![]() If you have just one chainring, then you have a 1x drivetrain. This determines the kind of drivetrain you have. The chainring is the disc that is directly connected to your right crank arm. In the case of 7-speed bikes, high gear is when your chain is on the smaller cogs, while a low gear is when it is on the larger cogs. Note that upshifting is the term used when you are moving from low gear to high gear. This is where you need to exert a lot of effort to move your bike. This is used mostly when you are descending downhills and sprinting on flat section trails or pavements.īeing on a high gear setting means that your chain is running on the largest chainring and the smallest cog on your cassette. On the other hand, the high gear is the speed setup that you’ll use when you’re in high-speed situations. You then downshift if you move from high gear to low gear. That’s where low bicycle gears come in because they are built for low-speed scenarios such as climbing cross-country uphills.Ī low gear setting means that your chain is on the small chainring and a large cog on the cassette. Think about biking towards the top of a hill and exerting a lot of effort.Ĭhances are, is that you can climb it and you’ll just stall. This is useful when it comes to climbing. ![]() Low gear is also called easy gear because you don’t need to exert a lot of effort to push the pedal with your foot and to move. Low Gears vs High GearsĮvery mountain biker needs to know that there is a low gear and a high gear. Having more gears just complicates the gear range and mechanism for shifting gears from the easiest gear. So, how many gears do downhill bikes have to shift gears efficiently?ĭownhill bikes also have 7-speed drivetrain setups because of their convenience for high-speed descents and safety in avoiding loose chains. Meanwhile, a 7-speed bike is usually used for dirt jumps or trials because you don’t need to change speeds when you’re in these mountain biking disciplines. The most common ones you’ll find these days are 21-speed and 24-speed bikes as they can be used both on roads by road bikes and on trails even by hybrid style bikes. If you have a 2x drivetrain along with 8 cogs or sprockets, then you have a 16-speed bike. Gears work by simply multiplying the number of sprockets found on your rear drivetrain and the number of chainrings you have beside your crank arms. This covers the shifters, front derailleur, rear gears derailleurs, cranks, chain, and cogs. The drivetrain is a collective term of all the components that make up your bike’s engine. They are also referred to as the letter “t”. Teeth are the small spikes that protrude on the sides of a chainring and cog. An example of this is 11-28, which means that you are running on an 11-teeth chainring and a 28-teeth sprocket or cog. The ratio is the relationship between a chainring and a sprocket. Their number of teeth also varies from each other. Each sprocket has its own size, which is different from its other counterparts. SprocketĪ sprocket is also known as a cog, which is among the many cogs located in the cassette. Meanwhile, premium bikes that have 1x drivetrains only have a rear-wheel derailleur. Most budget bikes have a front derailleur and rear derailleur. In simpler words, it moves your chain to another cog so you can gain the required speed and amount of effort needed to go past trails. Derailleursĭerailleurs are the technical component of a drivetrain that is responsible for shifting your gears. ![]() The top-of-the-line bikes have 12 gears in total. However, there are higher-end models that have more cogs. It usually has 7 cogs in it, which means that it is a 7-speed bike. This contains multiple cogs or gears ranging in different sizes. CassetteĪ cassette is a group of sprockets or cogs found at the back section of your drivetrain. It is also attached directly to your right crank, just on the side of your right foot. This can be found on the front section of your drivetrain. The chainring is a ring that has multiple teeth on its sides. The first term you should know is the chainring. Important Terminologies to Know Chainring It’s all a matter of knowing your required speed so you can choose the right gear. On the other hand, you can shift to the smallest cog if you want to go as fast as possible when riding downhills or flat section trails and paved roads. Shift to the biggest cog if you want to have more power when climbing uphills. The cogs also vary in size, ranging from the biggest to the smallest. This serves as the speed option for the rider. Although this depends on the number of chainrings a bike has, a 7-speed bike usually means that there are 7 cogs found at its rear. A 7-speed bike is a kind of bicycle that has a drivetrain with 7 gear speeds.
