Will a 9 speed freewheel fit a 7 speed hub?

7-speed hubs won’t normally accept 8-, 9- or 10 speed cassettes without modification. Click here for details. 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. Click here for details.

Can you fit a 7-speed cassette on an 8 speed hub?

A new 7-speed cassette will work correctly with a 4.5mm spacer; but there were so many variants of older cassettes that it is difficult to be certain what will work. Your best solution is probably to purchase a new cassette, as compatibility with an 8-speed cassette body using the 4.5mm spacer will then be correct.

What is the difference between freewheel and freehub?

Freehub vs freewheel



Freewheels predate freehubs. They’re still found on older bikes and the majority of modern single-speed bikes. They’ve been superseded by the freehub on multi-speed bikes though, as it’s lighter and more compact, so it can handle smaller sprockets and wider gear ranges.

Will an 8 speed chain work on a 9 speed cassette?

No it won’t work tolerably.

Can you fit an 11 speed cassette on a 9 speed hub?

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 fit a 10 speed cassette on a 9 speed hub?

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.

Will I need longer chain for a bigger cassette?

You need a bit longer chain for a larger cassette. All things remaining the same, if your chain was the correct length before, adding the 34t gear increases the diameter of the low gear. That increases the total gear length, so you would have to have more chain to keep the adjustment correct.

What’s the difference between a freewheel and a cassette?

The freewheel is a single-unit and the act of pedaling tightens the freewheel to the hub. Whereas the cassette hub is a set of gears (cogs) that slides onto a cassette and is held in place by a lock ring.

Why is a cassette better than freewheel?

A cassette is the modern alternative and has quickly overtaken the freewheel. Cassettes have a series of straight splines that form the mechanical connection between the sprockets and the cassette-compatible hub, which is called a freehub and contains the ratcheting mechanism.

How do I know what size freewheel I need?

Quote from video: On a bike it can be difficult to determine if you have a cassette or free will but this is the simplest way. After you remove the rear wheel from the bike spin the sprockets backwards.
