自分のニーズに合わせて適切なMTBグループセットを選ぶには

Mountain bikers have always had their own language. From the early days of the sport in Southern California, to the globe-travelling circus that is modern World Cup racing, the sport and its riders have always talked with a unique mix of action sports slang and engineering terms.  

Coming into the sport, this can be a little intimidating. Do you shred? Are you stoked? And why on earth do you need a groupset so much? We can’t help you with the first two questions, but we do know a thing or two about mountain bike groupsets. This short guide breaks down what a mountain bike groupset is, the differences between different levels and brands, and which one is right for you and your budget. 

A bike groupset is a collection of components that form the transmission or drivetrain for your mountain bike. It is the system that uses the power from your legs to turn the rear wheel.  

A mountain bike groupset is made up of: 

Cranks - these are the arms that you turn with the pedals to move the bike forwards. They may also be referred to as a crankset. Higher end cranks tend to be made from carbon fibre to reduce weight. 

Chainring - attached to the cranks is a chainring. This is essentially a cog with a special pattern of teeth to help keep the chain in line. The size of the chainring determines your gearing (how hard or easy the bike is to pedal), a bigger chainring will be harder to turn, while a smaller one will be easier. 

Derailleur - working with the shifter, the derailleur moves the chain up and down the cassette to change through the gears. Mounted just ahead of the rear wheel it is the heart of your drivetrain. 

Shifter - the shifter is mounted on the handlebar and controls the derailleur to select which gear you which to use.  

Cassette - a collection of sprockets or cogs attached to the rear wheel, the cassette is the other half of your gearing. While at the crank a big chainring means a big gear, at the cassette it is the opposite: a big sprocket means an easy gear and a small sprocket a hard gear. High-end cassettes are manufactured and machined much more extensively than their lower end equivalents, so this is one area where you can make a significant weight saving by going up through the levels.  

Chain - engineers refer to the style of chain on a mountain bike as a roller chain, but we generally just call it a chain. It connects the crank to the cassette and the derailleur, transferring the power from the rider to the rear wheel. 

Bottom bracket - the bottom bracket houses the bearings that allow your crank to spin smoothly. It is separate to the crank because the bearings have a limited lifespan and will need replacing throughout the lifetime of the bike. 

You may see some people include brakes in groupsets. We don’t include them because for some of the bikes we make we prefer to offer brakes by a different brand to the one supplying the drivetrain – for example, on our mullet mountain bike, the Torque 5). Generally brakes are not considered a part of the groupset because they are not part of the transmission of the bicycle. You may see that some of our models feature a drivetrain from one manufacturer and brakes from another, so we think it is simpler to not include brakes. 

While it may seem logical to include pedals in a groupset, this has never been the case. The word groupset is originally a bike industry term to describe a group of components to be sold together, often to a manufacturer rather than consumers. Pedals are matter of individual preference and different riders prefer different types of pedals, which makes it too complicated for a bike manufacturer to cater to all these tastes. The solution has always been to not include pedals in groupsets so customers can buy their preferred pedals later. 

If you own an older mountain bike, or are coming from road cycling, you might expect a bike with multiple chainrings, but today we only sell mountain bikes with a single front chain ring. These are often referred to as 1x drivetrains. There are many reasons why this is so. First amongst them is that with modern wide-range (huge) cassettes on mountain bikes you have a bigger range of gears than you would have in the past, even with three chainrings. This means your easier gears are easier and your harder gears are harder.  

By simplifying the drivetrain, maunfacturers are able to add a clutch to the derailleur to help you avoid dropping a chain. This small device in the knuckle of the derailleur prevents the cage swinging backwards and forwards violently, which helps keen the chain running smoothly on rough terrain. Simplicity also helps riders new to the sport. With a single shifter to think about, it makes shifting gears much easier and more intuitive.  

Manufacturers offer different levels of groupsets. A low-end mountain bike groupset will typically be more affordable, but heavier and with fewer features than a high-end groupset. That said, across the market today the overall standard is very high, so even if you choose a basic groupset, you can be confident it will do the job of keeping your bike moving really well. The question is how far can your budget stretch and how important fare features and weight for you.

In recent years, electronic shifting has become more popular with mountain bikers. It is advanced, lightning fast and exciting. It is also quite expensive. How those two factors balance will depend on your budget and preferences. Some people like the feel of mechanical shifting on their mountain bikes, some people don’t want electronics on their bikes, and some people have a budget to stick to. If this sounds like you, then don’t worry, you can still have just as much fun out on the trail with a mechanical groupset.

For optimum performance it is best to stick with a drivetrain from a single manufacturer. They work hard to make sure all the components work together, so you can be confident of having a great ride.  

Within a brand you can usually switch between different levels - for example a Shimano XTR shifter will work with a Deore derailleur, and a SRAM XX1 cassette will work with an SX chain. The exception to this is Shimano Cues. Because this groupset only has ten speeds, you cannot run the shifter, derailleur, chain and cassette with any other Shimano groupset because it requires a different thickness of chain and a different ratio between the shifter and derailleur.  

Should you need to, you can switch some components between brands. For instance, it is not uncommon to run a third-party crank and chainring with both SRAM and Shimano drivetrains. The parts that need to be kept together are the shifter and derailleur, and the crank, bottom bracket and chainring. This means you cannot run a SRAM shifter with a Shimano derailleur, or a Shimano crank with a SRAM bottom bracket (Check out our comparison guide on the latest 1x12 MTB groupsets from Shimano and SRAM). 

The most honest answer is that you can have a great ride with any of the groupsets we build our bikes with. If you are the kind of rider that prioritises climbing, then it may be worth investing in the lightest (highest level) groupset you can afford as the small differences between each component at each level can add up to a significant weight difference overall.  

Are long miles your thing? It might be worth going up a level or two as usually the higher end components last better, although the differences are nowhere near as big as they used to be.  

If you are the kind of rider that likes to just get out and ride, then we’d say don’t worry about which groupset you have, you’re going to have a great ride on whatever your budget can afford.
