How to Shift Bike Gears (and Not Cross-Chain) for Beginners

Avoid drivetrain wear! Learn what cross-chaining is and how to properly align your gears for a smoother, more efficient ride.

Ever notice a weird grinding sound or felt a sudden stiffness when you're shifting? You might be "cross-chaining" without even realizing it. It’s a common habit that quietly beats up your drivetrain over time.

Basically, cross-chaining happens when your chain is pulled at an extreme angle. If you’re on your biggest gear in the front and the biggest in the back—or the smallest with the smallest—the chain isn't running straight. That extra stress wears out your gears way faster than it should. Check out the diagram below to see those angles in action; avoiding these will keep your ride a lot smoother.

What is the effect of using HIGH, MEDIUM, LOW gear combinations?

This is a sample for a 24 speed or 3 x 8 Mountain Bike (MTB).

Proper High Gear Combinations

Heavy in pedaling (low cadence) but bike move fast (normally flat road).

High gear combinations

Proper Medium Gear Combinations

Slight lighter than high gear, but bike move slower (normally leisure ride).

Medium gear combinations

Proper Low Gear Combinations

Light in pedaling (high cadence) but the bike moves slow (normally slope or uphill).

Low gear combinations

Cadence = Pedaling Speed. Pedaling speed is depending on your leg's strength.

Gear Combinations to Avoid

Avoid these gear combinations as this puts additional stress on you bike components.

Gear Combinations For Beginner Riders

Medium gear. Put the middle gear constantly to [2] and just shift the rear gear [4 5 6]. You will feel slightly heavier when you shift the gear from 4 to 5 or 5 to 6.
