How do I fit an 11-speed cassette on an 8-speed freehub?
...with a lot of preparation and one blow with the sledgehammer?
Well, seriously, I've got a Merida Race Lite 900 bike in Spain (I live in Finland) that I like. The frame, fork and other non mechanical things are quite good. The shifters, breaks, cassette and the rest...not so great. I now ordered a Shimano 105 (5800) groupset for it. Everything should be compatible except for the 11-speed cassette. The Merida has a Shimano FH-2200 freehub which, as far as I can tell, does take up to a 10-speed cassette. Getting the 11-speed cassette on the freehub does pose a problem...
As I see it there are a few possible solutions:
1) Get a freehub body from an FH-5800 freehub and install it on the FH-2200. Does the body fit? The body fixing bolt is the same for both hubs...
2) Get a 10-speed cassette, this should fit on the FH-2200 freehub but then I must limit the rear derailleur so that it doesn't travel too far. Can it be done? Will it work?
3) Remove 1 ring from the 11-speed, although it doesn't seem to be possible with 11-speed? And a 10-speed cassette is only 30€.
4) Rebuild my wheel with an FH-5800 hub. This sounds fun but I run the risk of creating a corkscrew, never redone a wheel before. Even worse would be to get a working wheel that would "explode" in the first high speed roll down a hill.
5) Get a new wheel with a compatible hub.
Obviously #5 would be best but also most expensive and problematic: I can't be sure to quickly find a compatible wheel for a reasonable price in Spain and lugging one with me on the plane would cost extra.
#1 would be great if it is workable and #2 will do until I can fix a wheel in case #1 doesn't work.
So what do you think would be my best bet, or am I screwed?

1-No, does not fit
2-You can allways limit the travel, but the spacing of a 10 speed cassette is different and shifting is erratic.
3-Cannot with most cassettes,but you can try to drop the useless 11.....
4-Best option
5-Your choice0 -
I vote for #4. Read up/watch videos to learn how to do it and have your LBS check your work (for a fee of course but worth it). I'm pretty sure both hubs use the same length spokes in which case you can just use the old spokes with the new hub.0

you can buy a similar wheel to what you ve got but 11sp, for less than £50 or a complete set of rs21 s for about 115

Thanks for the advice guys.
I eneded up taking the safe and expensive before the adventurous and ordered a new wheel set. I found the WH-RS11 on bike-discount.de for 110€ and had it shipped to a neighbour in Spain who is there to sign for it.0
