How do I know what size my bike cassette is?

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).

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).

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.

Are all bike cassettes the same width?

Cassette sprocket-tooth widths

Up through 9-speeds, all cassettes use very nearly the same width of sprocket teeth, and will work with 7/8 or 9-speed chains. Old Uniglide 6-speed cassettes have larger spacing between sprockets, and like older freewheels, have the same shifting issues.

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.

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.

What is a 12/25 cassette?

Most road bikes come supplied with a 12–25T cassette, where the smallest sprocket has 12 teeth and the largest sprocked has 25 teeth.

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.

What size cassette can my derailleur handle?

All derailleurs have a maximum cassette size. This is often indicated as the maximum number of teeth that can be on the biggest cog (often referred to as low sprocket max in manuals). So when you see that a derailleur has a maximum cassette size of 30T you know that the biggest cog on the cassette cannot exceed 30T.

Do all cassettes fit all hubs?

Simply put – 8, 9, 10 speed cassettes all fit on the same hub. A seven speed cassette will fit on an 8 speed freehub with the use of a spacer. (One notable exception is the Dura Ace FH-7801 hub with an alloy freehub which will only accept 10 speed Shimano cassettes – the newer Dura Ace hubs can run 8/9/10).

Can I change the cassette on my road bike?
