Asked by: Samantha Campbell
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.
How often should you replace your derailleur?
Once the chain wears “or stretches”, it starts wearing the cogs and you pretty much need to replace both to get shifting working again. If it’s been 6 months and you’ve been riding much at all, you should have replaced the chain at least once.
How do I know what derailleur I need?
If you are replacing an existing derailleur on a bike, simply count the number of cogs on your cassette and you’re good to go. If your drivetrain’s speed is an unknown quantity, you can count the number of steps that your shifter runs through and add ‘one’ to determine the number of gears your drivetrain has.
How do I know if I need a new rear derailleur?
If there’s play, get a new one. Also, drip some Tri-Flow or something into all the pivots. If it’s really dirty and sticky, it’ll have a harder time with the shift you describe. If with clean, lubricated pivots the derailleur still won’t move well, you probably need a new one.
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
How much should a rear derailleur cost?

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.
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.
What does total capacity mean for rear derailleur?

Can you use any derailleur?
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.
