What to look for when buying a derailleur?

Now, here comes the buying guide. Many mountain bike riders don’t know how they can choose the best front derailleur because selecting the best one is very tough. If you choose the wrong one, your money and attempts will go to the dogs. That’s why we are here with a good buying guide. Let’s begin.

Braze-on VS clamp-on

The word “Braze-on” refers to a part of a bike. We attach it to the frame of a bike either by welding, bolted, or glued. We can call it is a permanently attachable bike material. On the other hand, a clamp-on means a non-built bike part. If your bike takes a braze-on front derailleur, it indicates that it must have a bracket on the bike frame. Certainly, the braze-on front derailleur has some advantages. Moreover, a clamp-on product also takes some pros.

Though both of them are quite well, most bikers prefer to have the braze-on front derailleur. So, choose one of them which you prefer most.

Cable Pull Direction

Indeed, it means a front derailleur that works using the cable direction. Above all, there are two types of cable pull. For example, they are top-pull and bottom-pull. Besides, some derailleur works both ways, and we know it as a dual-pull product. If you activate it with your hand, you will know the derailleur, top-pull, bottom-pull, or dual-pull.

So, you have to ensure that the front derailleur works with the position of the cable stops or routing on your frame.

Chain catcher

Especially to prevent the chain from dropping from the chainring. It is an add-on material that surely helps to protect your ride from chain dropping.

Compact chainsets

To sum up, compact chainsets are an alternative to a triple chainset. Because they give you a good wide ratio of gearing, also, they ensure a good chain line and give increased chain strength.

Moreover, the compact chainsets also have a bigger and rear plate to cope with the large difference in chainring sizes, especially 34-50.


Firstly, a front derailleur functions with double or triple-chainring sets. In other words, a broad derailleur works with a triple, and the narrow one works with double chainring sets. As a result, designers have made a derailleur for 7, 8, 9, or 10-speed chains. But you can use it interchangeably.

So, you have to select the derailleur that matches your bike.

Derailleur types

First of all, you need a front derailleur with double or triple cages. But be careful! Because you have to select one which matches with your bike. As a mid-level biker, we would like to suggest you have a 9-speed drivetrain.

Moreover, the cable pulling system also affects a front derailleur. This is because if your derailleur and cable pull don’t match, you have to face problems. So, have a clear thought about the cable pull before buying a front derailleur.

Number of Gears

At present, modern chains are getting narrower to accommodate more cassettes sprockets. And the front mechs are also changing their width slightly. So, you just need a front mech that matches with the chains and the number of gears. Meanwhile, for better works, there are 9, 10, or 11 speeds.
