If you are looking for the best groupsets for your mountain bike or MTB, the Shimano Acera or Altus groupset might be the one for you.
Whether you are riding a hybrid or mountain bike, it should run smoothly and comfortably. In this guide, I will discuss Shimano Acera vs. Altus.
Shimano Altus Groupset
Shimano bikes with the right groupsets are well known among their fans because Shimano Altus groupsets can be used with mountain bikes and hybrid bikes due to the following properties. It will help you make an informed decision once you are more familiar with the Altus group’s functions.
Important parts of a Shimano Altus bike are the gear levers and the gears. The Shimano Altus group changer has an optical switch for switching and a bidirectional unlocking function to ensure compatibility with Al fine S7000-8 hubs.
As you ride your Shimano Altus bike, you will find that your brakes are more comfortable and flexible so that you can stop the bike immediately without any problems. Barking the ball becomes easier and more comfortable when using a brake wire.
The cranks used on the Shimano Altus are available in three sizes with different numbers.
It can be used for chains in 2 different sizes to ensure reliable gear shifting. This black crank makes it easy to replace the chain on the bike.
The Shimano Altus group includes a high-quality rear derailleur that makes it more durable than other groupsets. You can easily swap the rear gear for bikes with different speeds as it is compatible with 7-8 types of speed bikes.

Shimano Acera Groupset
In the Shimano MTB group area, the Shimano Acera is the middle group. Brakes and deflectors are very important between the different parts of the Acera group as they are easy to make, especially for routes. The Acera groupsets performance is gradually improving as Shimano regularly improves it every year.
The Acera MTB Groupset M360 gear bridge design is the most important part as users can use any braking level on the bike. This shifter is popular with mountain bike riders because of its low-friction design and easily accessible belt adjustment for quick set-up. The new shifter levels offer a nonslip rubber face, and Shimano says, 20% quicker engagement with less force needed to get the lever moving.
Shimano Acera usually offers disc brakes for the MTB group. However, if you need a hydraulic disc, you can find it in the Acer group too. This durable brake can stop any mountain bike’s performance while putting a fair amount of effort through its rugged system.
The Acera group of cranks has been significantly improved to make them stronger and lighter. This crank can be used with all diverters and chains. In the Acera M361 group, Shimano used three cranksets for smooth and quiet movement thanks to its hip drive system.
This is the most important part of the bicycle group. Shimano Acera deflectors are available in three-speed combinations – 3×7, 3×8, and 3×9. Acera’s front derailleurs include a swiveling model. This part does not put any pressure on your bike as it is light. You can easily adjust the cable tension by adjusting your cage.
How to Adjust Shimano Altus
Introduced in 2016, SRAM’s X01 Eagle 12-speed drivetrain offers a 500 per cent gear range through a huge 10- 50t cassette.
The Shimano Altus rear shifter is the basic shifting for mountain bikes. This switch is known for its low cost, ease of setting, reliability, and switching accuracy. However, to use the Altus key, it must be configured correctly. This means checking the cable tension and switches limits; instead of waiting for a much to work on your bike at your local bike shop, learn how to adjust Altus equipment at home.
- Hold the bike by the seat post on the bike bench so that you can rotate the bike handles freely. If you don’t have a bench, spin the bike by the handlebars and let it work.
- Loosen the Altus cable holder with a 5 mm Allen key. Twist the bike’s cranks and slide the chain to the bottom of the box.
- Check the alignment of the chain with the small gear. Determine if the chain is pulling the indexing discs on either side of the tip or the other. This setting is made with the upper stop screw, marked with an H on the wrench. If the chain is to the left of the sprocket, loosen the top stop screw until it is aligned. With the chain to the sprocket’s right, tighten the top limit screw until it is aligned.
- To make sure the gearshift lever is in the lowest gear, pull the gearshift lever down on the gearshift lever until it stops clicking. Use a pair of pliers to firmly pull the cable through the rear gear connector and tighten the connector with a 5mm Allen key.
- Squeeze the shift lever to shift the chain into top gear while manually pedaling the bike. Check the alignment of the chain and sprocket on the back of the bike. If the chain is to the left of the sprocket, tighten the lower limit screw (labeled L) with a Phillips screwdriver. If the chain extends to the right or cannot move completely in top gear, loosen the lower stop screw until it is aligned.
- Test your bike for clear and precise gear changes.
How to Adjust a Shimano Tourney Derailleur
Normal things that may occur while driving can cause the change. One good thing about this drive train is almost every mechanic knows every small detail about Tourney as they spend 90% of their time repairing Tourneys. Bumps and noises on the bike slowly loosen the fastening screws. Pressing the key yourself can disrupt the alignment. Replacing the switch yourself can save you a ride to your local bike shop and, of course, save some money. Keep in mind 90% of your derailleur’s performance is based on how well adjusted it is. The same procedure is used to set a switch.
- Stand the bike on a bench or turn it over the handlebars and seat.
- Release the link locks by turning them counterclockwise with the Allen key. The cable stop is the replacement screw through which the replacement cable is fed. Do not completely loosen these screws.
- Manually rotate the bike until the chain is in the lowest gear. When cycling, sit behind the bike and check that the gear is in the lowest gear.
- Fix as far as possible screw on the back derailleur with a screwdriver when the front derailleur pushes its chain to one side. Slacken as far as possible screw when the key pushes the chain to one side as far as the possible screw is set apart with the letter “H” on the wrench.
- Adjust the front gear screw with a screwdriver. Fix as far as possible screw when the chain slides to one side. Relax as far as possible screw when the chain slides to one side as far as the possible screw is set apart with the letter “L”.
- Set the front gear to full speed with your hands. Check the transmission alignment with the highest gear. Fix as far as possible screw on the derailleur until it contacts the chain. Release as far as possible screw until the chain is in the focal point of the sprocket.
- Fix the link locks with the Allen key. Change the bike with one gear. If your bike doesn’t move properly, tighten the tensioner on the derailleur’s back by threading the derailleur cable through it. Physically turn this handle clockwise to fix it.
How to Adjust the Rear Derailleur
When you buy bike, LBS offers 12 months of free servicing, so they will adjust all that for you. Particularly important to at least take it in for the first service free service as cables will stretch, etc.
- Move the shift lever to the top gear position, turn the pedals, and let the chain travel to the smallest cog. If there is a cable adjuster in the derailleur housing or housing, screw it in almost completely (clockwise).
- Loosen the cable retaining screw on the circuit and slide the cable aside.
- Rotate the pedals and use your other hand to slide the gear into the rear wheel manually.
- If the adjusting screw of the internal deflection is correctly adjusted, the chain only moves at the highest speed and no more.
- In case, it protrudes over the tip and falls into the spokes, turns the diverter screw (clockwise), and repeat step three. If the chain is not comfortable at the highest end, slightly loosen the adjustment screw and try again.
- When you are happy with it, let the gear spring push you into the lowest gear.
- If the chain breaks or does not fit properly in the lowest gear, turn the other adjustment screw to shift the shifting position.
- With the diverter comfortably moving between the top and bottom teeth of the box, install the diversion cable and tighten the retaining screw.
- Use the gear lever for cycling through all the gears several times. If the gear is slowly changing, unscrew the gear cable adjuster.
- If the upward movement is slow, tighten the cable adjuster. Check again that all mounting screws are properly tightened and perform a light test.
Shimano Acera vs. Altus: FAQs
Is Acera Better Than Altus?
Acera and Altus are on the same level. Altus is much better than Acera. They cause fewer problems and are more accurate. They’re lighter too.
Is Shimano Altus Better Than Alivio?
The Alivio is another little advance in the stuff progressive system, another 9-speed gearbox that offers lighter segments and preferable moving over the Acera and Altus.
Is Shimano Altus better than Tourney?
Shimano Altus and Acera are better than Shimano Tourney. They are lighter and work easier. They aren’t as advanced as relief, but they will get the job done for most drivers.
Both groups are popular with motorcyclists in their way. Both are in the entry group, which can be accessed in the Shimano group hierarchy. The differences between the two groups are evident in aspects such as their design and prices. Deore M6100 (new) SLT Deore XT XTR Tourney, Tourney TZ, and ZT Tourney is a bottom-of-the-range drivetrain model that you will most likely see on budget bikes. However, Acera is valued for withstanding the harsh conditions of aggressive driving with minimal maintenance.
The rear mechanisms of the Altus and Acera contain a Shadow RD spring. However, the Shimano Acera has a hollow shaft and is, therefore, lighter than Altus. Both groups also offer the same crank configurations.
When it comes to switches, Altus and Acera are equal to the Rapid Wire Plus technology that connects them. The option for the two group groups may not be the same, but they are the same.
