# How can I tell number of speeds on my road bike? 9, 10, 11?

5 min read

##### Asked by: Corey Michelini

**Multiply the front gear number by the rear gear number** to get the number of speeds. For example, if you have two front gears and five back gears, you have a 10-speed bike.

## What is a 11 speed bike?

The rear cassette is 11 speed 11-32. This means there are **11 cogs ranging from 11 teeth up to 32 teeth** (the exact cogs are 11/12/13/14/16/18/20/22/25/28/32). The combination of your selected chainring and cog determine the gear ratio.

## How do I know if I have an 11 speed cassette?

Quote from video: *Numbers if you've ever wandered through your local park shop you may have noticed these numbers on the little cassette boxes 1125 11 28 maybe even 1140. – numbers mean it. All comes down to gearing.*

## What is the difference between 9 speed and 11 speed?

**A 9 speed cassette has larger steps between gears than an 11 speed**, which means that you may need to pedal at a faster or slower cadence to maintain your speed or pedal a bit harder or softer to maintain your cadence than you would with an 11 speed cassette.

## What does 9 speed mean on a bike?

When magazines and websites talk about a bike’s ‘speed’, it’s a reference to the number of sprockets. **A bike with three chainrings and nine sprockets** is 9-speed, even though it has 27 theoretical ratios. The higher the sprocket count, the more expensive, smoother shifting, and lighter weight the gears.

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

**Multiply the front gear number by the rear gear number to get the number of speeds**. For example, if you have two front gears and five back gears, you have a 10-speed bike. If you have one front gear and three back gears, you have a 3-speed bike.

## What is a 10 speed bike?

A 10-speed bike is **a type of road bicycle that allows you to change the pedaling resistance through a shifting mechanism**. The various gears provide up to 10 different resistance settings, or speeds. This type of bicycle engineering makes riding on hilly terrain over long distances easier.

## How do I know what speed cassette is on my bike?

You can know what cassette to get for your bike by **determining the teeth count on the largest sprocket and the smaller sprocket of your current cassette**. For example, a size 12-25t cassette, which is standard to road bikes, has 12 teeth on the smallest cog and 25 teeth on the largest cog.

## Can I use an 11 speed cassette on a 10 speed bike?

**You can use the 11 speed wheel with the 10 speed bike, so long as you use a 10 speed cassette and the right spacers**. It’s usually cost prohibitive to upgrade from 10 speeds to 11. You need new shifters, new derailleur, new cassette, new chain.

## What do numbers on bike cassette mean?

A cassette may therefore be sized as 11-32t. The first number refers to the number of teeth on the smallest sprocket (the highest gear, for fast pedalling at speed) and the second number to the biggest sprocket (the lowest gear, for climbing hills).

## Can I use an 11 speed crank on a 9-speed bike?

Secondly **a 11spd Crankset will work with your 9spd set-up**, but you will need to run a 10spd chain which will work on the 11spd Crank and 9spd Cassette.

## How do I change my 9-speed bike to 11 speed?

Converting a 9-speed wheel to 11-speed

You will have to **buy a new 11-speed wheel and replace the entire wheel**. On the other hand, if your current wheel is an 11-speed wheel, you can convert it to 11-speed by removing the low spacer from the low side of the 9-speed sprocket and installing an 11-speed sprocket.

## Can you use a 11 speed chain on a 9-speed cassette?

Because the INNER spacing of chains remain the same for different speed classes of chains, **an 11s chain will run on 9s chainrings just fine**.

## How do you read bike gears?

Quote from video: *If your chain ring has 34 teeth and your biggest cog at the back also has 34 teeth that is a 1 to 1 gear ratio a relatively easy gear to turn the rear wheel will turn once for every pedal stroke.*

## What is the difference between 10 and 11 speed derailleur?

the 10 speed and 11 speed derailleurs are interchangeable as far as the shifters go, the difference is that **a 10 speed derailleur doesn’t like a cassette cog much bigger than the 36t it was designed for, where the 11 speed derailleurs are designed for 40 and 42t cogs, and seem to be able to handle bigger**.

## How many speeds do I need on a bike?

A single speed is enough for bike commuting on flat or mild terrain, but choose at least 3 speeds to deal with headwinds, heavy loads, and mild climbs. If your commute is hilly, then opt for at least 7 speeds. If your commuting bike will be used off-road, then get at least 9-11 speeds on an extra-wide-range cassette.

## Is 1X11 enough for gravel?

1X11 for gravel. **Gearing is just low enough to get up anything steep and high enough for everything except the biggest descents**.

## How many speeds should a road bike have?

A road bike will have either a triple, double or compact crankset. This refers to the number and size of chainrings (located by the pedals). A triple crankset has 3 chainrings; it is often paired with a 9-speed cassette on the rear wheel to give it a total of **27 gears**.

## What is 1X11 drivetrain?

Simplicity – the 1×11 drivetrain has **a single shifter and no front derailleur**, so there’s far much less equipment to adjust, and thus becomes a bigger time-saver. There are also fewer parts that are likely to fail. We can use every gear combination – unlike the 2×11, where some gears overlap.

## Is 1×10 enough?

**1×10 is not good**, range is too small, difference in weight isn’t worth it and it’s not that cheap especially if you add things to make it better like chainguide, clutch mech, nw ring and larger cassette cog. If you want to go 1x, I’d definitely recommend SRAM because it’s the only good way to get proper range.

## Is 1x Good for uphill?

2x gives you a wider range and makes it easier to tackle steep climbs, while the **1x is much easier to operate and is less prone to chain drops**.
