How Do I Know What Size Road Bike Cassette I Need?

How do I know what size road bike cassette I need? The rule of thumb for choosing the right bike cassette is that the closer the number of “teeth” from the largest and the smallest cogs, the smaller the variation between gears, which ensures a smooth gear change.

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

In the event you find yourself grinding up a hill at 7 mph, the 11-32 cassette allows you to ride at 81 rpm, while with the 11-28, you'll be riding at 71 rpm. One final thing to note: The 11-32 cassette needs a longer cage derailleur and a longer chain than the 11-28 cassette.

What does an 11-32 cassette mean on a bike?

That means the outer ring has 50 teeth and the inner ring has 34 teeth. 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).

Is an 11 34 cassette good for climbing?

All other things being equal, the 34T sprocket on the 11-34T cassette is going to give you the easiest gear. If your bike is currently fitted with an 11-28T cassette, switching to an 11-34T cassette will make climbing less of a struggle.

What is a 12/25 cassette?

A cassette is the collection of sprockets on the hub of the rear wheel. Most road bikes come supplied with a 12–25T cassette, where the smallest sprocket has 12 teeth and the largest sprocked has 25 teeth.

Is 11/32 cassette Good for hills?

Most riders can get away with a compact chainset 50 / 34 and an 11 – 32 cassette for their steepest hills. Many touring bikes and tandems still use triple chainsets, but they often have heavier loads to haul.

Can a 11/32 cassette fit?

11-32 does make a substantial difference; remember its the ratio of the front gear to the rear gear that matters. Your lowest gear will be 12.5% lower. Also, you'll get a wider (and likely more useful) spacing in gearing between changes. You will need a new chain as well, but it should be fine to install.

Can I put a bigger cassette on my bike?

What is the difference between a 10 speed and 11 speed cassette?

10 speed stuff is going to be harder and harder to get parts for over time because it's not the current technology. 2. Tighter spacing on cassettes AND wider range from top to bottom of cassette are possible in the same cassette with 11 vs 10. This can make a pretty big difference when climbing.

How do I know my cassette size?

Sprockets vary in size according to the number of teeth they have. 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).

Is a 12/25 cassette good for climbing?

The vast majority of road bikes come with a 12-25 cassette, which is suitable for most cycling terrain when paired with a compact or standard chainset. If you ride a lot of hills or struggle with hill climbing, a cassette with a lower ratio largest sprocket (27 or more teeth) may be beneficial.

Can you use Ultegra cassette 105?

There's no reason why you can't use an Ultegra cassette with an otherwise 105 groupset, or vice versa. With both 105 and Ultegra, the largest sprocket you can officially use is a 34-tooth, although in truth you can go much larger than that; we have gear systems with 11-40 cassettes that work very happily.

Can I put a mountain bike cassette on a road bike?

A mountain bike cassette can work on a road bike only if it has the same cog pitch as its road equivalent. If the cog pitch is different, the shifting would be inaccurate.

Is 16 gears enough on a road bike?

What is a 53/39 crankset?

Standard cranks have 53/39 gearing, meaning they have a 39-tooth small ring and a 53-tooth big ring. Ring is short for chainring, which is what the front gears are called that are bolted to the cranks. Compact cranksets are preferred for climbing races or for people who like to ride fast but not race.

What gear ratio is best for climbing?

A common setup on a road bike adapted for climbing is a compact road crankset with 50-34 chainrings and an 11-32 cassette, which gives a lowest gear of 34:32 or a ratio of 1.06:1.

How do I fit a large cassette?

Can you change cassette ratio?

From these companies you can equip yourself with a 10 speed cassette with whopping 40T or 42T largest sprocket.

How do I know if I have 10 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.

Is a 10 speed road bike good?

Yes, 10-speed bikes are good simply because they have a lot of range. 10-speed bikes are (generally speaking) an OG (i.e. one gear) which makes them far easier and cheaper to maintain. This is because you're only dealing with gears on the rear hub and you don't have to faff around with anything else.
