![]() ![]() If you’ve ever heard of ‘Junior roll-out’, this is what they are testing, as a Junior bike’s gear ratio can not be greater than a specified rolling distance. Factored in with the circumference of the bike’s wheel and tire, the gear ratio determines how far the bike will travel with one full revolution of the cranks. The combination of front and rear gear choice, typically expressed in ‘front x rear’ terms, such as ‘53×11’. “11-speed 11/28” means there are 11 rear cogs that make up the cassette, the smallest ring having 11 teeth, and the biggest having 28 teeth. Most modern road bikes have 8 to 11 gears in their rear cassette, which are again described in the number of teeth that they have on their ring, e.g. The chainrings at the hub of the rear wheel, known individually as ‘cogs’ or ‘sprockets’, and when put all together, they are called the ‘cassette.’ Pay attention, because the size of the chainring is now the opposite of the front chainring – the bigger the rear gear, the easier it is to pedal and the smaller the rear gear, the harder it is to pedal. ![]() For example “53/39” means there are two front chainrings, the bigger has 53 teeth, and the smaller 39 teeth. Most modern road bikes have two front chainrings, which are described by the number of teeth that they have. The smallest chainring in a triple-front ring set-up is affectionately known as the ‘granny gear’. Bikes have either one, two, or three front gears/chainrings, and the bigger the chainring, the harder it is to pedal the smaller the chainring, the easier it is to pedal. The rings where the cranks/pedal arms attach at the bottom bracket.

Without shifting, you could be stuck pedaling a massive gear or a tiny one, struggling on an uphill, or pedaling until your knees hurt.īike gears make cycling more accessible and enjoyable, and with a bit of customization. Next to braking, shifting is the most important thing to learn on the bike. In this article, we’ll explain bicycle gears, define terms like gear ratio, cross-chaining, and more, and teach you how to use bike gears most efficiently. You can now shift gears at the touch of a button. Shifters have come a long way in the past few decades. Gears allow us to pedal easier on the uphills, find our ideal cadence no matter the gradient, and sprint as fast as we can. Bike gears are one of the most astonishing innovations in all of cycling. ![]()
