The Shimano Acera range of bicycle components are specifically geared towards mountain bike enthusiasts and the range includes components such as derailleurs, shifters, cranksets, bottom brackets, brakes and brake levers.

The latest version of the Shimano Acera range is the M3000 and whilst this range is dedicated towards the more budget-friendly option for entry and mid-level riders, it retains a quality design which the rider can trust that will deliver excellent performance.

You can get the Acera in 7-9 speeds and the derailleur technology used is 9-speed Shadow. The product is lightweight and easily adjustable if any tweaks need to be made for cable tuning.

As you would expect with the range built for mountain biking, the products are built to withstand off-road bumpy ground and its performance will not be affected by rough terrain.

Crankset options: The Acera range has the option to be in 2 or 3 chainrings.

Brake compatibility: The Acera range is compatible with V-brakes, mechanical disk brakes and Hydraulic brakes.

As with the Acera range, the Shimano Deore range of bicycle components are dedicated to mountain bike enthusiasts, but where there is a difference between the two ranges is the price. So, what exactly sets the two apart and is it worth the average paying more for the Deore range?

You can get the Deore in 10-12 speeds and the derailleur technology used here is the 12-speed Shadow Plus.

Crankset options: The Deore range has the option to be in 1 or 2 chainrings.

Brake compatibility: The Deore range is compatible Hydraulic disk brakes.

As this is a higher end suite of products the performance is better than the cheaper Acera range. The additional gearing options make the tough climbs and fast descents easier.

The braking options offered under this groupset are brilliant and will provide the rider with increased confidence when flying down fast trails, and the increased stopping power will also come in very handy in adverse weather conditions.

Key comparisons


The Deore range is lighter than the Acera range, and whilst there isn’t a lot of difference between the two groupsets, but every little bit helps especially on hilly routes where additional weight can significant.

For those looking to make weight savings which will contribute towards performance improvements the Deore range would be the more suitable choice.


We have already mentioned that the Deore range is more expensive than the Acera range – there is about a £100 price different between the two groupsets depending on the retailer.


The Acera groupset only offers 9-speeds against the 12-speed option of the Deore. This is where the decisions need to be made based on the kind of riding you’re doing, but for me living in a very hilly part of the world I’d be inclined to go for the 12-speed option to help me tackle big climbs and fast descents.

The brakes offered in the Deore range are slightly more advanced than the Acera range, however, there isn’t a massively noticeable difference for the average rider who isn’t after top performance.

Key Questions Answered 

1Is there a difference in the number of gears offered between the Acera and Deore?
Yes, there is, which may impact your choice. The Acera typically offers 9-speed and the Deore is available in 10 or 11 speeds.
2Are the Acera and Deore ranges made out of different materials?
 Yes, the Deore range of components are made from higher quality materials and will therefore be more durable and long-lasting.
3What level of rider does either range suit?
The Acera is primarily aimed at the entry level rider and the Deore is more of a mid-level product. The Deore offers more speed options and you will get a more durable set of components but this comes at a higher price.

Are there any pros and cons to either range?

Conclusion and Recommendations

Both the Acera and Deore ranges are excellent choices for those who are looking to upgrade their mountain bike components to a stable product that will deliver consistent performance time and time again.

The durability of the Deore range is definitely an advantage, especially for those who are taking the bike out numerous times per week, and initially spending a bit more will more than likely pay dividends over a longer period of time.

Another positive aspect of the Deore range is the fact that it offers a choice of 12-speeds which will help a lot on climbs and descents – living in a very hilly part of the world this would be my go-to choice if I was looking at new component parts.

Both ranges of products are excellent choices and you would not be disappointed with either and both will serve the rider well.

It is also largely dependent on personal circumstances such as where you ride and your available budget, but if I was going to choose a new component set for my mountain bike, I would go for the Deore range.
