# How To Know What Gears To Use On A Mountain Bike?

Mountain bikes have lots of low gears so that you can easily climb steep hills.

Road bikes have more higher gears, which can boost top-end speed.

This is why they’re often called “entry-level” bikes.

There are more gears to choose from, but riders have to do a little more work to get the right gear combinations.

## How do I know my bike gear ratio?

– Gear Ratio = Number of Teeth in Chain Ring ÷ Number of Teeth in Rear Cog.

## How do I know if my cassette is 11 speed?

The number of teeth on the cassette determines the number of gears the cassette can shift through. For instance, if the cassette has 28 teeth, it can only shift through a two-speed setup. However, if it has 32 teeth, it will have the capacity for a three-speed setup.

## How are bike gears numbered?

Bikes generally have 1, 3, 18, 21, 24, or 27 speeds. The lower the number on the front of the cassette, the lower the gear is. Also note that 10- and 15-speed cassettes are obsolete and you don’t see them on new bikes anymore. The number refers to the number of teeth on the sprocket. The higher the number, the higher the gear. First gear is a low gear.

## How do I know what gear ratio My bike has?

If you’re interested in learning more about the parts of your bicycle, there are numerous websites that can help you understand what you’re looking at.

## How do I know what gears to use on my bike?

When you are riding uphill or into a headwind, you should use the small or middle front chainring and larger rear cogs. Otherwise, you will get an overspeed, which will cause you to lose momentum and potentially crash. When riding downhill, you should use the bigger front chainring and a range of the smaller rear cogs.

## What is the difference between 11 28 and 11 32 cassette?

The difference in rpm between the 11-32 and 11-28 cassettes is 10 rpm. This can be important if you’re riding at a low speed, and you want to be able to climb hills.

## How do I know if my bike is 10 or 11 speed?

The number of gears on your bike will be denoted by the numbers on the front and rear gears. If the front gear has an odd number, such as 11, multiply the front gears by 2 to get the rear gear, or if the front gear has an even number, multiply by 10. So if you have a 10 speed bike, the front gear is 10 and the rear gear is 10, which is 100.
