How To Adjust Derailleur On Mountain Bike?

Why does my chain slip when I pedal hard?

Most of the time, a skipping chain is caused by cable stretch. In the first half dozen rides on a new bike your shift cables stretch the most. They can also stretch over time as you ride. Hippley explains, “It takes cable tension to open a derailleur, which shifts your chain between gears.

Why is my bike not changing gears?

Stop shifting when you find an issue, but keep your bike in that gear. Loosen your cable adjuster if the chain won’t shift down. If you need to make a large adjustment, thread the adjust into derailleur, shift into the smallest gear, loosen the pinch bolt, and pull the cable by hand.

How do I adjust the tension on my derailleur?

Adjust the cable tension Turning the adjuster anticlockwise increases tension on the cable, bringing the derailleur closer to the wheel; clockwise decreases the tension, moving it back towards the frame. If the chain seems hesitant to shift up, increase the cable tension by turning the barrel adjuster anticlockwise.

How often should I change my bike chain?

To avoid this accelerated wear of your cassette and chainrings, a general rule of thumb is to replace your bike’s chain every 2,000 miles. Mind you, this is just a starting point. No two chains will wear at exactly the same rate because no two riders treat their chains the same.

How do I know if my bike chain is too loose?

Check your chain out. It should be tight enough that it only allows you to move it up and down about one inch. If it is sagging or much looser than that, you need to tighten that chain up. Chains often loosen when a bike does not have a derailleur.
