Can I change front derailleur?

Do all derailleurs fit all bikes?

A derailleur for your mountain bike should match the specifications on the original derailleur. That is, while it doesn't need to be the same model of derailleur, it does need to be the same brand, in almost every case. It also needs to match the number of gears, or have more intended.

Can you use a bike without a front derailleur?

These days front derailleurs are essentially not necessary, on mountain bikes at least. With a larger rear cassette, it's possible to get the same number of gears without the need for a front derailleur. Therefore the arguments that a lack of derailleur means less range are no longer valid.

Are front derailleurs universal?

In addition, front derailleurs are made for either 7, 8, 9 or 10-speed chains, but they can often be used interchangeably. If you are using a different chain than your derailleur was made to work with, the degree of adjustment you can expect will be lower than with a matched set.


How do you fix a Shimano derailleur?


Which derailleur do you adjust first?

In a nutshell, adjust the front derailleur first, then the rear. If the derailers just need minor tweaking (they are basically in adjustment but are "not quite right") then you adjust the one that is obviously wrong, check the overall adjustment again, then again adjust what needs adjusting.


Which Shimano derailleurs have a clutch?

Clutch derailleurs explained

Almost all modern mountain bike derailleurs (and Shimano's GRX gravel groupsets, Ultegra RX rear mech, SRAM's single-ring road groupsets and eTap AXS 12-speed road rear mechs) include a clutch mechanism.


Do I need a short or medium cage derailleur?

It's generally best to go for as short a derailleur cage as you can get away with, as long as you can avoid the chain contorting on the extremes of the cassette, such as using the largest on both sprocket and chainring. Smaller cages tend to have snappier gear changes, they're lighter, and also less exposed to damage.


Can I use any shifter with Shimano derailleur?

Shimano shifters, whether for 6, 7, 8, or 9 speeds are compatible with all the Shimano RDs for 6 to 9 speeds, and with Shimano 10 speed road RDs (not with 10 speed MTB RDs). Update: a new exception are Shimano Tiagra 4700 road 10-speed shifters, and Shimano GRX gravel series shifters.


How do I find the model number of my Shimano derailleur?

Shimano stamps the rear derailleur model number on the underside/lower plate of the parallelogram.


Is my derailleur SS or GS?

It's easy to remember that SS (short cage) is for cross-ratio road sprockets and GS (medium cage) is for wide-ratio sprockets, but just because the maximum number of teeth is large doesn't mean that GS (medium cage) is the best choice.


What is the difference between a medium and long cage derailleur?

If you are in-between the capacity ranges of the two, which is often the case with mountain bikes, then note the following: long cage derailleurs will accommodate a wider gear range and deliver a better chain line, while medium cage derailleurs are less likely to be hit by rocks on the trail.


Should I take off my front derailleur?

Removing the front derailleur isn't really a good idea, gear wise unless you have a good reason to. All you're doing is taking away the little mechanism that moves the chain from one front ring to another. If you're not happy with the shifting, get it tuned, not remove it.


What is the purpose of front derailleur on a bike?

The front derailleur is the mechanism that shifts the chain on bike with more than one front chainring. There are many different makes and models, but they all share the same basic design and functionality. Front derailleurs are attached to the bike with either a clamp or bracket.


Are front derailleurs obsolete?

SRAM are announcing the end of the front derailleur in mountain biking. The 1x drivetrains on offer from several manufacturers coupled with the range of gears on offer from an 11 speed cassette have rendered the front mech obsolete.


How much does it cost to replace a derailleur hanger?

How Much Does A Derailleur Hanger Replacement Cost? It's possible to get a decent derailleur hanger for $10-$20. Only a handful cost more than $20. Derailleur hangers are cheap because they are generally designed to break or bend in place of your drivetrain or bike frame.


When should I replace my derailleur?

Derailleurs will last almost indefinitely. The jockey wheels will wear out in time (tens of thousands of km) but the rest of the mechanism shouldn't see significant wear. It could be that the spring will break at some point due to material fatigue, but that is also a relatively easy to replace part on most derailleurs.


How do you fit a front derailleur?


Should my derailleur be straight?

unless you have it on the grannie up front (or the cranks are way off the proper chain line) it should be reasonably straight line. It's very unlikely that you bent the parallels on the actual derailleur, possible, but very unlikely..

How do you straighten a derailleur hanger without tools?


Do derailleur springs wear out?

That said, derailleur springs will lose tension overtime, and pivots will get sloppier. Shifters can wear out too (if you ride enough), and most cannot be serviced back to health. But before you go sinking money into these more expensive components, best try a new cable/housing or get a second opinion.


Where should front derailleur be placed?

The front derailleur cage should be approximately parallel to the chain. If the derailleur cage is rotated too far from this position, it will shift poorly. If the derailleur mount is a clamp type, its rotation can be changed. Generally, the outer cage of the front derailleur should be aligned to the chain.


How tight should front derailleur cable be?

You need to pull it pretty tight before clamping it to the derailleur. Probably as tight as you can. Usually I find that's still not tight enough, so I screw the barrel adjuster down all the way before putting the cable in and then open it up until the tension is correct.

Can I use MTB front derailleur on road bike?

The spacing between chainrings, double, triple, 8-,9-,10-speed (the thickness of the rings are different) are basically the same. A road FD and a road shifter will work fine. A mt FD and mt shifter will work fine. A road FD and a mt shifter will not work well.


Can I use a double front derailleur on a triple?

Yes you can, as long as you use a mountain front derailleur. If you were to use a road double front derailleur, the throw would be different and it wouldn't work. In other words, shorten the cable so the derailleur moves immediately from the smaller chainring when you push the lever.
