Introduction of bicycle crankset
Crankset: The part of the bicycle that connects the bottom axle and the crank. The athlete drives the crank by pedaling, which in turn drives the rotation of the chainring, and finally drives the rear wheel to rotate through the chain and the flywheel to provide power to complete the entire transmission chain of the bicycle.
A number of gears on the crankset: There are three types: single, 2, and 3 pieces.
Installation of bicycle crankset
1. Install the adjuster first (left positive thread, right reverse thread), and tighten it with the tool like a big wrench.
2. Insert the right crankset to match the angle of the opposite crank. If there is a washer, it will be placed in the left crank.
3. Use a gear-like tool to lock the left cover tightly
4. Then tighten the 2 screws on the left crank root. The anti-falling washer is passed through by the screw, and then pressed in, and then 2 screws are locked in. It should be noted that the 2 screws should be locked alternately, not at a time Lock one and then lock the other one.
