Are Shimano 8 and 9 speed compatibility?
Shimano derailleur compatibility 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.
Can you use a 9 speed derailleur on an 8 speed bike?
yes you can use the derailer on the 8 speed cassette. The major difference between 8 and 9 speed is indexing. So for an 9 speed cassette you would need 9 speed shifters.
Can you use a 10 speed derailleur on an 8 speed bike?
You will need a 10 spd rear derailleur to work with a 10 spd cassette, because the spacing is smaller with a 10 spd setup. You will need a 10 speed chain for a 10 speed setup, a 9 speed chain for a 9 speed setup and any 8 speed chain will work on 8-7-6 speed or lower.
Can I use a 9 speed front derailleur on a 8 speed?
In practice, they are interchangeable. You can use a 9 speed FD on an 8 speed crank.
Can I change my 8 speed to a 9 speed?
Convert an 8-speed wheel to a 9-speed wheel. Simply remove the current 8-speed cassette sprocket and replace it with a 9-speed cassette sprocket to convert to 9-speed. If your current wheel is an 11-speed wheel, it should have a 1.85mm low spacer in it, so you can use the spacer as is.
Can you replace a 8 speed with a 9 speed cassette?
Since the 8-speed sprocket and the 9-speed sprocket are the exact same size, it is possible to convert to 9-speed without changing the wheel. Simply remove the current 8-speed cassette sprocket and replace it with a 9-speed cassette sprocket to convert to 9-speed.
Will 11 speed derailleur work with 8 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.
Can I use a 7 speed derailleur on an 8 speed cassette?
8 speed shifter and cassette, 7 speed derailleur? You’ll be fine. There’s no “probably” about it. 6-, 7- and 8-speed gear is all cross-compatible in terms of chain width.
Will an 8 speed cassette fit a 10 speed hub?
Assuming the hub is a freehub design (the freewheel mechanism is in a splined body onto which the cassette (sprockets) fit), no. 8, 9 and 10 speed cassettes are all the same width.
Can I put a 9 speed cassette on a 8 speed hub?
Yes. 8 and 9 speed cassettes are interchangeable.
Are Altus and Acera the same?
Shimano Altus and Acera Due to the blending of the components and technology with the Shimano family, Altus and his big brother Acera are often referred to in the same breath, namely as Acera Altus. Acera Altus only comes in a 3x system – in other words, with a triple or 3-ring chainring at the crankset.
Will a 10-speed cassette fit on an 8 speed hub?
Also be aware that prolonged use of a 10-speed cassette on an 8/9-speed freehub body will cause dents to form in the freehub body (because the 10-speed cogs are so narrow). The 10-speed freehub bodies have taller splines, so they avoid this problem (but don’t work with 8- or 9-speed cassettes).
