What combination of front and rear chainrings are used for mountain road shifting?

What combination of front and rear chainrings are used for mountain road shifting?

The road is uneven, and it is unavoidable to go up and downhill. Therefore, it is necessary to adjust the chainring to adapt to the riding road conditions. If the rear chainring cannot cope with the changes, it is necessary to consider changing the front gear. If only the front gear is changed, the gear ratio is often too large, and the rear chainring must be changed to reduce the pedaling force.

1.Lower the front chainring, raise the rear chainring

2.Elevate the front chainring and increase the rear chainring.

The left and right gear levers need to be adjusted at the same time until the easiest to operate is selected. Generally, there are two combinations of front outer, rear inner, front outer and rear inner.

That is:

1. Front large chainring + rear large chainring
2. Front small chainring + rear small chainring
Of course, some people do not approve of this combination, because it will cause the chain to tilt, which greatly reduces the transmission function of the chain and accelerates the loss of the chain. In addition, the chain will also rub against the chainring next to it, and the loss is also relatively large.
