About Cassettes & 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.

Product Q & A
Ask your questions and share your answers.
Which is the best ratio for using on a road bike that will be used mainly for triathlons.
For instance, on a flat course that may have some rolling bits where you need to change down you might want to opt for a close block ratio like 12-21. You could maintain a consistent cadence over the lumpy bits and carry it well onto the flats and descents without having large jumps of 2-3 teeth in the gears. However on a hilly course you might want something bigger like a 26 on the back to spin up the climbs. Don't get too hung up on gears. On my 8 speed training bike which I have raced on I run a 12-26. I find this gives me a lot of options.
If you want to see huge improvements on the bike get a mate to help with a bike fit and buy some clip on aerobars.
