Are rear derailleurs hard to replace?
Believe it or not, it’s not difficult to replace the rear derailleur yourself. Before replacing a “bent derailleur” make sure it’s not just the derailleur hanger! First, remove the idler pulley — that’s the bottom pulley of the derailleur.
Can you mix and match derailleurs?
As a general rule of thumb, it’s best not to mix and match drivetrain components from different brands. While things such as cranks, chains and cassettes are mostly inter-compatible between brands, generally speaking, shifters and derailleurs aren’t.
How much does it cost to replace a rear derailleur?
If you take your MTB into a local bike shop the average price to replace a rear derailleur is going to be $110. If you DIY replacing a derailleur will cost about $50 (plus your time) This price will depend a lot on the actual derailleur needed. Usually a bike shop will also take care of other problems.
Are rear derailleurs universal?
No, bike derailleurs are not universal. A derailleur that works with one bike may not work with another bike based on factors such as the cage length. Check the difference between the smallest and largest cogs and also the chainring size to determine the derailleur compatibility.
How do I know if my rear derailleur is worn out?
All derailleurs wear out at some point. Check for wear by pulling laterally on the lower cage. Compare this movement in the linkage of a new derailleur. Sloppy pivot and linkages will produce inconsistent shifting, and the only solution is a new derailleur.
Can you replace a derailleur without breaking chain?
If the derailleur is riveted closed, you won’t be able to take it off the bike without breaking the chain or destroying the derailleur. If you’re going to replace it, then you’ll need to break the chain anyway to put the new derailleur on. So if that’s the case, then just buy a chain tool and new derailleur.
How long does a rear derailleur last?
Good quality rear derailleur can last between 3 to 5 years, when unbranded or low-quality ones can last for 2 years, no matter what the durability of the rear derailleur the jockey wheel will wear after time and it can be replaced very cheaply with new ones, on the other hand, front derailleur can last almost
What is the difference between short cage and long cage derailleur?

Can you use any shifter with any derailleur?
No, different maker or different model with different number of “speed” shifters have different pull ratio (i.e. the length of cable pulled by a single shift). Usually it’s safe to use different model with same number of gears from the same maker.
When should I replace my bike 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.

Why does my bike chain slip when I pedal hard?
These include worn out or misaligned derailleur pulleys, old or malfunctioning shifters throwing off the indexing in some gears, or broken/bent teeth on one or more cassette cogs. Build up of dirt and grime on drivetrain components will also cause shifting issues, including skipping chains.
