Bicycle cassette selection
What is the function of a cassette on a bicycle?
A cassette consists of several sprockets which are fixed on a freewheel, they are driven by a chain. The cassette is one of the items used to vary the gear ratio or reduction ratio of the drivetrain so that the speed of rotation of the rear wheel varies. Lower the number of teeth of the sprocket driven by the chain, greater the speed of rotation of the wheel will be. The number of gears on a bicycle is given by the number of sprockets on the cassette multiplied by the number of chainrings.Generally a cassette is made up of 5 to 12 speeds.Lire la suite

Why the pressure of a bike tire is so important?
Tire pressure influences the grip and braking of your bike, as well as comfort of the cyclist. The pressure value therefore has an impact on your safety, your performance and the pleasure you will have in using your bicycle.
The smaller is the width of a tire, the greater its pressure value in order to avoid impacts on the rim and punctures without pinching (air chamber which is positioned between the tire and the rim, for example the pressure value for a road bike will be generally between 6 and 8 bars, while the pressure value for a MTB tire will be from 2 to 3.5 bars.Lire la suite
