Are Freehubs interchangeable?

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.

Considering this, can you change a freehub?

You can either buy a new freehub body or if you're lucky your local bike shop or bike recycling project may have a stash! Your replacement freehub body needs to have the same interface as your old one (meaning the same spline pattern) so it can fit onto your old hub.

Additionally, are SRAM and Shimano Freehubs the same? SRAM and Shimano cassettes, on either road or mountain bike, are interchangeable with each other as the spacing is the same between the sprockets. However, Campagnolo road cassettes will only work with Campagnolo drivetrains.

Simply so, are freewheels interchangeable?

Most multi-speed freewheels have replaceable, interchangeable sprockets. Newer sprockets must usually simply be replaced, as the teeth are not tall enough to allow of restoration: see our article on sprocket and chain wear.

How do you remove a free hub?

The axle is independent of the freehub.

1. Remove set screw from side of drive side locknut.
2. Hold non-drive side cone with cone wrench. Loosen and remove drive side locknut.
3. Pull freehub to remove. Use care not to loose small parts. Note orientation of pawls as you remove freehub.

Do I need a new hub for 11 speed?

4 Answers. Shimano/SRAM 11 speed cassettes are wider than 8/9/10 speed ones. So yes, you need a new, wider freehub body, unless your old one was not very old and used a spacer to fit a 10-speed cassette. Campagnolo cassettes are the same width for 9, 10, and 11 speeds, so you don't need to do anything in most cases.

What is the difference between a freewheel and a freehub?

Both wheels have hubs, but only the rear wheel has a freewheel. On most modern bikes with multiple gears, the freewheel is built into the rear hub and the whole assembly is called a freehub. The freewheel was built into the rear gear cluster and that whole assembly screwed onto the hub.

Can you put a cassette on a freewheel hub?

Cassette Freehubs The cassette Freehub incorporates the ratchet mechanism into the hub body (although the ratchet mechanism is still replaceable).

How do you tighten a free hub?

Are cassettes better than freewheels?

When you're simply cruising along i.e. not pedalling, or going backwards, it spins freely. A cassette is the more modern option and has quickly overtaken the freewheel. It comprises a collection of independent cogs set on layered rings that come apart and slot onto the body of the (also more modern) freehub component.

Do all cassettes fit all hubs?

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.

Are 8 and 9 speed cassettes the same width?

8, 9, and 10 speed Shimano and Sram cassettes are the same width. You can 'upgrade' without any other modifications. Your shifters will determine what speed cassette and chain you use. If 9 speed it is a direct swap, if 10 speed there is an additional spacer between hub and cassette that should come with the cassette.

Can I replace my 8 speed cassette with a 10 speed?

Simply put - 8, 9, 10 speed cassettes all fit on the same hub. A seven speed cassette will fit on an 8 speed freehub with the use of a spacer. (One notable exception is the Dura Ace FH-7801 hub with an alloy freehub which will only accept 10 speed Shimano cassettes - the newer Dura Ace hubs can run 8/9/10).

Can 9 speed cassette change to 10?

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.

Can I change my 8 speed to a 10 speed?

Yes, it will fit fine. 8,9,10spd freehubs are the same. If it's road you're talking about then you'll need a 1mm spacer behind the cassette if it's Shimano, if it's MTB then it'll go straight on.

Can I put a 7 speed cassette on a 6 speed hub?

7-Speed Freewheels. For frames with 126 mm or wider spacing. These will generally work on hubs made for 6-speed freewheels, sometimes with the addition of a washer or two.

Are all freewheels the same size?

Freewheel threads on modern bikes are the same. Regardless of where in the world the bike is made, the standard (ISO) for freewheel mounting threads is 1.375 inches in diameter and 24 threads per inch. This means that any modern freewheel is likely to fit a standard threaded hub.

Is SRAM and Shimano compatible?

Does SRAM NX use XD driver?

The big change for NX Eagle is the splined-driver-style cassette. The XD driver that SRAM has been using for the last several years works well and is great in terms of making a lightweight system with a wide range of gears.

What is XD compatible?

The XD interface is designed for mountain bike applications and maintains the same hub spacing and flange locations used for 8, 9, and 10-speed compatible HyperGlide freehub bodies. The XDR interface is 1.85mm longer than XD and is designed for road hub applications.

Can you put a 8 speed cassette on a 11 speed hub?

8 speed cassette is basically same width as 9 and 10 speed. If you want to use any of this on an 11 speed freehub, all you need to do is take 1 11 speed spacer and put it behind your last cog before the spokes and then adjust the limit screws. This should cover off the addtional width of the 11 speed hub.

Are Shimano and SRAM 11 speed cassettes compatible?

Sram Shimano MTB Cassette compatibility — 11 speed. If you ask Sram or Shimano, they will tell you that their 11 speed MTB cassettes are not compatible with one another. But running the XT M8000 11–46 cassette gives your Sram 1x11 system a lot of legs too.

Can I put a 10 speed cassette on an 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).
