Can I use an 8 speed cassette, slap it on this wheel, and then slap this wheel on a bike that has 7 speed shifters and derailleurs?

Yes, you just won't be able to shift to either the biggest or smallest cog, depending on how you set your limits. But why not just use a 7 speed cassette?

i dont think it would. a 6 gear assembly may be narrower than a 7 gear one, this wheel may be too wide for a six speed bike rear fork.

No this is designed for shimano or sram cassettes only. This will work with 8 through 10 speed cassettes I think a 7 speed will work but needs a spacer.

It will accept any standard cassette, a six speed cassette will be a bit narrower than an standard 8 speed but there should be shims to take up the space. The rims are nice and a lot lighter than the ones that came on my bike. I also fitted them with big apple tires, which are belted and puncture resistant and the ride is nothing short of amazing. I think the wheels are a good value.

Yes. A 7-speed & 8-speed have the exact same amount of spacing between sprockets. The only thing is that one of the gears on your shifter won't be used for anything. If it were the other way around, then you would not be able to shift to one of your eight gears with a 7 speed shifter.

I would not be inclined to try it, the 10 speed chains run best on 10 speed gears, on the "less" gears while I know you can put a 10 speed chain on a 9 speed cassette it is more difficult to maintain / tune as the 10 is a narrower chain so from my experience I would not try it, the KMC is a beautiful chain for the 10 speeds. KMC does make 7/8 speed chains for the thicker gears, but I am not sure they have it in colors the KMC model I think for 7/8 is the Z51 that is set for 6/7/8 speed specifically, I would be inclined to go that way for the KMC chain

7-8 speed refers to the rear gears on the cassette. That's what really matters here. If the back has 7 or 8 gears, it will work. They come up with 18/21/24 by multiplying the number of front gears (usually 3) by the number of back gears. 3 x 7 = 21 or 3 x 8 = 24. Frankly, I don't know how they come up with 18, because that would be a 6 speed rear.

Yes. I am currently using a 7 speed cassette on this hub. However you will need a spacer as the width of the 7 speed cassette is not the same as the 8 speed cassette.

The left shifter is two speed friction, I haven't run a triple with it but you may be able to rig it; the right shifter is 7 speed indexed.

Depends on the existing deraileur, things like long cage and shifter components being shimano compatible have to be there. Chain length may need to be addressed.

yes, assuming you have 7 speed rear deraillure shifter and chain. The width of the cassette is usually the same, it's the width of the gears plus spacing between the gears that are different.

Yes as long as your gear count is the same. For example, if you have a 9-speed shifter and cassette you need a 9-speed derailleur. Same with 10-speed. If these match you are fine mixinh 771 and 772 component sets.

You have to change the hub out to accept a cassette. Freewheels only thread on up to 7 speed. I'm pretty sure about that but your local bike shop will know for sure

No. Chain will be too wide for the spacing in between the cogs on the cassette. You will need a 9 speed specific chain

This wheel will work,but you will need a 4.5mm spacer for your 7 speed cassette.http://www.amazon.com/Wheels-Manufacturing-Cassette-Spacer-Converts/dp/B001CJVLWO/ref=sr_1_1?ie=UTF8&qid;=1409095921&sr;=8-1&keywords;=4.5+mm+spacer

Usually cassette sizes 7,8 & 9 are compatible. It's a newer bike so I think you should be fine. Remember if you decide to switch the speeds on the bike you're also going to have to switch the shifters if they are not compatible to the speed...

Yes, but most newer hubs are made for 8 to 9 speed cassettes. In which case you will also need a 7 speed spacer ring (about $2.00). Spacer ring goes on hub first, then the cassette.
