Different Derailleurs with different shifters

Asked by: Judy White
Do shifters and derailleurs have to match?
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.
Can you use any shifters with any derailleurs?
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.
Can you mix shifters and derailleurs?
In many instances, it is possible to mix different levels of shifters and derailleurs from the same brand (e.g. Dura-Ace/Ultegra/105; Red/Force/Rival; Super Record/Record/Chorus), however it’s not safe to assume that this will always be the case.
What are the different types of shifters?

Can you use a SRAM derailleur with Shimano shifters?
The SRAM rear derailleur (mech) will not work with a Shimano shifter as is; the cable pull and shift activation ratios are not the same between the two systems.
Can I use an 11 speed derailleur on a 10 speed shifter?
Can An 11-speed Derailleur Work With a 10-speed Cassette and Shifter? Condensed Answer: Shimano’s 11-speed derailleurs have a different rear shift ratio than 10-speed derailleurs and are therefore not compatible with 10-speed indexed shifters.
Do all derailleurs fit all bikes?
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.
Can you use a 7 speed shifter on a 6 speed bike?
Re: Can you use a 7 speed shifter on a 6 speed cassette? The “numbers” say they don’t match. The cable pull of a 7 speed is less than a 6 speed so, though a couple of cogs might work, the rest will gradually not. You’ll never know if you don’t try it.
Can I use a 9 speed shifter with a 7 speed cassette?
If you used a 7 speed cassette, with a 9 speed shifter and 7 speed derailleur you would not pull enough cable and the shifts will get mangled. If you are currently on 7 Speeds, this means you have a 7 speed wheel that will most likely NOT take a 9 speed cassette.
Are all Shimano shifters compatible?
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.
Can I use 105 shifters with Ultegra derailleur?
The parts of DURA-ACE, ULTEGRA and 105 are compatible with each other as long as they have the same number of gears.
Are Shimano 11 and 12 speed compatibility?
The 12-speed cassette is designed to be backwards compatible with the existing 11-speed road freehub, while the 12 speed-specific freehub (available on Dura Ace hubs currently) can’t be used with the 11-speed parts. Sram HG-style cassettes are largely the same spacing as Shimano, with the 10 speed exception.
Can you use a Shimano rear derailleur with SRAM shifters?
Sram rear derailleurs require a 1:1 cable actuation ratio, Shimano rears require a 2:1. So you can not mix and match Shimano and SRAM rear derailleurs and shifters.
Are SRAM and Shimano cranksets interchangeable?
SRAM cranks are compatible with Shimano chainrings when both components are designed for the same mounting system (BCD).
Will SRAM X4 work with Shimano shifter?

Can you mix and match Shimano components?
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.
Will a 9 speed shifter work on a 7 speed cassette?
If you used a 7 speed cassette, with a 9 speed shifter and 7 speed derailleur you would not pull enough cable and the shifts will get mangled. If you are currently on 7 Speeds, this means you have a 7 speed wheel that will most likely NOT take a 9 speed cassette.
Can you use a 7 speed shifter on a 6 speed bike?
Re: Can you use a 7 speed shifter on a 6 speed cassette? The “numbers” say they don’t match. The cable pull of a 7 speed is less than a 6 speed so, though a couple of cogs might work, the rest will gradually not. You’ll never know if you don’t try it.
Are all Shimano 9 speed shifters compatible?
Combining with various RDs:
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).
Will a 9 speed derailleur work on a 10 speed cassette?
Theoretically a 9 speed derailleur will work with a 10 speed shifter and cassette. On the MTB side the change to a different actuation ratio was made at 10 speed, so a 9 speed MTB derailleur will not work with a 10 speed shifter and cassette.
Will an 8 speed derailleur work on a 9 speed cassette?
Yes, your XTR derailleur will work with 9 speed shifter and cassette. 8 and 9 speed Shimano RD’s are for all practical purposes interchangeable.
