How to adjust the transmission of mountain bike

The adjustment method of mountain bike transmission is as follows:

Tools: wrench, screwdriver.

Equipment: mountain bike.

1. First of all, when installing the transmission, there is a sticker indicating the distance on the new front dial, which can be adjusted according to this sticker. If there is no sticker in the future, you can measure it by hand or ruler and keep the distance from 1 to 2mm.

2. Keep the big tooth plate parallel to the front shift chain plate.

3. Shift the shift lever of the forward gear to 1 and reset the fine-tuning bolt to zero. There are two steps to adjust the forward gear, one is to adjust the inner limit and the outer limit, and the other is to adjust the positioning when shifting gears.

4. Internal limit adjustment: firstly, replace the tooth plate with the smallest tooth plate, and rotate it into the largest tooth plate, and check whether the inner chain guide plate rubs against the chain or whether the gap between the inner chain guide plate and the chain is large. At this time, it is necessary to adjust the screw marked L before to keep the distance from the chain at1~1.5 mm. The chain touches the leading chain plate and can be adjusted to the required distance.

5. External limit adjustment: replace the front dial with the largest toothed disc and the flywheel with the smallest piece, and then check whether the outer chain guide plate touches the chain or the spacing is too large. Adjust the screw marked H to keep the distance from 1 to1.5 mm. If the distance is too large, just adjust the H screw.

6. After adjustment, the mountain bike transmission is adjusted.
