It is recommended to replace them together.
1. After increasing the speed, the thickness of the sprocket is thinner than before, and the chain is also a little narrower. Similarly, the chainring needs to be replaced to better engage with the chain. After increasing the speed, the chainring of the chainring is too large, and it needs to be replaced with a smaller chainring to reflect more accurate speed changes and the limited length of the chain.
2. Crankset installation:
1. Install the adjuster first (left positive thread and right reverse thread), and tighten it with a tool like a large wrench.
2. Insert the right chainring and align the angle with the crank on the opposite side. If there is a washer, place it in the left crank.
3. Use a tool like a gear to lock the left cover tightly.
4. Then tighten the 2 screws on the left crank root, pass the screw through a washer to prevent falling off, and then press it in, and then lock the 2 screws. It should be noted that the 2 screws should be locked alternately, not at a time Lock one and then the other.
