The basics of bike shifting

gear shifting

Along with your brakes, shifting your gears is one of the fundamental mechanical functions of your bike. Learning how to shift may seem basic, but gearing practice and shifting efficiently is something that even veteran riders can work on.

Proper gearing will not only improve your speed, it will also make the ride more comfortable and increase your endurance on longer rides.

1. The Gears

Most bikes have two or three chainrings in the front and anywhere from 7 to 11 gears, or cogs, in the back. Moving the chain from the smallest rear cog to the largest eases your pedaling effort incrementally. Moving it between the chainrings in the front results in a more noticeable change—pedaling feels easier in a smaller chainring and harder in a bigger one.

2. Shifter Savvy

The left-hand shifter changes the front gears; the one on the right controls gears in back. If you get flustered on the fly, remember: RIGHT = REAR.

3. It’s Okay To…

• Use only the rear cogs and the small or middle front chainring when you’re just getting comfortable on a bike.

• look down to see what gear you’re in.

• shift whenever a more experienced rider does.

4. When to Shift

The reason bikes have gears is so you can pedal (relatively) comfortably no matter what the terrain. Shift to an easier gear on climbs or when you’re riding into the wind. Use a harder gear on flats or if the wind is blowing from behind. When in doubt, shift before the terrain changes. When you shift, ease up on the pedals, especially on hills; if you’re pushing hard, the chain may skip or fall off.

5. Avoid Cross-Chaining

That means the chain is at an extreme slant, either in the big ring up front and the biggest cog in back, or the small ring up front and the small cog in back. This not only stresses the hardware, but it also limits your options if you need to shift again.

6. Cheat Sheet

For: Uphills and headwinds

Use: Small or middle front chainring + bigger rear cogs

For: Downhills

Use: Large front chainring + a range of rear cogs

For: Flat terrain

Use: Small or middle front chainring + ­smaller rear cogs
