Can I use a 10 speed shifter on a 9 speed derailleur?
Can I use a 10 speed shifter on a 9 speed derailleur?
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.
Can you mix Shimano shifters and derailleurs?
For those riders with 10-speed Shimano groupsets (except Tiagra 4700), the shifters can be paired with the company’s 9-speed MTB rear derailleurs to accommodate larger rear sprockets (in some cases, up to 40T) while enjoying perfectly indexed shifting.
Are all Shimano 9 speed shifters interchangeable?
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).
Can I use 11 speed shifter with 9 speed cassette?
No, an 11 speed road shifter has a different pull ratio than an 8, 9 or 10 speed. Any 8, 9 or 10 speed road shifter will work with any 8, 9 or 10 speed road rear derailleur (unless it’s Tiagra 4700). However, the 11 speed road system pulls more cable per shift and therefore is not backwards compatible.
Does rear derailleur speed matter?
The shifter determines how far the derailler moves. It doesn’t matter is the derailler is 8 or 9 or 10, it will shift however far the derailler lets it. “Don’t those guys know they’re old?!!”
Can I use 11-speed derailleur with 10 speed shifter?
the 10 speed and 11 speed derailleurs are interchangeable as far as the shifters go, the difference is that a 10 speed derailleur doesn’t like a cassette cog much bigger than the 36t it was designed for, where the 11 speed derailleurs are designed for 40 and 42t cogs, and seem to be able to handle bigger.
Can you use a 10 speed shifter on a Shimano?
Accordingly, to use this shifter as a 10 speed shifter (with one un-used click) with a 10 speed derailleur and cassette, we need to reduce movement at the derailleur arm by about 5.5%. It works!
Can you use a Shimano road 10 speed derailleur?
Almost there, it won’t work. Njee20 is right (except all Shimano road 10 speed is the same rear cable pull, it’s the front that is different on 7900, 6700 and 5700). Just to reconfirm, you can’t mix Shimano 9 and 10 speed rear mechs and shifters.
How much cable does a 10 speed Shimano use?
Basically, the 11 speed Shimano MTB shifters pull 3.6mm of cable per click. 10 speed shifters pull 3.4mm of cable per click. Accordingly, to use this shifter as a 10 speed shifter (with one un-used click) with a 10 speed derailleur and cassette, we need to reduce movement at the derailleur arm by about 5.5%. In practice. It works!
What’s the difference between a 9 speed and a 10 speed derailleur?
What Sssimon says is correct, the new rear mechs have a different leverage so for the same amount of cable pull a 10 speed mech will move less than an old 9 speed one. Just like a Sram rear mech and a shimano shifter- you click the shifter and it’ll move a different distance to a shimano mech with the same shifter.
