hook must be broken or stuck. It is especially

reminded that the last tail hook was suddenly broken during riding and must be checked. If the speed problem is not eliminated, the tail hook may break again. If it is broken,

you must also check whether it is smooth after replacing the new tail hook. The tail hook is a vulnerable part and has no warranty. This accessory is not covered by the

warranty for almost all brand vehicles and frame manufacturers. To reiterate the tail hook function is the same as the fuse, the fuse is blown due to a short circuit, you

should check why it blows, instead of blaming the fuse for poor quality.
