Which One Is Better?

The Shimano Deore and Acera are perfect groupsets for mountain bikes. If you don’t want to buy additional gear for your bike, check out our best mountain bikes review since they’re fully equipped and also they are both strong, and can serve you for some time without needing replacement. They also allow you to change gears quickly.

Nevertheless, the Acera models are not as strong as the Deore counterparts. They cannot handle rough terrain, meaning you can only use them for recreational purposes. Therefore, the Deore groupsets would be your best option if you like cycling in rough terrain.

Though they are strong, they’re quite expensive. If you’re on a tight budget, your best pick would be the Acera groupsets.

Dual control levers (mechanical)

Dual control levers refer to levers that feature shifting and braking capabilities for easy bike operation. They allow you to shift and brake your bike without removing your hands from the handlebars.

All Shimano groupset models, including Shimano Deore and Shimano Acera, have dual control levers. The good thing about these units is that they have an ergonomic design that makes handling your bike easy.

It’s important to note that the thumb levers on the Shimano Dual control levers are detachable. Therefore, you can leave them attached and shift with them or take them off and only use the main levers. In our opinion, the latter is quite simple when you practice regularly.

Dual pivot brakes

Dual pivot brakes are brakes whose caliper arms swing on different pivots, making the pads move in different arcs as they approach the rim.

Typically, they are attached using a single bolt in the fork crown and brake bridge, but they feature a yoke that connects to this and separates the pivot points for the arms. The dual pivot brakes offer higher mechanical advantages and are easy to center.

Shimano bike groupsets like the Deore and Acera models feature dual-pivot brakes. Over time, the company has adjusted the brakes to ensure they perform better. They’ve become lightweight, compact, and strong. If you’re looking for a groupset with strong dual-pivot brakes, consider the SHIMANO ALTUS ACERA 3×7 Speed Groupset. Moreover, they’ve managed to provide a firm, immediate braking response while guaranteeing a longer lifespan.

Disc brakes

Bike disc brakes feature a metal rotor resembling a disc that spins inside a wheel to act as a brake. When you apply pressure on the pedal, the caliper squeezes the brake pads against the disc, creating friction that enables your bike to stop or slow movement.

Shimano bike groupsets feature hydraulic disc brakes, which aid in controlling the movement of your bike when cycling. This way, you can easily prevent accidents, especially when riding your bike on rough terrain.

One of the best things about disc brakes is their better modulation, allowing the rider to gauge the clamping power produced. Peak stopping force occurs just before lock-up, and bikes with disc brakes and motorcycles with disc brakes can better lean on the safe side without tipping over.

A chainset is a component that helps connect your bike’s chain to the cassette at the back. Typically, chainsets vary depending on the groupset.

The Deore groupsets feature chainsets that are compatible with speeds of 9, 10, 11, and 12. On the other hand, the chainsets included in the Acera models operate with speeds of 7, 8, and 9.

One of the good things about the Shimano Acera chainsets is that they’re lightweight and durable. Additionally, they feature chainrings that offer silent and trouble-free shifting.

Front Derailleur

A front derailleur Trusted Source The Derailleurs - How Mountain Bikes Work | HowStuffWorks The derailleur is the device that changes gears by moving the chain from one sprocket to another. There are two derailleurs: one on the rear and one on the front. is a device that moves your bike’s chain from one chainring to another. Different groupset brands offer different front derailleur designs. Nevertheless, they use a similar principle to operate. When you press the front shift lever, it usually moves from side to side, carrying the chain along with it.

Shimano Deore front derailleurs work with speeds of 9, 10, 11, and 12, while their Acera counterparts are compatible with 7,8, and 9-speed drive trains.

Front derailleurs from both groupset models have their advantages. Those included in the Acera groupset are easily and readily compatible with most bike frames thanks to their top swing design. Conversely, Shimano Deore front derailleurs are lightweight, have better-shifting performance, and can mount neatly on rigid frames with a bigger bottom bracket.

Rear Derailleur

Rear derailleurs adjust the chain at the back sprockets. Although there are many different rear derailleur versions, they all have the same basic functionality and appearance.

Just like the front derailleurs, Shimano Deore rear derailleurs are compatible with speeds of 9, 10, 11, and 12, whereas the Acera counterparts work perfectly with 7,8, and 9-speed drive trains.

Shimano Deore derailleurs have less tension in the low gear position, allowing for excellent shifting performance even over rough terrain. The Acera model front derailleurs also have their advantages. One of the main advantages is that they’re compatible with many  mountain bikes Trusted Source Some of the Advantages of Using Mountain Bikes With so much comfort, safety and range mountain bikes are the best thing to have for a ride. So why would you want to buy anything else! . Moreover, they feature a double servo construction for accurate shifting

A cassette is a group of gears or sprockets in the rear part of your bike’s wheel. Cassettes normally come with different speeds and sizes. Typically, the type you buy depends on the bike’s price and riding style.

Shimano Acera designs cassettes with a Hyperglide technology that enhances shifting. It also features a tooth profiling and nickel finish for proper cleaning. Shimano Deore cassettes also feature tooth profiling and are compatible with 9, 10, 11, and 12-speed drive terrains.


Your bicycle’s chain plays a major role when it comes to making movements. It transmits the force from your pedals to the wheels, enabling you to move from one point to another.

Shimano Deore groupsets come with HG chains and are compatible with 9 to 12-speed configurations. Similarly, the Acera model features HG chains for easy and quick shifting. The only difference is that the latter is compatible with 7,8, and 9-speed configurations.

Bottom bracket

The bottom bracket is one of the essential components in your bike’s groupset. It connects the crankset of your bicycle to the frame, enabling it to rotate independently.

Bottom brackets come with different designs depending on the groupset model. Generally, the Shimano groupsets have HollowTech II bottom bracket designs. Nevertheless, they have different dimensions.

The good thing about Shimano groupset bottom brackets is that they’re quite easy to install and serve you long. Moreover, they’re efficient at transferring power.


Different groupsets models have different weights. Lighter groupset components are advantageous since they’re easy to handle. Generally, Shimano Deore components are lighter than those of Acera. If you’re looking for a bike groupset with light components, consider the Shimano Deore M5100 Groupset 11.


Price is one of the main factors you should consider when buying bike groupsets. If you’re on a limited budget, consider settling for cheaper groupsets. The only disadvantage is that the cheap ones are of poor quality. They wear out quickly, forcing you to replace them regularly. This means you’ll spend a lot of money in the long run.

Generally, Shimano Doere groupsets are quite expensive compared to Shimano Acera.
