What is a cassette on a road bike?
The cassette on your bicycle can be found on the rear wheel and is a cluster of sprockets that are a part of the drivetrain. They slide onto the freehub, the ratchet system that controls the drive of your bicycle when you pedal, and can have anything from 5 to 12 ‘speeds’.
What does a bike cassette attach to?
rear hub
A bicycle cassette is the cluster of sprockets located on the rear hub of your bike, slotting onto a freehub body and held firmly in place with a threaded cassette lockring. A typical cassette can have anything between five and 13 sprockets, although most modern bicycle drivetrains use either 9, 10 or 11.
What are the rings on a bike cassette called?
Typically the chainrings are identified by mentioning their position (“inner”, “outer”, or, in the case of a triple “middle”), or by their size “big ring”, “little ring”.

What does the cassette sit on?
The cassette is the gear mechanism on a geared cycle. It is located at the centre of the rear wheel and consists of a group or cluster of chromium-molybdenum steel sprockets or cog wheels.
What is the difference between cassette and thread type?
Find the tool fitting on the sprocket set. Spin the sprockets backwards. If the fittings spin with the cogs, it is a cassette system with a freehub. If the tool fittings do not spin with the cogs, it is a threaded freewheel system.
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.
Can I put a 7 speed cassette on a 11 speed hub?
Condensed answer: A 7-speed cassette can be installed on an 11-speed hub. Since 7-speed cassettes are narrower than 11-speed cassettes, the installation will require the use of a spacer to make up for the gap left on the hub.
What is a cassette on a bike?
Those sprockets – or gear wheels, if you prefer – are your cassette. Cassettes come in a wide range of sizes to suit all disciplines. The size of a cassette is usually expressed by quoting its smallest and largest cogs. As an example, a typical modern road bike cassette may be an 11-32t (teeth) cassette.
How many sprockets are in a cassette?
A cassette might have anything from 7 up to 13 sprockets. These days, it is increasingly common to see higher-spec road bikes with 12-speed gearing, Shimano having joined SRAM and Campagnolo with 12-speed groupsets in 2021 with the release of its Dura-Ace R9200 groupset.
How many gears are there in a cassette?
There can be anywhere from 5 to 12 gears in back on a cassette. Coaster brake the type of bike brake that slows you down when you backpedal Chain: a system of interlinking pins, plates and rollers that transmits power from the front chainring to the rear gears or cassette and turns the rear wheel
What are the parts of a bike wheel?
Each wheel is made up of several other bike parts though… The hub is in the centre of the bike wheel. It’s made up of 3 parts: the hub shell, the bearings and the axle. The hub shell is the exterior part that the spokes attach to. The axle is the bar that protrudes on either side, and that attaches to the frame.
