Condensed answer: A 9-speed MTB hub can accept an 11-speed MTB cassette. However, a 9-speed Road hub is not compatible with an 11-speed Road cassette.
Can I use a 11 speed cassette with a 9 speed derailleur?
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 replace a 9 speed cassette with a 10 speed?
You can put a new 10 or 11 speed cassette on any of the older 9 speed hubs. So, regardless of brand, feel free to buy your wheels a nicely upgraded new steed.
Can I put an 11 speed cassette on my bike?
Luckily, many common and not-so-common wheelsets, as long as they're at least 10-speed, can be upgraded to 11-speed by purchasing a new cassette body. The body is the part that attaches to the center of the hub and drives the wheel and bike when you pedal.
Can I upgrade my bike cassette?
Of course yes, anyone can change a bike cassette by himself, it's not hard bike mechanics, you need specific tools for the process, but if you're not sure or you don't have the tools at the moment, it's always better to give it to a professional bike mechanic for a quick change.
39 related questions foundAre all 11 speed cassettes compatible?
When SRAM entered the road groupset market in 2006, it decided to adopt Shimano's specifications for its chains and cassettes. As a result, the chains and cassettes from the two brands have always been completely interchangeable for any given type of transmission (e.g. 11-speed).
Are all cassette spacers the same?
The width of spacers is different between brands and models within the same brand. And most high end cassettes do not use spacers or not that many depending on the level. Would be easier to just get the right cassette, since if you are changing the number of speeds you also need a new chain shifter and derailleur.
Do you use spacer with 11 speed cassette?
Re: Shimano 11 speed cassette, spacer ring - is it required
If you have a 'road' 11s length freehub body then you do indeed need to use a spacer to fit CS-HG800-11 to it.
What spacer do I need for a 9 speed cassette?
If you have a 9-speed cassette, you only use the 1.85mm spacer.
Are 9 speed and 10 speed cassettes the same width?
they are the same width. The distance between the 9 speed gears is ever so slightly wider than on a 10 speed cassette (hence why 10 speed chains need thinner side plates than 9 speed ones.
Which is better 9 speed or 10 speed?
Depending on what manufacturer you go for, 10 speed is usally only one more speed than a 9 speed, and not even so because your gear ratio don't change much. Ten speeds are harder to deal with in setting up because they tend to be more finicky.
Can I use a 10 speed derailleur with a 9 speed cassette?
Condensed Answer: 10-speed Shimano and SRAM MTB derailleurs have a different rear shift ratio than 9-speed derailleurs and cannot be effectively combined with a 9-speed shifter and cassette.
Can I use an 11 speed rear derailleur?
Some 11-speed rear derailleurs have the same rear shift ratio as 10-speed derailleurs. SRAM's 10 and 11-speed Exact Actuation Rear Derailleurs have a 1.3 rear shift ratio. Hence why it's possible to use an 11-speed SRAM derailleur from those series with a 10-speed SRAM shifter.
Do SunRace cassettes fit Shimano hubs?
SRAM, SunRace, IRD: mostly compatible
Most cassette hubs are compatible with Shimano cassette cogs. SRAM cassettes and most Miche, IRD and SunRace cassettes use the same inter-sprocket spacing as Shimano, but at least some SRAM 10-speed cassettes do not fit aluminum-body Dura-Ace hubs.
Can I use an 11 speed derailleur on a 10 speed cassette?
No, that will not work. The shifts will not line up across the entire range, because an 11-speed cassette is not just a 10-speed cassette with an extra cog stuck on at the same spacing.
Does an 11 speed cassette need 11 speed hub?
It was my understanding that 11 speed cassettes did not require a spacer when fitted to the latest hubs and that they are only required for 10/9 speed cassettes, so was suprised by this, however this may explain the rattling noises I hear when riding over rougher road surfaces.
Where do the spacers go on a Shimano 11 speed cassette?
These spacers go onto the freehub body before the cassette. Tighten the cassette lockring to 40N-m. If you don't have a torque wrench this can be described as “pretty friggin' tight!!” and you should have your forearm muscles bulging a little.
Are Shimano 11 speed road and MTB cassette compatibility?
Yes it's fine to run Shimano 11 speed mtb cassette on 11 speed road hub. Just remember you need a mounting spacer for the free hub, as mtb 11spd have the same spline length as road/mtb 9-10 speed etc.
Can I put an 11 speed cassette on a 9-speed hub road bike?
An 11-speed cassette will fit on a 9-speed hub only when the hub is wide enough. Luckily, 8,9,10 and 11-speed mountain bike hubs have the same spacing, and one can therefore use an 11-speed cassette on all of them.
Can I put an 8 speed cassette on a 11 speed hub?
Condensed answer: An 8-speed cassette can be installed on an 11-speed hub. If the hub is designed for an MTB, the cassette should fit right away. If the hub is made for a road bike, a 1.85mm spacer will be needed for a secure fit.
Can you put a 7 speed cassette on a 9-speed hub?
7-speed cassettes fit fine on 8- and 9-speed (and most 10-speed) hubs if you put a 4.5 mm spacer onto the body before the cassette.
Are Campagnolo and Shimano 11 speed compatibility?
Yes they are. The 11 speed cassettes of Shimano and Campagnolo have the same sprocket spacings and overall widths, so you can swap a Shimano wheel/freehub/11sp cassette with a Campagnolo wheel/freehub/11 speed cassette. Rest of the bike can be Shimano or Campag 11 speed, it doesn't matter.
Are all Mavic wheels 11 speed compatible?
Mavic wheels are completely compatible w/ 11 speed Shimano or SRAM cassettes... pull off the thick Mavic spacer and you're ready to go.
Can I use a Shimano cassette with Campagnolo?
Yes. Campagnolo wheels are compatible with both Shimano and SRAM components. In order to use Campagnolo wheels with any drivetrain on the market, Campagnolo produces two kinds of freewheel bodies: one specific for Campagnolo drivetrains (from 9 to 11 speeds) and one for non-Campagnolo drivetrains (from 9 to 11 speeds).
