Are All Shimano Freehubs The Same?

Are all Shimano Freehubs the same? Most Shimano Freehub bodies are interchangeable. The exceptions are: FH-7850 and FH-7900 Dura-Ace bodies, which have returned to a splined attachment between Freehub body and hub shell, but it is larger than the usual one. It is similar but not interchangeable between these two models.

Are Shimano 10 and 11 speed hubs compatible?

A 10-speed Shimano or SRAM cassette can still be fitted to an 11-speed body, but a spacer will be required to make up for the difference in width. There is another, more subtle, incompatibility that affects different brands of hubs and wheels, but it will only have an impact on those riders using multiple wheelsets.

Can I put an 11 speed freehub on a 10 speed wheel?

Are 10 and 11 speed hubs the same?

The Shimano (and SRAM) 11-speed freehub is wider than the 10-speed one, because the 11-speed Shimano (and SRAM) cogset stack height is taller than 10-speed.

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.

Will 11 speed shifters work with 10 speed derailleur?

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.


Can you use a 11 speed rear derailleur on a 10 speed cassette?

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.


How do you install a 10 speed cassette on a 11 speed hub?


How can I upgrade my 10 speed to 11 speed?


Can I upgrade my freehub?

Yes. You can replace just the hub, but you'll likely need new spokes, and a decent mechanic will charge $50+ for the job. Unless you have a really nice rim, that's not worth it. Buying a new wheel makes more sense.


What is the length of 11 speed freehub?

Without spacers, the freehub is just shy of 37mm (no accurate calipers on hand). This website popped up when I searched for 11 speed freehub width which seems to suggest my freehub is the right width, but it seems to be the only site that lists the width that I can find, so was hoping for a second opinion.


How wide is a 11 speed freehub?

This puts the hub at 131mm wide, which will fit into a standard 130mm spaced road frame with no problem and likely cause no alignment issues.


Will 11 Speed fit my hub?


Can I upgrade my 11 speed to 12?

The Ratio 12-Speed Upgrade Kit allows you to operate an Eagleā„¢ derailleur with your existing SRAM 11-speed shifters, gaining an unbeatable 500% or 520% range and 12 evenly spaced gears on your gravel, road or touring bike.


Are 11 and 12 speed chainrings the same?

fmendes said: The chainring on a 1x system will only "see" the internal of the chain, so yes, a 11 speed chain will work fine with a 12 speed chainring (that's usually 11/12sp chainring). But Shimano created a new tooth profile for their 12-speed chainrings that matches the internal parts of their new 12-speed chains.


Can I replace my 9 speed cassette with a 11 speed cassette?

You'll need to change the chainwheels and the cranks, the rear derailleur, the brake-shift levers, the cassette and the chain of course. The rear wheel probably has an older hub but then if you're lucky and the hub is designed for 10-speed as well it will also take 11.


Can I convert my 9 speed to 11 speed?

Converting a 9-speed wheel to 11-speed

You will have to buy a new 11-speed wheel and replace the entire wheel. On the other hand, if your current wheel is an 11-speed wheel, you can convert it to 11-speed by removing the low spacer from the low side of the 9-speed sprocket and installing an 11-speed sprocket.


Can you fit an 11 speed cassette?

To upgrade a bicycle to an 11-speed components group requires your existing rear wheel to accept the 11-speed cassette. It can look like it's permanently built into the hub, but on most wheels it's replaceable should it wear out or should you want to upgrade to more gears.


Can I put an 8 speed cassette on an 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 I put a 10 speed cassette on a 9 speed hub?

The most you should need to do to allow a 10 speed cassette to work on most 9 speed hubs is install a spacer behind the cassette to make sure the cassette seats tightly. You can put a new 10 or 11 speed cassette on any of the older 9 speed hubs.


Do I need spacer for 10 speed cassette on 11 speed hub?

Use spacers on the 11 speed wheel to put a 10 speed cassette on. See your hub manufacturer's page for details, but its normally a 1.8(5) mm spacer (which comes with the hub, but you can buy separately) and a 1mm spacer (sometimes; which you'll get with the cassette).
