About
Cassettes And Freewheels
Cassettes and freewheels for bikes are a cluster of sprockets in a
range of sizes offering a multitude of gear ratios. The difference
between the two is, a cassette slots onto the freehub, which has the
ratchet built in and is then secured with a lockring, whereas a
freewheel is a cluster of sprockets built around a ratchet and threads
directly on to the hub. Cassettes and freewheels come in many ratios,
close ratio is when the number of teeth increase in small increments of 1
or 2 at a time, whereas a wide ratio is when the teeth increase in
larger increments of 3 or 4 at a time. Most systems will use a cassette
hub as these allow for a wider bearing spacing and increased axle life,
you can also fit a larger quantity of sprockets onto a cassette hub with
11 speed systems now becoming available. With cassettes you must use
the appropriate spacing for your gear levers and rear mech, Shimano and
Campagnolo are not interchangeable so you will need to match the
cassette to your levers for smooth and precise shifting. Sram and
Shimano chains and cassettes will work together as they use the same
spacing.
