How to choose your road bike cassette?

Made up of all the sprockets, the cassette is essentially the gearbox of your bike. It is important to choose this component carefully so that it is not only compatible with your rear wheel and the rest of your drivetrain, but also to select gear ratios that suit you based on your riding terrain. Here is some guidance on the subject.

Standards

  • The number of speeds, currently: 9, 10 or 11
  • The freehub body type: CAMPAGNOLO or SHIMANO / SRAM
  • The drivetrain brand: CAMPAGNOLO or other
  • Sprocket ranges

Types of cassettes

First of all, it is useful to clearly differentiate between the cassette type and the freewheel type. When the sprockets are screwed onto the freehub body, the assembly is called a "freewheel" — this standard is fairly old a. When the sprockets are independent of the freehub system (called the freehub body), the set of sprockets is then called a "cassette" — this is the current standard today b.

All the components of a drivetrain are designed to work under a specific speed standard, so you cannot pair a 9-speed road cassette cassette with a 10-speed drivetrain, for example. Today most road bikes are 10 or 11-speed, although 9-speed can still be found.

The freehub body of a wheel is the part that acts as the support for the cassette. There are two standards: the one imposed by Shimano (also used by Sram) a compatible with 9, 10 or 11-speed cassettes, and the one developed by Campagnolo, only compatible with that brand b.

Cassette sprocket counts are always described by their extremes. For example, if it states "11/28", the smallest sprocket will have 11 teeth and the largest 28. The more teeth a sprocket has, the less effort is required to turn the wheel: ideal for long climbs.

Which cassette should you choose?

Cassette choice will depend above all on the rest of your road transmission; you will therefore need to choose the same speed standard as what you already have. In the case of a Campagnolo drivetrain, make sure you choose a cassette from the same brand or compatible with it.

Depending on the capacity of your derailleur, you will be able to choose the sprocket range based on your riding terrain and your level.
