Can I use 7 speed cassette on 8 speed hub?

Can I change 7 speed cassette with an 8 speed?
Yes, 7 and 8 speed chains are the same but you’ll want a new chain to run on the new cassette.
How do I change my 7 speed bike to 8 speed?
An 8-speed sprocket is 3.6 mm taller than a 7-speed sprocket, so if you try to install an 8-speed sprocket on a 7-speed wheel, the lock ring that holds the sprocket in place will not tighten. Therefore, it is necessary to replace the wheel with an 8-speed wheel or higher.
Are 7 and 8 speed hubs the same?

Are bicycle cassettes interchangeable?

Will any cassette fit any hub?
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 upgrade my 7-speed to 10 speed?
Yes, in most cases this upgrade is possible, without the need for replacing the rear-wheel hub body, you only need to change the chain, shifter and readjust your rear-derailleur, when upgrading to a super big ratio cassette, you may need to change the rear-derailleur completely to a new one with a wider cage in order …
Are more gears better on a bike?
Gear Ranges on Bikes Broadly speaking, mountain bikes have lots of low gears so you can climb steep hills more easily, while road bikes have more higher gears to boost top-end speed. More gears means more choices, but also more complexity for riders (and shop techs).
Can you change cassette size?
Yes, you can. If a smaller cassette suits your needs and terrain more, there’s no reason why you can’t put it on your bike. It doesn’t affect the function of your bike or drivetrain in any way and shifting will not be different.

Can a 7-speed chain be upgraded to 8-speed?

What is the difference between 7-speed and 8-speed transmissions?
7 and 8-speed systems use a relatively wide, and almost identical, spacing between sprockets, and the same tried-and-true chain. 8 or more speeds require a longer rear axle. Rear-wheels get weaker as dishing becomes more extreme.
