In terms of compatibility, with other brands (Shimano and SRAM) using a different speed count shifter than derailleur (8 speed shifter with a 9 speed RD, or vice-versa, for example)
works fine, as long as the RD pull ratio is the same and matches the shifter’s “original” (intended matching) RD pull ratio
.
Will any shifter work 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.
How do I upgrade my bike derailleur?
Why is my derailleur clicking?
If you hear a constant clicking (especially in certain gears), it could mean that
your shifter cables have stretched enough to pull your derailleur out of alignment
, causing your chain to ride between gears or rub on the derailleur cage. First, make sure your derailleur is aligned and that the hanger isn’t bent.
How much does it cost to replace a rear derailleur?

Does derailleur need to match cassette?
The rear derailleur must be matched to the size of the largest rear sprocket
. This capacity, which is expressed in terms of teeth, accounts for both the difference in size between both chainrings (e.g. 14T for a 53/39T crankset) and the largest and smallest sprockets on the bike (e.g. 17T for an 11-28T cassette).
How do I know what derailleur I need?
Can you mix Shimano groupsets?
It is possible to mix and match as long as you get components from the same generation
. For example: 9000 Dura Ace, 6800 Ultegra, and 5800 105 are all cross compatible. Each have 11-speeds in the rear, use the same cable pull per shift and use the same front derailleur design.
Does a rear derailleur make a difference?
It is more about the package not just difference in a single part.
The higher end parts are going to perform somewhat better
. How much really depends on the person and how they are going to use it. If you are going to only ride your bike a few times a month, then the Deore level is a great component set.
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.
Can I use 9 speed derailleur with 7 speed cassette?
Can I use a 9-speed derailleur on a 7-speed cassette? The answer is
yes
because the rear shift ratio of 9-speed and 7-speed derailleurs is the same if you stay within the same brand.
Can you mix Shimano shifters?
Most 8- and 9-speed Shimano mountain bike and road kit is inter-compatible
because they both use the same cable pull ratio. This means that you can use an 8 -or 9-speed mountain bike derailleur with road shifters or vice versa.
Will 7 speed shifter work with 6 speed cassette?
You would need to either add a 7 speed cassette or use 7 speed spacers on the current 6 speed cassette
. Are you sure it’s a cassette? Many 6 speeds are freewheel. The derailleur should work fine.
Can I use 11 speed derailleur with 9 speed cassette?
Hi is it possible to use an 11 speed derailleur with a 9 speed cassette?
Yep with friction shifters it’ll be fine
.
Can I use wd40 on bike chain?
WD-40 is a great bike chain lube water based lubricant and will not only lubricate the chain well, but will also keep it rust and corrosion free
. It also minimizes the accumulation of dirt which reduces the wear and tear of the chain.
Why does my bike creak when I pedal hard?
The most common cause of creaking is the
crank being loose on the spindle
. Remove the crank bolts, lubricate the threads and under the bolt head, and reinstall. Tighten the bolts to the manufacturer recommended torque. Use a torque wrench if possible.
Why does my bike chain skip when I pedal hard?
Most of the time, a skipping chain is caused by
cable stretch
. In the first half dozen rides on a new bike your shift cables stretch the most. They can also stretch over time as you ride. Hippley explains, “It takes cable tension to open a derailleur, which shifts your chain between gears.
Are derailleur hangers universal?
The Universal Hanger should be in everyone’s saddlebags
. If your existing derailleur hanger busts, strips or is totally wonky, the Universal Hanger replaces the drive-side nut on your quick-release skewer so you can get the majority of your gear range back. Absolutely essential for touring or epic mountain biking.

How do I identify my Shimano rear derailleur?
Does SRAM chain work with Shimano?
Shimano and SRAM 11-speed chains are cross-compatible
. If you have a Shimano 11-speed drivetrain, a SRAM chain will work fine and vice versa, however manufacturer’s recommend pairing your components for optimal performance.
Do all bikes have derailleurs?
Most modern bikes are equipped with a derailleur gearing system
– stay with me, we’ll get to the terminology – where the chain runs between many different cogs.
Do I need a front derailleur?
Are Front Derailleurs Necessary? These days
front derailleurs are essentially not necessary, on mountain bikes at least
. Now even high-end road bikes are starting to lose their front derailleurs. With a larger rear cassette, it’s possible to get the same number of gears without the need for a front derailleur.
