Why does my mountain bike keep jumping gears?

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. Shift down into the smallest ring in the rear cassette again, and press your shifter again to see if the bike shifts properly.

Can you hit jumps on a mountain bike?

Check your bike: It’s important to make sure you have a mountain bike that’s designed to handle jumping. While suspension is not absolutely necessary, most riders enjoy either front or full suspension to absorb the impact of landing a jump.

What are the gears for on a mountain bike?

Broadly speaking, mountain bikes have lots of low gears so you can climb steep hills more easily, while road bikes have more higher gears to boost top-end speed. More gears means more choices, but also more complexity for riders (and shop techs).

Can you jump on a hardtail?

Hardtails are great for jumps. You can boost on the way up. They’re more sensitive to the transition when you land, though. There’s a reason that dirt jump and trials bikes are hardtails and AM and DH bikes are (mostly) full-suspension.

What to know before jumping a mountain bike?

Avoid department-store brand bikes with cheap components that aren’t built tough enough for jumping. It’s also a good idea to make sure your mountain bike is in good working order before you head out. Always check the ABCs (Air, Brakes, Chain) before every ride.

What causes a bike chain to jump gears?

I show the most common causes for chains that skip, slip, jump gears while pedaling (auto-shifting/phantom shifting derailleur), especially while under torque like climbing up a hill or standing on the pedals. And explain what needs to be done to fix them.

What kind of gear does a mountain bike have?

The most common gear configurations for modern mountain bikes include one or two front chainrings. Bikes with single front chainrings are referred to as “1x” or “one-by”. Whereas you’ll see bikes with two front chainrings abbreviated to “2x”.

When to shift gears on a mountain bike?

Shifting in advance of hard climbs is recommended While still pedaling, slightly ease up your stroke. Click your shifter once to make a single gear change. Continue pedaling through the shift until it completes. Do not stop pedaling or push really hard while the chain is transitioning to the new gear.
