First, adjust the front gear to the minimum gear position.
Because of the angle of shooting, it seems that it is not parallel, actually parallel.
After that, stir the pedals and let the bye turn after the teeth. Toggle finger dial, upper middle tooth platter.If the chain is not smooth, then counter-clockwise to select the dial on the front of the adjustment screw 1/4 weeks, and then back to the smallest tooth disc gear, and then into the middle of the tooth disc (just on the chain of gear), observe whether the chain smooth, if not smooth, press the red text and then adjust. If the smooth, then adjust the maximum tooth disc gear, the adjustment method and the previous adjustment method is the same.
Here need to note: Adjust the dial adjustment screw, can only rotate 1/4 weeks at a time, so slowly fine-tuning, not too much adjustment.
Adjust the speed, then adjust the h screw.
