The cassette body, I believe, is merely the group of 7 sprockets in the back...or some are 8-9 sprockets. So that spacer will take up some space on the hub so the narrower "7 sprockets" cannot slide back-and-forth on the hub. Everything should work just fine I think. You just might have to be careful when shifting in the back so that the chain doesn't derail.

Someone with much more experience will hopefully answer your post soon.

Don't forget, you might need to get these two tools to be able to "swap" your cassette to the new wheel assembly. Please make sure that these tools are the correct ones for your set-up first... I am just posting these links as an example:

Actually the cassette body is the part of the wheel that the cassette (gear cluster) slides on. It is connected to the hub.

Here is a picture of a cassette body.

That's what I meant... (I tried!)

I was confusing cassette body with cog-set (group of sprockets) I think. The rest of my links should still be helpful I believe.

The 8/9 speed cassette body is actually wider than the 7 speed cassette body (makes sense heh). The spacer allows the narower cassette to fit on the wider cassette body.

You will definately need the tools listed above.

LOL, no biggie. It's a little confusing since the cassette body is rarely ever even mentioned, it is generally just considered to be part of the hub. Most of the time people mention cassette they are refering to the cog-set.

LowCel, to help the original poster out...how do you prevent the rear derailleur from shifting the chain onto the "phantom cog"? (i.e. spacer)

I think that would benefit the OP as well. (plus I would like to know )

The derailleur should already be set up for 7 speed. As long as the limit screws are not messed with there shouldn't be any problem. Nothing will really be changed, he will be using the same cassette and derailleur. The only difference will be a small space between the cassette and the spokes.

If you are staying with 7 speed then no you do not need to buy an 8 speed cassette. You can use the 7 speed cassette that you already have. The cassette body is part of the wheelset that you are buying.

You should only have to buy:

Wheelset
spacer
chainwhip
Cassette Lockring remover
grease

However, since you are not very familiar with what you are doing I would recommend going to a shop to have the cassette removed from your old wheel and installed on the new bike. Ask them if you can watch though, this way you will know how to do it next time. A good shop should only charge you $5 - $10 to change the cassette over.

From what I can tell, you only need to buy 3 more items besides your new wheel set.

1) chainwhip tool

2) cassette lockring tool (doesn't have to have the guide pin)

3) spacer

The hubs on your new wheels should already have the cassette BODY installed and ready to go. All you need to do is take your old cassette/cog set/group of sprockets, whatever you want to call it, clean them up and put them onto the new cassette BODY with that spacer. Make sure your old cog set is not worn too much.

(there are different ones you can get for chain whips)

I think you can do it yourself...and the tools are cheap. You'll have more satisfaction doing it yourself. Park ranks it as a novice chore.

The FIRST thing you need to do is stop with the AOL'ese and take some pride in what you post.

You need the following:
  1. Chainwhip
  2. Cassette lockring remover and a wrench to turn it. A big adjustable wrench is FINE
  3. the spacer 1.5mm if I remember correctly
  4. As for the grease opinions vary on this I put alight coat of grease on the freehub body which is the part the cogs mount to. Go to your local Home Depot or whatever you have and pick up a can of Marine Trailer Grease It will come in more handy as you become more experienced
  5. Print out these instructions http://www.parktool.com/repair_help/FAQcogs.shtml

One thing to note...

If you do not have experience as a mechanic (i.e. auto, motorcycles, bicycles, etc) and do not feel like you can handle the task, please take it to a bike shop as lowCel suggested.

Yes I know, It would be cheaper to just bring the two wheels to the lbs to have the cassette swapped.
