How Does A Bike Cassette Work

How does a bike cassette work. I take an old freewheel apart and show you the parts that are inside and talk about how it works. Spin the sprockets backwards. What s the difference between a standard semi compact and compact chainset. Thus a 11 28t cassette would denote a cassette with a smallest 11 tooth and largest 28 tooth sprocket.
Most mtb bikes use 9 10 11 or 12 speed cassettes although more budget models may use 8 or less commonly 7 speed. Cranks come in a number of forms for road bikes including standard compact super compact. But if it happens the day before a bike event it s nice to have. Front and rear derailleurs do all the hard work of moving the chain from one sprocket or chainring to the next.
Refers to an individual gear within the cassette block. A typical gear spread for an mtb cassette the amount of teeth on the smallest and largest sprockets would be 11 34t. If the fittings spin with the cogs it is a cassette system with a freehub. In order to remove and replace your cassette you need to unscrew this lockring.
The lockring is designed to hold the cogs of the cassette in place on the hub. If the tool fittings do not spin with the cogs it is a threaded freewheel system. Ever wondered how bike gears and gear ratios work. Cogsets come in two varieties freewheels or cassettes of which cassettes are a newer development although cassettes and freewheels perform the same function and look almost the same when installed.
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. You can have a bicycle shop mechanic do it for you because it s a quick and inexpensive repair. A typical cassette can have anything between five and 13 sprockets although most modern bicycle drivetrains use either 9 10 or 11. A chain whip a cassette lockring remover and a large adjustable crescent wrench.
The freewheel is a 6 speed shimano but they all pretty much the same. To determine if a sprocket is a freewheel or cassette system remove the rear wheel from the bike. They typically differ from road bike cassettes in having greater gaps in gearing between each sprocket. You ll need three tools to do this.
Find the tool fitting on the sprocket set.
